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 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.

U0155	Lost Communication With Instrument Panel Cluster Control Module	REFER to MODULE COMMUNICATIONS NETWORK 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 Cruise-Control Module (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 to diagnose the network communication concern. If C-CM DTCs are present, REFER to COLLISION AVOIDANCE 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 to diagnose the network communication concern. If PSCM DTCs are present, REFER to STEERING SYSTEM - ELECTRONIC POWER ASSIST STEERING (EPAS) 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 to diagnose the network communication concern. If C-CM DTCs are present, REFER to COLLISION AVOIDANCE to diagnose the speed control system fault.
