Steering System DTCS

POWER STEERING SYSTEM DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTCs	Description	Action
C1023	Pull Drift Compensation Limit Exceeded	GO to PINPOINT TEST T
C102D	High Friction Inside Power Steering	GO to PINPOINT TEST V
U0001	High Speed CAN Communications Bus	REFER to MODULE COMMUNICATIONS NETWORK to DIAGNOSE the high-speed controller area network (HS-CAN) bus.
U0100	Lost Communication with ECM/PCM A	CARRY OUT a self-test of the PCM. If the scan tool indicates that the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If PCM DTCs are present, REFER to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS .
U0126	Lost Communication With Steering Angle Sensor Module	CARRY OUT a self test on the SASM. If the scan tool indicates that the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If DTCs are present in the SASM, REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL for diagnostic information.
U0140	Lost Communication With Body Control Module	CARRY OUT a self-test of the BCM module. If the scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. BCM module DTCs are present, REFER to MULTIFUNCTION ELECTRONIC MODULES to diagnose the BCM system fault.
U0159	Lost Communication With Parking Assist Control Module A	CLEAR the DTCs and CARRY OUT a self-test of the PSCM. If the DTCs return, CARRY OUT a self-test of the PAM. If the scan tool indicates that the PAM is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If DTCs are still present in the PAM, REFER to PARKING AID - AUDIBLE for diagnostic information.
U0300	Internal Control Module Software Incompatibility	RE-FLASH the PSCM software. CLEAR the DTC and REPEAT the self-test. If the DTC returns, INSTALL a new steering gear. REFER to STEERING GEAR
U0415	Invalid Data Received from ABS Control Module	RETRIEVE and RECORD all ABS module DTCs, REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL to DIAGNOSE the vehicle speed signal concern.
U0422	Invalid Data Received from Body Control Module	CARRY OUT a BCM self-test. If the scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to DIAGNOSE the network communication concern. If any DTCs are present in the BCM, REFER to MULTIFUNCTION ELECTRONIC MODULES to DIAGNOSE the BCM system fault.
U0428	Invalid Data Received from the Steering Angle Sensor Module	00: GO to PINPOINT TEST U 62: GO to PINPOINT TEST U
U045A	Invalid Data Received From Parking Assist Control Module A	RETRIEVE and RECORD all PAM DTCs. REFER to PARKING AID - AUDIBLE to diagnose the PAM.
U2100	Initial Configuration Not Complete	CHECK the vehicle history for recent service actions related to the BCM. If there have been recent service actions with the BCM, REPEAT the PMI procedure as directed by the scan tool or CONFIGURE the PSCM using the vehicle as-built data.
U2101	Control Module Configuration Incompatible	00: CHECK the vehicle history for recent service actions related to the BCM. If there have been recent service actions with the BCM, REPEAT the PMI procedure as directed by the scan tool. If there have been no recent service actions REFER to MULTIFUNCTION ELECTRONIC MODULES to DIAGNOSE any BCM concerns. 56: CHECK the vehicle history for recent service actions related to the BCM. If there have been recent service actions with the BCM, REPEAT the PMI procedure as directed by the scan tool. If there have been no recent service actions REFER to MULTIFUNCTION ELECTRONIC MODULES to DIAGNOSE any BCM concerns.
U3000	Control Module	42: CLEAR the DTC and REPEAT the self-test. If the DTC returns, INSTALL a new EPAS gear. REFER to STEERING GEAR 46: GO to PINPOINT TEST B 49: GO to PINPOINT TEST B 53: INSTALL a new EPAS gear. REFER to STEERING GEAR . TEST the system for normal operation. 56: ADDRESS all other PSCM DTCs before progressing. If no other DTCs are present CLEAR this DTC and CYCLE the ignition OFF and ON. REPEAT self-test. 96: GO to PINPOINT TEST C 4B: DIAGNOSE all other PSCM DTCs before addressing this concern. If no other DTCs are present, CHECK and ADJUST the tire pressures as necessary. INSPECT the EPAS heat shield for damage/correct installation and REPAIR as necessary. If the heat shield is undamaged/correctly installed, allow the vehicle to cool down and CLEAR the DTC.
U3003	Battery Voltage	13: GO to PINPOINT TEST A 16: GO to PINPOINT TEST A 17: GO to PINPOINT TEST A 1C: GO to PINPOINT TEST A
