GM Trouble Code Info
Accessing 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.

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.
