Cruise Control

Cruise Control Parameters

1). Low Cruise Control Speed Set Limit
The “Low Cruise Control Speed Set Limit” sets the lowest vehicle speed that will allow the cruise control to be set. Programming this parameter to the maximum value disables cruise control.

* Minimum: 24 km/h (15 mph)
* Maximum: 204 km/h (127 mph)
* Default: 204 km/h (127 mph)

2). High Cruise Control Speed Set Limit
The “High Cruise Control Speed Set Limit” sets the highest vehicle speed that will allow the cruise control to be set. If a driver attempts to set a vehicle speed higher than this limit, the “High Cruise Control Speed Set Limit” will be the cruise set speed. If the “High Cruise Control Speed Set Limit” is programmed to a value that is greater than the vehicle speed limit, the cruise control switches can be used to exceed the programmed vehicle speed limit.

* Minimum: 48 km/h (30 mph)
* Maximum: 204 km/h (127 mph)
* Default: 204 km/h (127 mph)

3). Engine Retarder Mode
The “Engine Retarder Mode” determines the operation of the auxiliary retarder output and the exhaust retarder output while the cruise control On/Off switch is in the ON position but the engine is not in cruise control. This does not determine engine retarder operation while the engine is in cruise control. Also, this does not allow engine retarder operation while the engine is in cruise control.

The following modes are allowable options:

* Coast
* Latch
* Manual

When the “Engine Retarder Mode” is programmed to the coast mode, the engine retarder is enabled only while the service brakes are being applied. When the Engine Control Module (ECM) is programmed to the latch mode, the engine retarder stays enabled after the service brakes are released. A direct, immediate pressure on the brake pedal latches the engine retarder in the ON position and the engine retarder will remain in the ON position until the accelerator pedal is depressed.
When the ECM is programmed to the manual mode, the cruise control switch is not required to be in the ON position. When the ECM is programmed to the manual mode, the engine retarder will activate when all of the following conditions are met:
-The engine retarder switch is in the ON position.
-The engine rpm is greater than 800 rpm.
-The engine is not being fueled.

* Alternative: Coast, Latch
* Default: Manual


4). Engine Retarder Minimum VSL Type
The “Engine Retarder Minimum VSL Type” defines the use of the “Engine Retarder Minimum Vehicle Speed” parameter. The “Engine Retarder Minimum VSL Type” provides the following two options:

* Hard Limit
* Soft Limit

If the “Engine Retarder Minimum VSL Type” is programmed to the Hard Limit, the engine retarder will turn off when the value that is programmed into the engine retarder minimum vehicle speed is reached.

If the “Engine Retarder Minimum VSL Type” is programmed to the Soft Limit, the engine retarder will remain on and the retarder will have a value that is below the value that is programmed in the engine retarder minimum vehicle speed. The engine retarder will remain on until the parameters that would normally turn off the engine retarder are met.

In both cases, the engine retarder will remain off until vehicle speed is higher than the programmed value of the engine retarder minimum vehicle speed and the engine retarder has been engaged again.

The following diagram (Figure 1.5) illustrates the engine retarder operation for both options of the “Engine Retarder Minimum VSL Type”. The engine retarder parameter is programmed to the manual option and the parameter for the engine retarder minimum vehicle speed is programmed to 48 km/h (30 mph).

Note: When the vehicle speed drops below the engine retarder minimum vehicle speed and the parameter is programmed to the hard limit, the engine retarder turns off. When the vehicle speed drops below the engine retarder minimum vehicle speed and the parameter is programmed to the soft limit, the engine retarder remains on.

If the engine retarder minimum vehicle speed has been programmed to 0 km/h (0 mph), the programming of the parameter for the “Engine Retarder Minimum VSL Type” does not affect the operation of the engine retarder.

5). Engine Retarder Minimum Vehicle Speed
The “Engine Retarder Minimum Vehicle Speed” determines the minimum vehicle speed limit for the engine retarders to turn ON. Below this vehicle speed, the ECM will not turn on the engine retarder unless the vehicle is stationary. If the vehicle is stationary, the vehicle speed is 0 km/h (0 mph). If the vehicle speed signal was not being read by the ECM, the vehicle could be moving but the vehicle speed signal would be 0 km/h (0 mph). If engine retarder minimum vehicle speed is programmed to 0 km/h (0 mph) the engine retarder will operate at all vehicle speeds. This parameter affects both the engine retarder and any auxiliary retarder such as a BrakeSaver.

* Minimum: 0 km/h (0 mph)
* Maximum: 204 km/h (127 mph)
* Default: 0 km/h (0 mph)

6). Auto Retarder in Cruise
The “Auto Retarder in Cruise” determines the vehicle speed in kilometers per hour (km/h) or miles per hour (mph) above the cruise set speed when the engine retarder will be activated. The engine retarder switch must be in the ON position and the cruise control must be set for this feature to operate. Programming the “Auto Retarder in Cruise” parameter to zero disables this feature. This parameter affects the engine while the cruise control is activated.

