I'm not able to flash/display the SES codes when I ground the ALDL connector.
With the key on, engine off, the light is illuminated, but it doesn't flash when I ground A and B together
Is that indicative of any specific problem? Is there any work around for this? I was going to try to back probe A9 and A12 directly at the ECM and see if that would produce different results.
Appreciate any advice.
Thanks.
