C1805	Mismatched PCM and/or ABS-TC Module	CONFIGURE the ABS module using as-built data and correct tire size. REFER to Programmable Module Installation (PMI) in MODULE CONFIGURATION SYSTEM article. CYCLE the ignition switch and REPEAT the self-test. If DTC C1805 is retrieved again, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE in this service information. REPEAT the self-test.
C1956	Steering Angle Sensor Circuit Failure	GO to PINPOINT TEST H .
C1963	Stability Assist Inhibit Warning	NOTE: This DTC will not 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 stability control sensor cluster DTCs before repairing DTC C1963. GO to PINPOINT TEST H .
C1975	IVD Plausibility Failure	REPAIR all other steering wheel angle sensor and stability control sensor cluster DTCs before repairing DTC C1975. GO to PINPOINT TEST H .
U0073	Control Module Communication Bus A Off	REFER to MODULE COMMUNICATIONS NETWORK article 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 article to diagnose the no communication concern.
U0102	Lost Communication With Transfer Case Control Module	REFER to MODULE COMMUNICATIONS NETWORK article to diagnose the no communication concern.
U0104	Lost Communication With Cruise-Control Module (C-CM)	REFER to MODULE COMMUNICATIONS NETWORK article 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 article 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 article 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 article and follow the diagnostics for DTC U0131, Lost Communication with the Power Steering Control Module (PSCM).
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 article to diagnose the no communication concern.
U0405	Invalid Data Received From Cruise-Control Module (C-CM)	This DTC can set due to a fault in the speed control system or because the C-CM is unable to communicate over the High Speed Controller Area Network (HS-CAN) bus. CARRY OUT a self-test of the C-CM. If the scan tool indicates that the C-CM is not responding, REFER to MODULE COMMUNICATIONS NETWORK article to diagnose the network communication concern. If C-CM DTCs are present, REFER to WARNING SYSTEM - COLLISION AVOIDANCE article to diagnose the speed control system fault.
U0420	Invalid Data Received From Power Steering Control Module (PSCM)	This DTC can set due to a fault in the Electronic Power Assist Steering (EPAS) system or because the 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 article to diagnose the network communication concern. If PSCM DTCs are present, REFER to STEERING SYSTEM - ELECTRONIC POWER ASSIST STEERING (EPAS) article to diagnose the EPAS system fault.
U0433	Invalid Data Received From Cruise Control Front Distance Range Sensor	This DTC can set due to a fault in the speed control system or because the C-CM is unable to communicate over the HS-CAN bus. CARRY OUT a self-test of the C-CM. If the scan tool indicates that the C-CM is not responding, REFER to MODULE COMMUNICATIONS NETWORK article to diagnose the network communication concern. If CCM DTCs are present, REFER to WARNING SYSTEM - COLLISION AVOIDANCE article to diagnose the speed control system fault.
