ECU code clear question, YIKES
Did code read, getting codes for 32, 33, 37, and 56. I do the code clear procedure, which turns off the MIL, but when I try to verify the codes are cleared again, they still read in the self-test instead of the MIL blinking steadily (cleared). Can cleared codes still be in the ECU but the MIL be off ?? I used to only get the code 56 until I cleared them the first time, then 32, 33, and 37 came up on the test drive immediately after. Im a pretty good mechanic but the spontaneous addition of the 30's codes has stumped me.

Re: ECU code clear question, YIKES
Disconnect you battery over night and try it again in the morning. It should clear any stored codes.

Re: ECU code clear question, YIKES
Interestingly, after I did the code clear, the MIL has remained off for about 30 minutes of driving. 4 codes just a fluke? Im sure the EGR one will come back but I can live without the others...... The subie ECU is a tricky one

Re: ECU code clear question, YIKES
you have cleared the codes and they have come back that to me doesn't sound like a fluke...It sounds like you possibly have pending codes... have you tried diagnosing any of these codes? one is a speed sensor code and you have two O2 sensor codes.... any driveabilitly concerns? do you know how to test a speed sensor or 02 sensors?
