DTC B1534 or B1535

The left and right rear exterior door handle switch signal circuits provide inputs to the keyless entry control module when the rear exterior door handle switches are activated. These inputs allow the keyless entry control module to detect a rear door open request. The keyless entry control module provides a signal voltage to each rear exterior door handle switch via the left and right rear door handle switch signal circuits. When a rear 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.

B1534 02

The keyless entry control module detects the left rear exterior door handle switch signal circuit is shorted to ground or closed for greater than 60 seconds.

B1535 02

The keyless entry control module detects the right rear exterior door handle switch signal circuit is shorted to ground or closed for greater than 60 seconds.

The affected rear door will not open when the exterior rear door handle is pulled unless the door is first unlocked.

The affected exterior rear door handle will fail to trigger an unlock command of a locked vehicle.

Control Module References for scan tool information

Ignition ON, observe the scan tool keyless entry control module Exterior Left Rear Door Handle Switch or Exterior Right Rear Door Handle Switch parameters while using the rear door handles. The value for each should change between Active and Inactive.

1. Ignition OFF, disconnect the harness connector at the appropriate B27 Door Handle Switch - Rear.
2. Test for less than 30 Ω between the ground circuit terminal 1 and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool Exterior Rear 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.

4. If all circuits test normal, test or replace the B27 Door Handle Switch - Rear.

Static Test

1. Ignition OFF, disconnect the harness connector at the appropriate B27 Door Handle Switch - Rear.
2. 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 B27 Door Handle Switch - Rear.

3. 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 B27 Door Handle Switch - Rear.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
