NOTE: The yaw rate sensor, lateral accelerometer, and longitudinal accelerometer are integral to the accelerometer.

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, on circuit 1577 (RD/LB) and acceleration on circuit 1576 (TN/BK) then sends the signal via SCP communication wires from the ABS module. Voltage is supplied by circuit 1574 (DB). Ground is provided through circuit 1575 (BK WH).

Possible Causes
^ circuit 1574 (DB) open, short to power or ground
^ circuit 1575 (WH/BK) open, short to power or ground
^ circuit 1576 (TN/BK) open, short to power or ground
^ circuit 1577 (RD/LB) open, short to power or ground
^ circuit 1578 (GY/BK) open, short to power or ground
^ circuit 1579 (OG/RD) open, short to power or ground
^ ABS module
^ sensor cluster