Note: This parameter only affects the factory installed engine retarder (compression brake). This parameter does not affect an auxiliary braking device or Brakesaver.

The actual level of braking is limited by the settings of the retarder switch. For example, the retarder will not come on if the retarder is switched off.

If soft cruise control is programmed to yes, the retarder will not come on until the vehicle speed is 5 km/h (3 mph) above the cruise set speed. The Caterpillar Electronic Technician (ET) will change an attempt to program 2 km/h (1 mph) or 3 km/h (2 mph) for this parameter to 5 km/h (3 mph) if “Soft Cruise Control” is programmed to “Yes”.

* Minimum: 0 km/h (0 mph)
* Maximum: 16 km/h (10 mph)
* Default: 0 km/h (0 mph)

7). Auto Retarder in Cruise Increment
The “Auto Retarder in Cruise Increment” requires the “Auto Retarder in Cruise” parameter to be programmed above zero. “Auto Retarder in Cruise Increment” determines the increment in kilometers per hour (km/h) or miles per hour (mph) when the medium level of engine retarder will activate. “Auto Retarder in Cruise Increment” also determines the increment in kilometers per hour (km/h) or miles per hour (mph) when the High level of engine retarder will activate. Programming the parameter to zero will allow the retarder to come on in the high mode when the programmed “Auto Retarder in Cruise” speed is reached. The “Auto Retarder in Cruise” speed must be set above the cruise set speed. This parameter affects the engine while the cruise control is activated. The actual level of braking is limited by the settings of the retarder switch. For example, the retarder will not come on if the retarder is switched off.

* Minimum: 0 km/h (0 mph)
* Maximum: 8 km/h (5 mph)
* Default: 3 km/h (2 mph)

. Cruise/Idle/PTO Switch Configuration

“Cruise/Idle/PTO Switch Configuration” defines the function of the Set/Resume switch for “Accel” mode and “Decel” mode. This parameter affects cruise control mode, idle mode and PTO mode.

* Alternative: “Set/Decel-Res/Accel”
* Default: “Set/Accel-Res/Decel”

9). Soft Cruise Control
“Soft Cruise Control” provides a 8 km/h (5 mph) operating range around the cruise control set speed in order to provide a smoother cruise control. “Soft Cruise Control” controls the cruise speed within the following range:

* 4 km/h (2.5 mph) below the set vehicle speed at full load
* 4 km/h (2.5 mph) above the set vehicle speed at no load

* Alternative: No
* Default: Yes

10). Adaptive Cruise Control Enable
“Adaptive Cruise Control” reduces the need to manually cancel cruise control when you approach a slower vehicle. The system responds by decreasing the cruise control set speed until a following distance is obtained. If the slower vehicle speeds up, the cruise control set speed will be adjusted in order to maintain the following distance. “Adaptive Cruise Control” will restore the original set speed when there are no vehicles within the range of control. Adaptive cruise control will not increase the cruise control set speed above the original setting. If the vehicle is approaching the target too rapidly, the ECM will turn off the cruise control.

* Alternative: Enabled
* Default: Disabled

Why & When Need To Bleeding ABS System?

An anti-skid braking system or anti-lock braking system(also short called ABS),it is a hydraulic brake system,the actions of brake system is performed power by hydraulic pressure.The compressive property of brake fluid is excellent,its volume will not be reduced when inflicted strong pressure.Compare to the brake fluid,the air in the brake system have poor compressive property,The volume of air will reduce when it suffering strong pressure.If brake fluid in the brake system is mixed with air,the brake pressure provided by booster pump will work to reduce volum of air when braking,instead of providing the brake pressure directly.So it will make brake system insensitive and expose us under the risk.



There will be a need to replace an ABS modulator or other hydraulic component, such as a pump/motor or even a master cylinder, on some systems.And if your car perform above operations,it most likely that the brake fluid in the brake system is mixed with the air,then you need to bleeding ABS system to enhance brake system performance.

Bleeding ABS Brake System Principle:

The oil circuit of brake system is a closed loop,the method of bleeding air is circulation of loop.Generally,the filling valve of brake system is setted to current path and delivery valve is open circuit,so we just consider the delivery valve.Only active delivery valve to make oil circuit circle circulated.At the same time,press the brake pedal to enhance oil pressure to promote the brake fluid circulate in the loop.


Bleeding ABS System by Special device or Manually?

Usually,a lot of people bleeding ABS by manually,but if you wanna a better effect of bleeding ABS,it is recommand to bleeding ABS by special device.Only air of filling cicuit and brake sub pump can be discharge by manual bleeding,it can not bleeding the air in the delivery valve. All air in the system can be discharged by special device.


How To Bleeding ABS Brake System?

