Compass Sensor Module C918
Measure the voltage between the compass sensor module C918 pin 2, circuit 640 (RD/YE), harness side and ground.
Is the voltage greater than 10 volts?
Yes
GO to
B3
.
No
REPAIR the circuit. TEST the system for normal operation.
B3
CHECK CIRCUIT 1205 (BK) FOR OPEN
Measure the resistance between the compass sensor module C918 pin 1, circuit 1205 (BK), harness side and ground.
Is the resistance less than 5 ohms?
Yes
GO to
B4
.
No
REPAIR the circuit. TEST the system for normal operation.

CHECK CIRCUIT 702 (WH/BK) AND CIRCUIT 703 (WH/OG) FOR OPEN AND SHORT TO GROUND
Instrument Cluster C239
Measure the resistance between the compass sensor module C918 pin 3, circuit 703 (WH/OG), harness side and the
instrument cluster C239 pin 13, circuit 703 (WH/OG), harness side; and between the compass sensor module C918 pin
3, circuit 703 (WH/OG), harness side and ground.
Measure the resistance between the compass sensor module C918 pin 4, circuit 702 (WH/BK), harness side and the
instrument cluster C239 pin 12, circuit 702 (WH/BK), harness side; and between the compass sensor module C918 pin 4,
circuit 702 (WH/BK), harness side and ground.
Is the resistance less than 5 ohms between the compass sensor module and the instrument cluster; and
greater than 10,000 ohms between the compass sensor module and ground?
Yes
