DTC

Description

Action

B1342

ECU is Faulted

CLEAR the DTCs. REPEAT the self-test. RETRIEVE the DTCs. If DTC B1342 is retrieved again, INSTALL a new ABS module. REFER to Anti-Lock Brake System (ABS) Module . REPEAT the self-test.

B1596

Service Continuous Codes

The ABS module will disable the self-test for certain DTCs once they are set.

Lost Communication With Power Steering Control Module (PSCM)

NOTE: DTC U0131 is also used for lost communication with the Steering Angle Sensor Module (SASM) on vehicles equipped with Active Park Assist.

DETERMINE whether the vehicle is equipped with Active Park Assist. This can be done by verifying the presence of the Active Park switch located on the center console. If the vehicle is not equipped with Active Park Assist, REFER to MODULE COMMUNICATIONS NETWORK and follow the diagnostics for DTC U0131, Lost Communication with the Power Steering Control Module (PSCM).

If the vehicle is equipped with Active Park Assist, ATTEMPT to communicate with the SASM.

If the scan tool does not communicate with the module, REFER to MODULE COMMUNICATIONS NETWORK and follow the diagnostics for DTC U0126:00, Lost Communication with the Steering Angle Sensor Module (SASM): No Sub Type Information.

If the scan tool does communicate with the module, RETRIEVE and RECORD all SASM DTCs. If there are no DTCs present in the SASM, REFER to MODULE COMMUNICATIONS NETWORK and follow the diagnostics for DTC U0131, Lost Communication with the Power Steering Control Module (PSCM).
