OK: Go to next step.

CALIBRATE COMPASS
1. Perform calibration (See CALIBRATION ).
- NG: Go to step 3
- OK: NORMAL

CHECK WIRE HARNESS (MAGNETIC FIELD SENSOR - COMBINATION METER ASSY)

Disconnect the M6 sensor connector.
Disconnect the C9 meter connector.

Measure the resistance of the wire harness side connectors.
