Demagnetizing Procedure

WARNING: This page is about a different car, the 2002 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: A magnetic field can adversely affect CMTC compass operation and magnetize the roof panel and forward mounting screw. Magnetized roof panel and overhead console forward mounting screw can be caused by a magnetic base antenna, audio speakers, magnetic signs, etc. Removing magnetic interfering objects will usually restore normal compass operation. If CAL remains displayed on CMTC display and compass display remains blank, roof panel and overhead console forward mounting screw must be demagnetized. Demagnetizing procedure will demagnetize roof panel and overhead console forward mounting screw.
  1. Turn ignition off. Plug Degaussing Tool (6029) into a standard 110/115 volt outlet while keeping the degaussing tool at least 24" (61 cm) away from compass area when plugging tool into outlet. Slowly approach and contact overhead console forward mounting screw with plastic-coated tip of degaussing tool for about 2 seconds. With the degaussing tool still energized, slowly back it away from screw until tip of degaussing tool is about 24" (61 cm) from the overhead console forward mounting screw, then disconnect the degaussing tool.
  2. Place an 8 1/2 by 11" (22 by 28 cm) piece of paper lengthwise from front to rear, on the center line of the roof at the windshield header. The purpose of the paper is to protect roof panel from scratches and define area to be demagnetized. Plug degaussing tool into outlet while keeping the degaussing tool at least 24" (61 cm) away from compass area when plugging tool into outlet.
  3. Slowly approach center of roof panel at windshield header. Contact roof panel with plastic-coated tip of demagnetizing tool. Using slow sweeping motions, and allowing about 1/2" between sweeps, move degaussing tool to each side of roof panel center line about 4" (10 cm). See Fig 1 .
  4. After sweeps are completed, slowly back away from roof panel, with the degaussing tool still energized, until tip of degaussing tool is about 24" (61 cm) from the roof panel, then disconnect the degaussing tool. Calibrate compass and set variance. See COMPASS CALIBRATION  and COMPASS VARIANCE PROCEDURE  under PROGRAMMING.
