Vehicle Demagnetizing

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: During demagnetizing, the demagnetizer coil pulls toward the vehicle. Place a cloth over the roof of the vehicle to protect the vehicle surface if contact occurs. Make sure the cloth covers the front third and the entire width of the roof.
NOTE: The demagnetizing process requires the use of a demagnetizing coil commonly used by television service technicians to demagnetize television tubes.
NOTE: To demagnetize, use a constant circular motion over the roof of the vehicle. Do not turn off the demagnetizer while sweeping the roof of the vehicle to prevent remagnetizing ferrous materials contained in the vehicle.
NOTE: During the demagnetizing process, make sure the phenolic surface of the tool (the side opposite the handle) is closest to the vehicle surface.
  1. Demagnetize the front third of the roof of the vehicle.
    1. Turn on the demagnetizer at least 1 m (3 ft) away from the vehicle.
    2. Holding the demagnetizer no more than 2.5 cm (1 in) from the roof and, starting on the passenger side, demagnetize the front third of the roof closest to the windshield using a constant circular motion. Keep the circle radius within 30 cm (12 in) while sweeping across the entire surface of the roof closest to the windshield. Continue the circular motion 4 times.
    3. After the fourth pass and without stopping, move the demagnetizer at least 1 m (3 ft) away from the vehicle.
    4. Turn the demagnetizer off.
    2. NOTE: The demagnetizer must be located over the outside of the windshield no greater than 2.5 cm (1 in).
  2. Demagnetize the inside rear view mirror mounting pad.
    1. Turn on the demagnetizer at least 1 m (3 ft) away from the vehicle.
    2. Using a circular motion, pass the demagnetizer over the outside of the windshield near the inside rear view mirror mounting pad. Without stopping, move the demagnetizer at least 1 m (3 ft) away from the vehicle.
    3. Turn the demagnetizer off.
  3. Carry out the compass zone adjustment procedure. For additional information, refer to COMPASS ZONE ADJUSTMENT .
  4. Carry out the calibration adjustment procedure. For additional information, refer to COMPASS CALIBRATION .
