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.
  1. Locate integration relay in instrument panel junction block No. 1. Ensure integration relay 12-pin connector "A" and 8-pin connector "B" is connected. Using voltmeter positive lead, backprobe connector "B" terminal No. 2 (Blue/White wire). Using voltmeter negative lead, backprobe connector "B" terminal No. 3 (Black/Yellow wire). Ensure voltage increases from zero to battery voltage for approximately 0.2 second with door lock manual switch in UNLOCK position.
  2. 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 integration relay and retest system.
