DTC Descriptors
DTC B1534 02
- Left Rear Door Handle Switch Circuit Short to Ground
DTC B1535 02
- Right Rear Door Handle Switch Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
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.
Conditions for Running the DTC
Battery voltage is between 9-16 V.
Conditions for Setting the DTC
B1534 02
The keyless entry control module detects the left rear exterior door handle switch signal circuit is shorted to ground or closed for more than 60 s.
B1535 02
The keyless entry control module detects the right rear exterior door handle switch signal circuit is shorted to ground or closed for more than 60 s.
Action Taken When the DTC Sets
The affect rear door will not open when the exterior rear door handle is pulled unless the door is first unlocked.
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 50 ignition cycles.

Circuit/System Verification
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.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the appropriate B27 Door Handle Switch - Rear.
2. Test for less than 30ohm 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. Install a 3 A fused jumper wire between the signal circuit terminal 2 and ground. Verify the scan tool Exterior Rear Door Handle Switch parameter is Active.
• If not the specified value, test the signal circuit terminal 2 for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K84 keyless entry control module.
5. If all circuits test normal, test or replace the B27 Door Handle Switch - Rear.
Component Testing
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 ohm between the signal terminal 2 and the ground terminal 1
• If greater than the specified range, replace the B27 Door Handle Switch - Rear.
