This is in an 87 Regal but since its an Olds engine I'm asking in here...
The SES light has been on, today went to pull the code from the aldl by jumping/grounding the A and B terminals. No flashing code 12 or anything else, lamp just stays lit, manual says to make sure battery voltage is above 11 volts and it is. Checked both ECM 10 amp fuses and both are good. Manual says next is to check voltage/ground terminal C of the SES lamp driver before testing voltage at te ECM. I started taking the panel off to access the ECM, and the glove box door and I was not able to spot this. Is it in the ECM? The manual says it should be near the ecm but i didnt see anything. I didn't have much time to look into anymore than that, had to run to work. If anyone can help me out I'd really appreciate so I can start to fix this tonight after work or early tomorrow morning. Thanks!
