Circuit/System Verification

1. Ignition ON, observe the scan tool Exterior Left Rear Door Handle Switch parameter while pulling and releasing the B27LR door handle

switch - left rear exterior. The parameter should change between Active and Inactive.

瀚慖f the value is always Inactive or always Active, refer to Left rear Exterior Door Handle Inoperative.

2. Ignition ON, observe the scan tool Exterior Right Rear Door Handle Switch parameter while pulling and releasing the B27RR door handle

switch - right rear exterior. The parameter should change between Active and Inactive.

瀚慖f the value is always Inactive or always Active, refer to Right Rear Exterior Door Handle Inoperative.

Circuit/System Testing

Left Rear Exterior Door Handle Inoperative

1. Ignition OFF, disconnect the harness connector at the B27LR door handle switch-left rear exterior.

2. Ignition ON, verify the scan tool Exterior Left Rear Door Handle Switch parameter is Inactive:

瀚慖f not the specified value, test the signal circuit terminal 2 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 2 and ground. Verify the scan tool Exterior Left Rear Door Handle Switch

parameter is Active.

瀚慖f not the specified value, test the signal circuit terminal 2 for an open/high resistance. If the circuit tests normal, replace the K84 keyless

entry control module.

4. If all circuits test normal, test or replace the B27LR door handle switch-left rear exterior.

Right Rear Exterior Door Handle Inoperative

1. Ignition OFF, disconnect the harness connector at the B27RR door handle switch-right rear exterior.

2. Ignition ON, verify the scan tool Exterior Right Rear Door Handle Switch parameter is Inactive:

瀚慖f not the specified value, test the signal circuit terminal 2 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 2 and ground. Verify the scan tool Exterior Right Rear Door Handle

Switch parameter is Active.

瀚慖f not the specified value, test the signal circuit terminal 2 for an open/high resistance. If the circuit tests normal, replace the K84 keyless
