GM OBD/OBD2 Codes

Table of Contents

NOTE: 96 & later are OBD2 systems and require a scanner. For an OBD2 code list, please see our GM code list or the appropriate generic list.

Accessing GM OBD1 Trouble Codes

  • Turn ignition switch to OFF position
  • Locate Data Link Connector (DLC), see image below.
  • Jumper the A&B terminals(a paper clip or a jumper wire work ok)
  • Turn Ignition switch to ON position.
  • Count the flashes on the “CHECK ENGINE” or “SERVICE ENGINE” light.
  • FLASH, pause, FLASH, FLASH = code 12
  • NOTE: Some 94 & 95 models do not have the B terminal. In which case a scanner is required.
  • NOTE: Some 94 & 95 models that DO have the A & B terminals still require a scanner.
  • All vehicles after 96 are OBDII,and require a scanner to access them.
GM Data Link Connector

12 Pin DLC

A – Ground
F – TCC
B – Test Terminal
G – Fuel Pump
C – Air Injection
H – Brake Sense Speed Input
E – Serial Data

Clearing Trouble Codes

  • Diagnostic trouble codes may be cleared by disconnecting the battery ground cable for at least 20 seconds.
  • Reconnect negative battery cable and recheck codes to confirm the repair.

I have a couple that I can’t find one would be a 93 there’s also a 29 and a 05, if you could help me out a little bit with the answers to those three I would be greatly appreciative cuz I’m having a hell of a time figuring out my Roadmaster wagon, it has sat more than I’ve driven it since I got it. When I got it back she don’t run worth a shit once she gets warm. Thanks for reading hope to hear from you

1992 Saturn SL1 SOHC Service Engine Soon light comes on after driving about a mile.
Connecting A & B on diagnostic socket the SES light flashes only Code 12, nothing else.
Everything else seems normal except sometimes speedo flickers up and down, mileage recorder
appears to be running fast and stops at road speed above 40 mph.
Gascap?

These refer to the front airbag system impact sensors, somewhere under the front bumper cover. Probably not disconnected, because otherwise, you’d get a different DTC, but maybe a loose or corroded connection. Any recent bodywork or front impact?
