General chaos Posted April 12, 2011 Share Posted April 12, 2011 i have no check engine light that comes on when the key is turned on. possibly a burned out bulb i thought. but then when i looked at the fsm diagrams it shows the check engine light is somehow wired to the tachometer? so is it just my bulb burned out or could there be another problem?

johnceggleston Posted April 12, 2011 Share Posted April 12, 2011 how long have you had the car? if new to you , the seller probably removed the bulb to sell the car. does it run? drive it to a parts store and have the codes read. there may be none, but you don't know until you have them read. or remove the instrument cluster and swap a bulb in from another position just to see if it is on.

General chaos Posted April 12, 2011 Author Share Posted April 12, 2011 i've had the car a long time. probably since 2005. 2006. it has went out. but i talked to a guy today who siad if the computer finds a failure the light will go out. unless he was reading from a 88 book. i can't remember now. that was only an hour ago though. i have soem other test to perform. i will update as i find out if its just the bulb or the ecm.

johnceggleston Posted April 13, 2011 Share Posted April 13, 2011 if the CEL does not come on when you turn the key to ''on'' then it is either burned out or missing. if you can drive the car go have the codes read, if not ''borrow'' a reader.

General chaos Posted April 13, 2011 Author Share Posted April 13, 2011 the car will not start. isnt there a plug to plug together to blink the codes. if the light works? or if the ecm is dead will it turn off the light? i have tried plugging in the two black plugs on th eright side of column. and tunr the key on. i get nothing. i tried the two green ones on the left side of the column and turn the key on and i get nothing.

You aren't listening... When the key is in the on position all the warning lights should come on for a light check to make sure they're working. Every car does this. It's how you tell all the lights are working. You don't have to plug anything together to tell if the lights are working.. Quote Link to comment Share on other sites More sharing options...
General chaos Posted April 13, 2011 Author Share Posted April 13, 2011 no you are not understanding what i am saying. if the bulb is dead it is dead. i want to check the codes doing the u check. i cant do a d check or hook up a code reader i dont have one and no one around here has one for this car. so a u check is what i would like to do. every other light on the dash comes on when they key is turned on. oil airbag the door open light. but no check engine light. the two green plugs have something to do with checking the engine systems or codes. i do know that much.

987687 Posted April 13, 2011 Share Posted April 13, 2011 If it doesn't come on for the light check, how are you expecting to read the codes by using the light?? Replace the bulb. Quote Link to comment Share on other sites More sharing options...
General chaos Posted April 13, 2011 Author Share Posted April 13, 2011 just telll me what plugs i need to plug or unplug. dont change the subject. the answer is simple replace the bulb if its bad. Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted April 13, 2011 Share Posted April 13, 2011 Like everyone else is saying the check engine light should show if you just turn the car to on.. if it does not its missing or blown.. messing with the connectors is not going to do anything at all..

General chaos Posted April 13, 2011 Author Share Posted April 13, 2011 the book says to either unplug or plug in. the connector to get the light to flash to give out the code 11 12 so on. it depends on which book you read. i know the light is suppose to come on. it is probably burnt out. it worked a few days ago. so the answer is pretty obivous if the ecu doenst turn it off.

987687 Posted April 13, 2011 Share Posted April 13, 2011 There's a thread in the repair manual section on the forum for reading codes on your car. You can't read the codes though if the light won't come on. Just sayin' Quote Link to comment Share on other sites More sharing options...

General chaos Posted April 13, 2011 Author Share Posted April 13, 2011 How about listing what kind of car this is. isnt that just a typical screw up. i really thought i posted that i am very sorry. it is a 93 legacy sedan. Quote Link to comment Share on other sites More sharing options...
Durania Posted April 13, 2011 Share Posted April 13, 2011 That is the one omitted key. Plug the two green connectors together under the dash and count the flashes when/if you replace the bulb. A parts store won't be able to pull this code as your car is not OBDII. Quote Link to comment Share on other sites More sharing options...
