Accessing Trouble Codes

Turn ignition switch to OFF position
Locate the Assembly Line Data Link (ALDL), 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.




12 Pin ALDL

A - Ground
B - Test Terminal
C - Air Injection
E - Serial Data
F - TCC
G - Fuel Pump
H - Brake Sense Speed Input
M - 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. OBDII can also be reset with a scanner.
