Circuit/System Verification
Ignition ON, observe the scan tool keyless entry control module Exterior Passenger Door Handle Switch parameter while pulling and releasing the
passenger door handle. The parameter should change between Active and Inactive as the handle is pulled and released.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the B27B door handle switch - passenger exterior.
2. Ignition ON, verify the scan tool Exterior Passenger 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 Passenger 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 B27B door handle switch - passenger exterior.
Component Testing
Passenger Door Handle Switch
1. Ignition OFF, disconnect the harness connector at the B27B door handle switch - passenger 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 B27B door handle switch - passenger 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 B27B door handle switch - passenger exterior.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
