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.
