Failure Switch Test
Remove plug B from module. Connect ohmmeter between pin five (dark green) and pin eight (blue) and check that resistance is less than one ohm (see illustration). Connect ohmmeter between either of pins and ground. Resistance should be infinite. If resistance is not to specifications, check the intermediate connector in engine compartment and failure switch connector at actuator. If connections are all right, check for continuity in wiring harness between failure switch connector and connector B at module. If continuity is correct and failure switch has not been shuttled due to brake release during system cycling, replace actuator.