According to the ABS type,the method of bleeding ABS are different:

For BOSCH ABS System:

Order:

Left rear wheel–>Left front wheel–>Right front wheel–>Right rear wheel

1. Before bleeding ABS,you need to open bleeding bolt of left rear wheel.

2. Press brake pedal during bleeding ABS.

3. You will sound the sound of delivery valve actived.

4. When the bleeding complete,the device will remind you to close left rear bleeding bolt and open the left front wheel bleeding bolt.

5. It will remind you to close left front wheel bleed bolt and open bleeding bolt of right front.

6. When the bleeding of right front wheel,the device will active the pump and right front wheel delivery valve.So you will sound the sound of pump.The bleeding of right front wheel and right rear wheel will take more time than left side wheel.

7 When 4 wheel ABS bleeding complete,the device will remind you bleeding ABS completely.



For other ABS System:

Order:

Right rear wheel–>left rear wheel–>left front wheel–>right front wheel

1. Before bleeding ABS,you need to open bleeding bolt of left rear wheel.

2. Press brake pedal during bleeding ABS.

3. When starting bleeding,the device will active pump and delivery valve,you would sound the sound from pump and delivery valve.

4. The pump will work on all the time during bleeding,and delivery valve will open and close alternately.

5. There will be a pause of pump when one of wheel bleeding completely,then the device show closed right rear wheel bolt and open left rear wheel blot,select start to begin bleeding of left rear wheel.

6. Follow the gudie of device to complete bleeding of each wheel.

How to Use Scania SDP3 Reset Service Indicator for Scania Truck

Procedures:

1.Remove the EGR valve from the engine.

2.Check the part of the pipe that connects to the EGR valve. Clean the sealing surface if necessary.

3.Fit the EGR valve in a vice.

Cleaning and inspection for reusing the EGR valve

1.Remove the gaskets and clean the sealing surfaces to the connecting pipe.

2.Mark the position of the EGR valve electric motor (1) in order to be able to refit the electric motor in the same way.

Then remove the electric motor with shim (2).

3.Remove the split collets, valve spring collar and valve spring by doing the following:

Press down the valve spring collar (2) by hand or using a socket. The split collets should then (1) release from the valve stem (4).

Tap carefully with a hammer if the split collets do not come loose.

Once the split collets have released: remove the split collets (1), valve spring collar (2) and valve spring (3).

4.Dry cleaning:

* A thin layer of carbon deposits on the inside of the EGR valve is normal and does not need to be removed.
* Remove the accumulated soot in the EGR valve inlet (1) and outlet (2) with a small nylon or wire brush. Some of the deposits may need to be scraped off.
* Stop scraping when the black soot has gone, so you do not damage the corrosion protection.
* Press in the valve stem for general access, but take care not to damage the valve seal.


* Clean around the soot guard with a 90° scraper.

Wet cleaning:

* Only use carburettor cleaner, this is the most effective detergent to use for cleaning.
* Ensure that the EGR valve is lying horizontally in the vice, with the outlet (2) upwards.
* Plug the inlet (1) and fill the EGR valve with carburettor cleaner through the outlet (2). Ensure that the detergent covers the valve stem.
* Move the valve stem forwards and backwards and twist it when the valve disc is up against the valve seat (closed position). Allow to work for five minutes and then drain the carburettor cleaner.

* There are 2 valve discs located on the valve stem. The illustration shows one valve disc (1).
* Use a small nylon or brass brush to clean around the valve seal (2), valve stem (3) and valve seats (4).
* Take care not to damage the sealing surfaces. Use additional detergent if necessary.
* The soot guard consists of an inner and outer cylinder which must be closed with a gap at the bottom.
* Use a small nylon or brass brush to clean around the soot guard. Use additional detergent if necessary.
* Empty the remaining detergent and use compressed air to blow the EGR valve clean.
* Repeat the wet cleaning if necessary.

A clean EGR valve gives a metallic sound when it closes. If any deposits remain that keep the valve open, the valve closes with a duller sound.

5.Reset the EGR valve:

* Fit the valve spring (3) and valve spring collar (2).
* Place the split collets (1) on the valve spring collar.
* Hold the valve stem (4) from the opposite side with one hand. Press down the valve spring collar with the other hand, or using a socket until the split collets are below their locking position on the valve stem.
* Position the split collets carefully against the valve stem and release the pressure on the valve spring collar.


* Refit the EGR valve electric motor (1) and shim (2) to the EGR valve.

Standard finishing operations

1.Check the harness-to-harness connector (1) to the EGR valve electric motor. There must not be any rust or wear.

2.Fit the harness-to-harness connector to the EGR valve, connect the battery and switch on 15 voltage without starting the engine.

It is normal for soot and condensate to run out of the overflow opening (2).

3.Connect the diagnostic tool and check whether fault code 1896 remains. If fault code 1896 remains, the EGR valve must be renewed.

4.Fit the EGR valve on the engine.
