INSPECTION PROCEDURE 3: The Compass is not Correct.

STEP 1. Check the vehicle location
Q: Are there any constructions, such as high-voltage wires or a steel bridge, which might affect the compass sensor?
1. YES: After moving to a location where the magnetic field is stable, check the faulty condition again.
2. NO: Go to Step 2.
STEP 2. Correct magnetization
Q: Was magnetization corrected?
1. YES: Go to Step 3.
2. NO: Correct magnetization. (Refer to VEHICLE MAGNETIC COMPENSATION .)
STEP 3. Correct magnetic declination
Q: Was magnetic declination corrected?
1. YES: Go to Step 4.
2. NO: Correct the magnetic declination. (Refer to ON-VEHICLE SERVICE .)
STEP 4. Demagnetize
Q: Was that demagnetized?
1. YES: Replace the compass sensor.
2. NO: Demagnetize it. (Refer to VEHICLE MAGNETIC COMPENSATION .)
