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

CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.

NOTE: The yaw rate sensor and accelerometer are integral to the sensor cluster. The sensor cluster is not serviceable and must he installed as an assembly.

Normal Operation
The accelerometer (lateral and longitudinal-4x4) 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 ABS module.

Voltage is supplied by circuit 7-CC1 (YE/RD). Ground is provided through circuit 9-CF67 (BN/RD). The CAN communication is transmitted through circuit 8-CF66 (WH/BU) and circuit 9-CF66 (BN/BU).

Possible Causes
^ Power circuit 7-CC1 (YE/RD).
^ Ground circuit 9-CF67 (BN/RD).
^ CAN communication:
- circuit 8-CF66 (WH/BU)
- circuit 9-CF66 (BN/BU)
