PINPOINT TEST D: THE AUTOLOCK DOES NOT OPERATE CORRECTLY

D1-D2:

D3-D4:

Normal Operation
When autolock is enabled the smart junction box (SJB) requires the following inputs:
- the digital transmission range (TR) sensor
- the stoplamp switch
- the door ajar switches (all doors closed)

The stoplamp switch and TR sensor inputs are received through the communications network. Once the SJB receives all 3 inputs the doors automatically lock.

Possible Causes
- circuitry
- door ajar switches
- SJB
