INSPECT the RCM for damage. VERIFY that all RCM fasteners are tightened to their correct specification. CLEAR the DTCs. TEST DRIVE the vehicle at speeds above 20 km/h (12 mph). REPEAT the self-test. If DTC C1282 returns, INSTALL a new RCM. REFER to INSTALLATION .
C1288	Pressure Sensor Main/Primary Input Circuit Failure	Go To PINPOINT TEST I .
C1440	Pressure Sensor Main/Primary Signal Faulted	Go To PINPOINT TEST I .
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	CLEAR the DTCs. CYCLE the ignition switch. REPEAT the self-test. RETRIEVE the DTCs. If DTC C1991 is present, INSTALL a new ABS module. REFER to Removal and Installation .
C1996	Active Yaw and/or Roll Control Disabled	Go To PINPOINT TEST J .
C2770	Longitudinal Acceleration Sensor Signal Fault	NOTE: The longitudinal acceleration sensor is integral to the RCM and cannot be serviced separately. If a new longitudinal acceleration sensor is needed, a new RCM must be installed. REFER to Restraints Control Module (RCM) REMOVAL and INSTALLATION . ADHERE to all safety warnings in the procedure. INSPECT the RCM for damage. VERIFY that all RCM fasteners are tightened to their correct specification. CLEAR the DTCs. TEST DRIVE the vehicle at speeds above 20 km/h (12 mph). REPEAT the self-test. If DTC C2770 returns, INSTALL a new RCM. REFER to INSTALLATION .
C2777	Sensor Cluster Bus Failure	Go To PINPOINT TEST G .
U0001	HS-CAN Communication Bus	REFER to MODULE COMMUNICATIONS NETWORK to diagnose the HS-CAN bus.
