Diagnostic Aids

WARNING: This page is about a different car, the 2002 Pontiac Aztek and 2002 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

DTC P1380 set indicates that the anti-lock brake system (ABS) has detected a malfunction which will not allow the EBCM/EBTCM to transmit correct rough road data to the PCM. To diagnose this condition, see appropriate ANTI-LOCK/TCS article in BRAKES.
