Diagnostic Fault Information





Circuit/System Description

When the driver door is unlocked with a key, the tamper switch closes. This grounds the door's input to the remote control door lock receiver (RCDLR). The system is then disarmed and the alarm state will not become active when the door is opened.

The remote control door lock receiver is an internal part of the RCDLR for the remote keyless entry (RKE) system. When the RCDLR receives a valid key transmission from the remote transmitter, it unlocks the doors. Therefore the RCDLR recognizes this in the same manner as a valid door lock switch disarm input.

Circuit/System Testing

1. Ignition OFF, disconnect the X2 harness connector at the driver door latch assembly.
2. Test for less than 1 ohm between the ground circuit terminal listed below and ground.

* Terminal C (RHD)
* Terminal B (LHD)

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

3. Ignition OFF, disconnect the harness connector at the RCDLR.
4. Install a 3A fused jumper wire between the appropriate door latch signal circuit terminal listed below and ground.

* Terminal A (RHD)
* Terminal D (LHD)

5. Test for less than 1 ohm between the signal circuit terminal 12 and ground.

• If greater than the specified range, test the signal circuit for an open/high resistance. If the circuit tests normal, test or replace the drivers door latch.

6. If all circuits test normal, test or replace the RCDLR.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.

* Door Lock Cylinder Replacement (Service and Repair)
* Control Module References (Programming and Relearning) for RCDLR replacement, setup, and programming
