Parking Brake Switch
The switch used for the parking brake is a normally open switch that is located under the steering tower cover (Fig. 26). When the parking brake is not applied, the parking brake pawl depresses the switch plunger to close the switch. When the parking brake is applied, the parking brake pawl is positioned away from the switch plunger so the switch is in its normal, open state.
Testing
1.Make sure the engine is off. Locate parking brake switch for testing.
2.Disconnect wire harness connector from the switch.
3.Check the continuity of the switch by connecting a multimeter (ohms setting) across the connector termi- nals.
4.When the switch plunger is extended there should not be continuity between the switch terminals.
5.When the switch plunger is depressed, there should be continuity between the switch terminals.
6.After testing, connect switch connector to wire har- ness.
