Test H: DTC C1279, C1280, C1281, C1282, C1516, C1517, C2769, C2770, C2777, C2778 - SENSOR CLUSTER FAULT
PINPOINT TEST H: DTC C1279, C1280, C1281, C1282, C1516, C1517, C2769, C2770, C2777, C2778 - SENSOR CLUSTER FAULTNormal Operation
The yaw rate sensor, roll rate sensor, lateral accelerometer and longitudinal accelerometer are contained in the sensor cluster. The sensor cluster measures the vehicle acceleration, roll rate and yaw rate, then sends the signal through the controller area network (CAN) communication wires to the anti-lock brake system (ABS) module.
Voltage is supplied by circuit 1574 (DB). Ground is provided through circuit 1571 (BK). The CAN communication is transmitted through circuit 1878 (WH/BK) and circuit 1879 (PK/BK).
Possible Causes
^ Circuit 1574 (DB) open or short to ground
^ Circuit 1571 (BK) open, short to voltage or short to ground
^ Circuit 1878 (WH/BK) open, short to voltage or short to ground
^ Circuit 1879 (PK/BK) open, short to voltage or short to ground
^ Sensor cluster (also called accelerometer)
^ ABS module
