Door Open Switch Circuit Test -- Driver

WARNING: This page is about a different car, the 2006 Chevrolet Monte Carlo and 2006 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the (C1 for Coupe) harness connector at the driver door lock.
  2. Test for less than 10 ohms of resistance between the appropriate ground circuit terminal listed below and ground.
    • Base Level Sedan terminal 6
    • Uplevel Sedan terminal 8
    • Coupe terminal D C1
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Driver Door Open Sw. parameter is Closed.
    • If not the specified value, test the appropriate signal circuit terminal listed below for a short to ground. If the circuit tests normal, replace the BCM.
    • Base Level Sedan terminal 5
    • Uplevel Sedan terminal 7
    • Coupe terminal C C1
  4. Install a 3A fused jumper wire between the appropriate signal circuit terminal listed and ground. Verify the scan tool Driver Door Open Sw. parameter is Open.
    • Base Level Sedan terminal 5
    • Uplevel Sedan terminal 7
    • Coupe terminal C C1
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the door lock.
