System Tests: Notes
If the buzzer/chime unit does not operate as described, perform the following tests to determine if the module is defective or another component is defective. Before starting these tests, the module must be unplugged. DO NOT pull the module out before releasing the locking plastic clip, on the side of the module.
Apply the parking brake. The parking indicator should light. If not, replace the Gauges fuse. If light still does not work, perform voltage and resistance tests.
