Door Lock Switch Signal Test
NOTE:
Ensure power door lock harness and connector circuits are okay before testing door lock switch signal. See appropriate chart under POWER DOOR LOCK CONTROL RELAY/INTEGRATION RELAY CIRCUIT TESTING charts.
- Locate power door lock control relay. Ensure control relay 16-pin connector is connected. Using voltmeter positive lead, backprobe Blue/Red wire terminal of connector. Using voltmeter negative lead, backprobe Blue/White wire terminal of connector.
- Ensure voltage increases from zero to battery voltage for approximately 0.2 second with door lock manual switch in UNLOCK position. Reverse voltmeter leads and ensure voltage increases from zero to battery voltage for approximately 0.2 second with door lock manual switch in LOCK position. If voltage does not change as specified, replace power door lock control relay and retest system.
