My Car Refuses To Be Scanned! by CHIMSKY(m): 1:26am On Aug 16, 2013 |
I drive a Camry 98.My problem is that I can not scan my car anymore.Anytime I connect my scanner or my mechanic connects his to the charging port,the car does not recognize it and so no connection is established.I have gone to several auto electricians but they dont know what the problem is.Initially I thought it was the fuse but its not. What could be the problem? |

they don't know what they are doing. Unless someone has messed with your computer your car will so a code if any exist. |

It could be the scanner lack the ECU protocol of your car. Even my scanners lack the protocol of that particular ECU and so dont communicate with the ECU of that particular Camry model year, especially the petrol N/A I4. Try other scanners, unless someone has messed with the wires to that port. Ikenna |

Chimsky, it is usually a fuse but where you find no issues with the fuse then there is a bad wire in the ECM harness 1 Like |

Not quite. The OPs scenario happens more often than you think. Infact I have attended to at least 2 Nairalanders with the same issue. In my experience, it is caused by either of the issues I referred to earlier or the ECM is damaged. The OP already implied he hasnt used only one scanner to test this and possibly the same scanner has been used successfully previously 1 Like |

Maybe the wire connecting it 2 d brain box has been tampered...it happened 2 ma 2004 rav4... When i wanted to scan it was showing Error in Connection. |

As nissparts said,check the fuse. |
Re: My Car Refuses To Be Scanned! by nissparts(m): 3:32pm On Aug 16, 2013 |
OP, did you install any new devices in the car recently? Tracker? Sound system? Remote starter? Immobilizer?.......etc |
Re: My Car Refuses To Be Scanned! by CHIMSKY(m): 2:05pm On Aug 17, 2013 |
nissparts: OP, did you install any new devices in the car recently?Yes.Installed a security system |
Re: My Car Refuses To Be Scanned! by nissparts(m): 4:40pm On Aug 17, 2013 |
That's the source of your issue |
Re: My Car Refuses To Be Scanned! by ZIMDRILL(m): 3:15pm On Aug 18, 2013 |
nissparts: That's the source of your issue i doubt that very much especially if the systems are working independently unless they short wire something during the installation they need to check fuses as well and before installation was the scan able to communicate with car ? |

@OP, look for someone that uses LAUNCH x431-IV scanner, If generic scanners are not getting power from the OBD port. That device has alternative power sources like cigarette lighter, or even direct clips to your battery. If your problem isn't power related, then as @nisspart said, u may have an ECM problem on your hands |
Re: My Car Refuses To Be Scanned! by autofreak2020(m): 11:40am On Aug 19, 2013 |
@mikkyphp, how much is LAUNCH x431-IV auto scanner and where do i get one? |
Re: My Car Refuses To Be Scanned! by mikkyphp(m): 12:54pm On Aug 19, 2013 |
I just got one for a client in mid-july. I can get for you. Price 200k. Price in Nigeria is 300-350k. |
Re: My Car Refuses To Be Scanned! by CHIMSKY(m): 8:33pm On Aug 21, 2013 |
ZIM DRILL:I used to scan the car before myself so i could identify its exact issues and eliminate guesswork. |
Re: My Car Refuses To Be Scanned! by CHIMSKY(m): 8:34pm On Aug 21, 2013 |
viperman:USB Port!Pardon my typo.Have scanned it severak times in the past. |
Re: My Car Refuses To Be Scanned! by sultaan(m): 2:39am On Aug 22, 2013 |
You use to scan it at the USB or OBD port? ![]() The last person to work on your car dis some electrical bubu in there, so the power wire to run the scanner has been cut you other option is to put a battery in your scanner then scan your car. |
Re: My Car Refuses To Be Scanned! by Digriz(m): 8:35pm On Jul 13, 2016 |
Old thread,I resurrected the thread bcus am experiencing the same issue. |
Re: My Car Refuses To Be Scanned! by Nobody: 11:32pm On Jul 13, 2016 |
Digriz:Have you tried begging the car? ![]() What is the name, model & year of your car? |
Re: My Car Refuses To Be Scanned! by Denn(m): 10:12am On Jul 15, 2016 |
ZIMDRILL: CANBUS....if they did 'join-join', many issues could crop up. if diagnostic socket fuse is okay and op has tried other scanners, the possible problems are either wiring faults or ecu fault. |
Re: My Car Refuses To Be Scanned! by honmusa(m): 12:02pm On Jul 15, 2016 |
