lobotomy Posted April 7, 2006 Share Posted April 7, 2006 When your engine management light comes on it means something is wrong. Ok so now you need to go out to your car and;Go into the engine bay and open the fuse/diagnostic box (little black box on the left-hand side of the engine bay) And the underside of the lid will show you the pin layout.Bridge pins TE1 and E1 (with a paper clip or bit of wire)Turn ignition on (but don't actually start the car)The engine management light will start to flashIt will flash say 4 times **** then a short pauseIt will then flash say once * This means error code 41 ie. Idle speed probThe management light will then start flashing another error code (they may be more than one fault) or have a short pause and repeat the same code over againThen refer to the list above or the diagram below to see what the error is Quote Link to post Share on other sites
