Demagnetize Compass

WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

Possible Causes are:

  1. A blank compass display indicates that vehicle demagnetizing is required. After demagnetizing, the vehicle will enter Auto Fast-Cal when the ignition is turned on. Ensure that the correct compass variance is stored in the compass memory. See SETTING MAGNETIC ZONE VARIANCE  under COMPASS in PROGRAMMING.
  2. Perform Demagnetizing Procedure. See COMPASS DEMAGNITIZING  under SERVICING. When demagnetizing procedure is complete, perform the Verification Test. See BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
