| Post subject: | Engine Fault Codes |
I'm sure I've seen a list of these on the Forum somewhere, but can't find them. Can anyone point me in the right direction? Also, can they be read without specialised equipment, and how is the ECU reset? Thanks in advance..... |

By the way though........ Resetting the ECU will not remove the Error codes that you may have......... They'll still come back........... Anyone correct that if its wrong.....

It will prob clear the error codes, but the ECU will detect them and they will re-occur... |

You can check with an LED and paper clip, I'll post details if any ones interested, maybe a good sticky post. I'm not sure if you can read codes with a LED on all engine management systems though. I know you can read 2 digit DTC's but not sure about 4 digit ones

i'm definitely interested. I want to cure the bouncing rpm problem that my car has. and the first thing i want to do is check for any trouble code that it may be giving out. cheers gj |

forgive my ignorance, but would resseting the ecu make any diff to the engine, or will it stay the same |

do you mean [1] clearing the trouble codes or [2] resetting the ECU to some factory default? i would think that [1] would not do anything to the engine. but i can't say anything about [2]. I don't even know how [2] can de done. may be someone more knowledgeable can enlighten us. cheers gj |
