Conditions for Running the DTC

Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

The DTC will set when the BCM detects a malfunction in the child security door lock switch signal circuit.

Action Taken When the DTC Sets

The indicator will be continuously illuminated.

Circuit/System Verification

Ignition ON, command the Child Security Lock Indicator ON and OFF with a scan tool. The child door lockout indicator should turn ON and OFF while changing between the commanded states.

Circuit/System Testing


1. Ignition OFF, disconnect the harness connector at the S48A Multifunction Switch - Instrument Panel.

2. Connect a test lamp between the control circuit terminal 2 and B+.

3. Ignition ON, command the Child Security Lock Indicator ON and OFF with a scan tool. The test lamp should turn ON and OFF while changing between the commanded states.

4. If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 Body Control Module.

5. If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the K9 Body Control Module.

6. If all circuits test normal, replace S48A Multifunction Switch - Instrument Panel.
