Current software software for 93 lt1? ASR/AST codes
Under 4.0 reads ERR.
Other codes C12, C41, H23, H41, H72.
Trying to find codes for a problem with asr/abs as light comes on. Topped off brake fluid, changed out ebtcm and relays, cleaned connectors and ground. Did not change out pump. Will the pump make any noise at idol ? Had sound deader on top so I assume it to be noisy? I have another pump but was hoping it was in the ebtcm. Since I don't have a hoist it means jacking car up. Being over 70 doesn't help!
