DTC Descriptor

DTC B1474 02: Passenger Exterior Door Handle Switch Circuit Short to Ground

Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
Passenger Door Unlatch Switch Signal	B1474 02	1	1	--
Passenger Door Handle Switch Ground	--	1	--	--
1. Power Door Unlatch Malfunction

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

Conditions for Running the DTC

Battery voltage is between 9-16 V.

Conditions for Setting the DTC

The remote control door lock receiver detects the passenger exterior door handle switch signal circuit is shorted to ground or closed for greater than 60 s.

Action Taken When the DTC Sets

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

Conditions for Clearing the DTC

•	The DTC will be current for as long as the fault is present.

•	When the fault is no longer present, the DTC will be a history DTC.

•	A history DTC will clear after 40 ignition cycles.

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 each time the handle is pulled and released.

Circuit/System Testing

Ignition OFF, disconnect the harness connector at the B27B door handle switch - passenger exterior.
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.

If all circuits test normal, test or replace the B27B door handle switch - passenger exterior.

Component Testing

Passenger Door Handle Switch

Ignition OFF, disconnect the harness connector at the B27B door handle switch - passenger exterior.
With the switch in the open position, test for infinite resistance between the signal terminal 2 and the ground terminal 1.

⇒	If not the specified value, replace the B27B door handle switch - passenger exterior.

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

⇒	If greater than the specified range, replace the B27B door handle switch - passenger exterior.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
