Pinpoint Test H: DTC C1279, C1280, C1281, C1282, C2769, C2770 - Sensor Cluster Fault

Normal Operation
The accelerometer (lateral and longitudinal) and the yaw rate sensor are contained in the sensor cluster. The sensor measures the vehicle acceleration and yaw rate then sends the signal via CAN communication wires to the anti-lock brake system (ABS) module.

Voltage is supplied by circuit 7-CC1 (YE/RD). Ground is provided through circuit 9-CF67 (BN/RD). The controller area network (CAN) communication is transmitted through circuit 5-CF66 (BU/WH) and circuit 4-CF66 (GY/VT).

Possible Causes
^ Power circuit 7-CC1 (YE/RD) open, short to ground, or short to power
^ Ground circuit 9-CF67 (BN/RD) open, short to ground, or short to power
^ CAN communication:
- circuit 5-CF66 (BU/WH) open, short to ground, or short to power
- circuit 4-CF66 (GY/VT) open, short to ground, or short to power
