Circuit/System Verification

Ignition ON, observe the scan tool Exterior Driver Door Handle Switch parameter while pulling and releasing the B27A door handle switch - driver

exterior. The parameter should change between Active and Inactive.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the B27A door handle switch - driver exterior.

2. Ignition ON, verify the scan tool Exterior Driver 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. Connect the a 3 A jumper harness between the signal circuit terminal 2 and ground. Verify the scan tool Exterior Driver Door Handle Switch

parameter is Active.

瀚慖f not the specified value, test the signal circuit terminal 2 for a 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 B27A door handle switch - driver exterior.

Component Testing

Static Test

1. Ignition OFF, disconnect the harness connector at the B27A door handle switch - driver exterior.

2. With the switch in the open position, test for infinite resistance between the signal terminal 2 and the ground terminal 1.

瀚慖f not the specified value, replace the B27A door handle switch - driver exterior.

3. With the switch in the closed position, test for less than 5 ohm between the signal terminal 2 and the ground terminal 1

瀚慖f greater than the specified range, replace the B27A door handle switch - driver exterior.
