PINPOINT TEST M: THE AUTOLOCK DOES NOT OPERATE CORRECTLY

Normal Operation
When autolock is enabled the SJB requires the following inputs:
- Digital transmission range (TR) sensor
- Door ajar switches (all doors closed)
- Ignition switch position
- Vehicle speed

The vehicle speed and TR sensor inputs are received through the communications network. Once the SJB receives all 4 inputs the doors automatically lock.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door ajar switches
- Ignition switch
- Vehicle speed signal
- SJB
