ABS Module

ABS MODULE DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION

DTC Description Action
B1342 ECU is Faulted CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. 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 This DTC is only an indicator that other DTCs are present. This DTC sets after clearing DTCs with the scan tool. An ignition cycle from OFF to RUN is required to set this DTC as a Continuous Memory Diagnostic Trouble Code (CMDTC) which allows the ABS module to check for other on-demand DTCs. CLEAR the DTCs. CYCLE the ignition switch. RETRIEVE the DTCs. CLEAR the DTCs again. REPEAT the self-test.
B1676 Battery Pack Voltage Out of Range GO to PINPOINT TEST A .
B2477 Module Configuration Failure CONFIGURE the ABS module using as-built data and correct tire size. REFER to Programmable Module Installation (PMI) in MODULE CONFIGURATION . CYCLE the ignition switch and REPEAT the self test. If DTC B2477 is retrieved again, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . REPEAT the self-test.
B2900 VIN Mismatched GO to PINPOINT TEST F .
C1145 Wheel Speed Sensor RF Input Circuit Failure GO to PINPOINT TEST B .
C1155 Wheel Speed Sensor LF Input Circuit Failure GO to PINPOINT TEST B .
C1165 Wheel Speed Sensor RR Input Circuit Failure GO to PINPOINT TEST B .
C1175 Wheel Speed Sensor LR Input Circuit Failure GO to PINPOINT TEST B .
C1222 Wheel Speed Sensor Mismatch GO to PINPOINT TEST C .
C1266 ABS Valve Power Relay Circuit Failure GO to PINPOINT TEST D .
C1278 Steering Wheel Angle 1 and 2 Signal Faulted GO to PINPOINT TEST H .
C1280 Yaw Rate Sensor Signal Fault GO to PINPOINT TEST I .
C1282 Lateral Accelerometer Signal Fault GO to PINPOINT TEST I .
C1288 Pressure Transducer Main/Primary Input Circuit Failure GO to PINPOINT TEST J .
C1296 Wheel Speed LF Signal Fault GO to PINPOINT TEST C .
C1297 Wheel Speed RF Signal Fault GO to PINPOINT TEST C .
C1298 Wheel Speed RR Signal Fault GO to PINPOINT TEST C .
C1299 Wheel Speed LR Signal Fault GO to PINPOINT TEST C .
C1300 ABS Hydraulic Pump Motor Circuit Failure GO to PINPOINT TEST E .
C1440 Pressure Transducer Main/Primary Signal Faulted GO to PINPOINT TEST J .
C1446 Brake ON/OFF Plausibility Fault(s) GO to PINPOINT TEST J .
C1516 Roll Rate Sensor Signal Fault GO to PINPOINT TEST I .
C1805 Mismatched PCM and/or ABS-TC Module GO to PINPOINT TEST F .
C1956 Steering Angle Sensor Circuit Failure GO to PINPOINT TEST H .
C1963 Stability Assist Inhibit Warning
NOTE: This DTC won't clear until the vehicle has been driven above 48 km/h (30 mph) with input from the steering wheel rotation sensor.
REPAIR all other steering wheel angle sensor and RCM DTCs before repairing DTC C1963. GO to PINPOINT TEST H .
C1975 IVD Plausibility Failure REPAIR all other steering wheel angle sensor and RCM DTCs before repairing DTC C1975. GO to PINPOINT TEST H .
C2770 Longitudinal Acceleration Sensor Signal Fault GO to PINPOINT TEST I .
U0073 Control Module Communication Bus A Off REFER to MODULE COMMUNICATIONS NETWORK to diagnose the no communication concern.
U0074 Control Module Communication Bus B Off GO to PINPOINT TEST I .
U0100 Lost Communication With Engine Control Module (ECM)/PCM REFER to MODULE COMMUNICATIONS NETWORK to diagnose the no communication concern.
U0102 Lost Communication With Transfer Case Control Module REFER to MODULE COMMUNICATIONS NETWORK to diagnose the no communication concern.
U0131 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 SASM follow the diagnostics for DTC U0126:00. TEST the system for normal operation.
U0151 Lost Communication With Restraints Control Module (RCM) GO to PINPOINT TEST I .
U0155 Lost Communication With Instrument Panel Cluster Control Module REFER to MODULE COMMUNICATIONS NETWORK to diagnose the no communication concern.
U0428 Invalid Data Received From Steering Angle Sensor Module (Power Steering Control Module [PSCM]) This DTC can set due to a fault in the Electronic Power Assist Steering (EPAS) system or because the Power Steering Control Module (PSCM) is unable to communicate over the HS-CAN bus. CARRY OUT a self-test of the PSCM. If the scan tool indicates that the PSCM is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the no communication concern. If PSCM DTCs are present, REFER to STEERING SYSTEM - ELECTRONIC POWER ASSIST STEERING (EPAS) to diagnose the EPAS system fault.
U0452 Invalid Data Received From Restraints Control Module GO to PINPOINT TEST I .
U2023 Fault Received From External Node This DTC indicates that other communication "U-codes" are present in the module. DIAGNOSE and REPAIR all other U-codes. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
U2050 No Application Present CONFIGURE the ABS module using as-built data. REFER to Programmable Module Installation (PMI) Using the Integrated Diagnostic System (IDS) When the Original Module is Not Available in MODULE CONFIGURATION . CLEAR the DTCs. REPEAT the self-test.
