Diagnostic Test




1. MEASURE THE RESISTANCE OF THE DOOR UNLOCK SWITCH SENSE CIRCUIT

Turn the ignition off.
Disconnect the BCM harness connector.
Disconnect the SKREEM harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance of the Door Unlock Switch Sense circuit from the BCM harness connector to the SKREEM harness connector.

Q: Is the resistance below 5.0 ohms?

YES: Go to 2
NO: Repair the Door Unlock Switch Sense circuit for an open. Perform VTSS VERIFICATION TEST. VTSS Verification Test




2. MEASURE THE VOLTAGE OF THE DOOR UNLOCK SWITCH SENSE CIRCUIT

Turn the ignition on.
Measure the voltage of the Door Unlock Switch Sense circuit at the SKREEM harness connector.

Q: Is voltage present?

YES: Repair the Door Unlock Switch Sense circuit for a short to voltage. Perform VTSS VERIFICATION TEST. VTSS Verification Test
NO: Go to 3




3. MEASURE THE RESISTANCE OF THE DOOR UNLOCK SWITCH SENSE CIRCUIT

Turn the ignition off.
Measure the resistance between ground and the Door Unlock Switch Sense circuit at the SKREEM harness connector.

Q: Is the resistance below 10K ohms?

YES:Repair the Door Unlock Switch Sense circuit for a short to ground. Perform VTSS VERIFICATION TEST. VTSS Verification Test
NO: Replace the Sentry Key Remote Entry Module. Perform VTSS VERIFICATION TEST. VTSS Verification Test
