Test J: The Autolock Does Not Operate Correctly

PINPOINT TEST J: THE AUTOLOCK DOES NOT OPERATE CORRECTLY

Normal Operation
When autolock is enabled, the vehicle security module (VSM) locks the doors when the following conditions are met:

NOTE: The autolock feature is not available on vehicles equipped with a manual transmission.
- All the doors are closed
- The ignition switch is in the ON position
- The vehicle is shifted into any gear putting the vehicle in motion
- The brake pedal is released and the vehicle attains a speed greater than 8 km/h (5 mph)

The VSM receives the brake pedal position (BPP) switch, transmission range (TR) sensor and the vehicle speed signal (VSS) inputs from the instrument cluster (IC) through the universal asynchronous receiver-transmitter (UART)-based protocol (UBP) communications network.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door ajar switch input
- UBP communications network
- VSM
