Steering System DTCS

STEERING SYSTEM DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION

DTC	Description	Action
B1D23	Overheat Sensor	DIAGNOSE any other PSCM DTCs before diagnosing DTC B1D23:68. If no other DTCs are present, INSPECT the EPAS gear heat shield. INSTALL new as necessary. ADVISE the customer that high ambient temperatures and/or heavy loads on the EPAS system will cause this DTC to set, resulting in higher than usual steering effort. A heavy load is defined as multiple parking lot maneuvers over a short duration of time with low tire pressure or towing for long distances followed by multiple parking maneuvers.
C1B00	Steering Angle Sensor	2F GO to PINPOINT TEST E 62 GO to PINPOINT TEST B 64 DIAGNOSE all other PSCM and ABS module DTCs before diagnosing DTC C1B00:64. If no other DTCs are present, CLEAR the DTC and ADVISE the customer certain driving maneuvers may cause this DTC to set resulting in higher than usual torque steer for the remainder of the ignition cycle in which the DTC was set.
C200B	Steering Shaft Torque Sensor 1	2F GO to PINPOINT TEST B 61 GO to PINPOINT TEST B 62 GO to PINPOINT TEST B
C200C	Steering Shaft Torque Sensor 2	GO to PINPOINT TEST B
C200D	Motor Rotation Angle Sensor	INSTALL a new steering gear. REFER to POWER STEERING .
P07AE	Transmission Friction Element G Performance/Stuck Off	GO to PINPOINT TEST F
U0001	High Speed CAN Communications Bus	REFER to MODULE COMMUNICATIONS NETWORK to DIAGNOSE the HS-CAN.
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 the ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) to diagnose the PCM.
U0121	Lost Communication with the Anti-lock Brake System (ABS) Control Module	CARRY OUT an ABS module self-test. If the scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If ABS module DTCs are present, REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL to diagnose the ABS system fault.
U0126	Lost Communication With Steering Angle Sensor Module	CARRY OUT a self test on the SCCM. 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 SCCM, REFER to the DTC list in STEERING COLUMN SWITCHES
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.
U0151	Lost Communication With Restraints Control Module	CARRY OUT a self-test of the RCM. If the scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If RCM DTCs are present, REFER to SUPPLEMENTAL RESTRAINT SYSTEM to diagnose the SRS fault.
U0159	Lost Communication With Parking Assist Control Module A	CLEAR the DTC and CARRY OUT a self-test of the PSCM. If the DTC returns, CARRY OUT self-test of the parking assist control module. 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 parking assist control module, then refer to ACTIVE PARK ASSIST for diagnostic information.
U023A	Lost Communication with Image Processing Module A	CARRY OUT a IPM-A self-test. If the scan tool indicates the module is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If IPM-A DTCs are present, REFER to REAR VIEW MIRRORS .
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 POWER STEERING .
U0401	Invalid Data Received from ECM/PCM A	RETRIEVE and RECORD all PCM DTCs. REFER to the ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) to diagnose the engine speed or vehicle speed concern.
U0415	Invalid Data Received from ABS Control Module	00: RETRIEVE and RECORD all ABS module DTCs. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL to diagnose the ABS and stability control system. 22: RETRIEVE and RECORD all ABS module DTCs. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL to diagnose the ABS and stability control system.
U0428	Invalid Data Received from the Steering Angle Sensor Module	RETRIEVE and RECORD all SCCM DTCs. REFER to STEERING COLUMN SWITCHES to diagnose the SCCM.
U0452	Invalid Data Received From RCM	RETRIEVE and RECORD all RCM DTCs. REFER to SUPPLEMENTAL RESTRAINT SYSTEM to diagnose the lateral acceleration concern.
U045A	Invalid Data Received From Parking Assist Control Module A	RETRIEVE and RECORD all PAM DTCs. REFER to ACTIVE PARK ASSIST to diagnose the PAM.
U053B	Invalid Data Received from Image Processing Module A	RETRIEVE and RECORD all IPM-A DTCs. REFER to REAR VIEW MIRRORS to diagnose the IPMA.
U2011	Motor	49: INSTALL a new steering gear. REFER to POWER STEERING 61: GO to PINPOINT TEST B
U2100	Initial Configuration Not Complete	CHECK the vehicle history for recent service actions related to this module. If there have been recent service actions with this module, REPEAT the PMI procedure as directed by the scan tool or CONFIGURE the PSCM using vehicle as-built data. If there have been no recent service actions, INSTALL a new steering gear to correct the failure to retain configuration data. REFER to POWER STEERING .
U3000	Control Module	41: GO to PINPOINT TEST B 46: GO to PINPOINT TEST B 49: GO to PINPOINT TEST B 61: GO to PINPOINT TEST C 72: GO to PINPOINT TEST D 96: GO to PINPOINT TEST C
U3003	Battery Voltage	16: GO to PINPOINT TEST A 17: GO to PINPOINT TEST A 68: GO to PINPOINT TEST A
