C1282	Lateral Accelerometer Signal Fault	GO to PINPOINT TEST G .
C1288	Pressure Sensor Main/Primary Input Circuit Failure	CLEAR the DTCs. REPEAT the self-test. If DTC C1288 returns, VERIFY all Hydraulic Control Unit (HCU) and ABS module fasteners are tightened to their correct torque specification. If all fasteners are tightened to their correct torque specification, INSTALL a new HCU . REFER to HYDRAULIC CONTROL UNIT (HCU) .
C1440	Pressure Sensor Main/Primary Signal Faulted	CLEAR the DTCs. REPEAT the self-test. If DTC C1440 returns, VERIFY all HCU and ABS module fasteners are tightened to their correct torque specification. If all fasteners are tightened to their correct torque specification, INSTALL a new HCU . REFER to HYDRAULIC CONTROL UNIT (HCU) .
C1470	TCS Function Temporarily Disabled (Thermal Brake Protection)	ALLOW the brake fluid time to cool. CLEAR the DTC. TEST DRIVE the vehicle and VERIFY traction control system operation.
C1805	Mismatched PCM and/or ABS-TC Module	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. NOTE: Repair all other non-communication DTCs before repairing DTC C1963. GO to PINPOINT TEST F .
C1991	Module Calibration Failure	Using the scan tool, CARRY OUT the IVD Initialization sequence. FOLLOW the scan tool directions. CLEAR the DTCs. REPEAT the self-test. If DTC C1991 is retrieved again, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE .
C1996	Active Yaw and/or Roll Control Disabled	GO to PINPOINT TEST I .
C2777	Sensor Cluster Bus Failure	GO to PINPOINT TEST G .
C2778	Sensor Cluster Power Supply Failure	GO to PINPOINT TEST G .
U0001	HS-CAN Communication Bus	REFER to MODULE COMMUNICATIONS NETWORK to diagnose the HS-CAN bus.
U0100	Lost Communication With ECM /PCM	REPAIR all other DTCs first. If DTC U0100 is still present, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the HS-CAN bus.
U0140	Lost Communication with Body Control Module	REPAIR all other DTCs first. If DTC U0140 is still present, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the HS-CAN bus.
U0155	Lost Communication With Instrument Panel Cluster (IPC) Control Module	REPAIR all other DTCs first. If DTC U0155 is still present, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the HS-CAN bus.
U0401	Invalid Data Received From ECM /PCM	If other DTCs are present along with U0401, REPAIR those DTCs first. If U0401 is the only DTC present, CARRY OUT the PCM self-test, RETRIEVE and RECORD any DTCs. REFER to the INTRODUCTION - GASOLINE MODELS to diagnose the PCM.
U1901	CAN Network #2 Communication Bus Fault	GO to PINPOINT TEST G .
U2050	No Application Present	CLEAR the DTCs. CARRY OUT the self-test, RETRIEVE and RECORD any DTCs. If DTC U2050 is retrieved again, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . CLEAR the DTCs. REPEAT the self-test.
