Compass: Service and Repair
General Information
In light of the complexity of the compass system and due to the extent of outside influences on its performance, the system should be thoroughly checked
before performing repair service.
The compass system should be checked in an area free from potential interference such as in an open field and calibrated to verify the existence of a
problem.
Should diagnosis lead to the need for replacing the compass sensor module, use the following procedures for removing the module.
