DTC B1474

The passenger front exterior door handle switch signal circuit provides inputs to the keyless entry control module when the passenger front exterior door handle switch is activated. This input allows the keyless entry control module to detect a door open request. The keyless entry control module provides voltage to the passenger front exterior door handle switch via the passenger front door handle switch signal circuit. When the passenger front door handle is activated, the switch closes and the voltage signals from the keyless entry control module are pulled to ground.

Battery voltage is between 9-16 V.

The keyless entry control module detects the passenger front exterior door handle switch signal circuit is short-circuited to ground or closed for more than 60 s.

The keyless entry control module ignores inputs from the passenger front exterior door handle switch.

Ignition ON, observe the scan tool keyless entry control module Exterior Passenger Door Handle Switch parameter while using the passenger door handle. The parameter should change between Active and Inactive.

1. Ignition OFF, disconnect the harness connector at the B27P Door Handle Switch - Passenger Exterior.
2. Ignition ON, verify the scan tool Exterior Passenger Door Handle Switch parameter is Inactive.

⇒	If 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.

⇒	If 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 B27P Door Handle Switch - Passenger Exterior.

Static Test

1. Ignition OFF, disconnect the harness connector at the B27P Door Handle Switch - Passenger Exterior.
2. With the switch in the open position, door handle released, test for infinite resistance between the signal terminal 2 and ground terminal 1.

⇒	If not the specified value, replace the B27P Door Handle Switch - Passenger Exterior.

3. With the switch in the closed position, door handle pulled, test for less than 1 Ω between the signal terminal 2 and ground terminal 1.

⇒	If greater than the specified range, replace the B27P Door Handle Switch - Passenger Exterior.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
