Control Module References (See: Testing and Inspection/Programming and Relearning) for scan tool information

Circuit/System Verification

1. Ignition ON, observe the scan tool BCM Driver Door Ajar Switch parameter while opening and closing the driver door. The parameter

should change between Active and Inactive.

瀚慖f the value does not change, refer to Driver Door Ajar Switch Malfunction.

2. Observe the scan tool keyless entry control module Driver Door Open Switch parameter while opening and closing the driver door. The

parameter should change between Active and Inactive.

瀚慖f the value does not change, refer to Driver Door Open Switch Malfunction.

3. Observe the scan tool BCM Passenger Door Ajar Switch parameter while opening and closing the passenger door. The parameter should

change between Active and Inactive.

瀚慖f the value does not change, refer to Passenger Door Ajar Switch Malfunction.

4. Observe the scan tool keyless entry control module Passenger Door Open Switch parameter while opening and closing the passenger door.

The parameter should change between Active and Inactive.

瀚慖f the value does not change, refer to Passenger Door Open Switch Malfunction.

Circuit/System Testing

Driver Door Ajar Switch Malfunction

1. Ignition OFF, disconnect the harness connector at the A23D door latch assembly - driver.

2. Test for less than 10 ohm between the ground circuit terminal 8 and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool BCM Driver Door Ajar Switch parameter is Inactive.

瀚慖f not the specified value, test the signal circuit terminal 6 for a short to ground. If the circuit tests normal, replace the M74D window

motor - driver.

4. Install a 3 A fused jumper wire between the signal circuit terminal 6 and ground. Verify the scan tool BCM Driver Door Ajar Switch

parameter is Active.

瀚慖f 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

M74D window motor - driver.

5. If all circuits test normal, test or replace the A23D door latch assembly - driver.

Driver Door Open Switch Malfunction

1. Ignition OFF, disconnect the harness connector at the A23D door latch assembly - driver.

2. Ignition ON, verify the scan tool keyless entry control module Driver Door Open Switch parameter is Inactive.

瀚慖f not the specified value, test the signal circuit terminal 7 for a short to ground. If the circuit tests normal, replace the K84 keyless entry

control module.

3. Install a 3 A fused jumper wire between the signal circuit terminal 7 and ground. Verify the scan tool keyless entry control module Driver

Door Open Switch parameter is Active.

瀚慖f 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

K84 keyless entry control module.
