PINPOINT TEST P: THE AUTO-UNLOCK DOES NOT OPERATE CORRECTLY

Normal Operation
The smart junction box (SJB) energizes the unlock relay based upon input from the ajar switches and the vehicle speed signal. The SJB unlocks the doors when the following conditions are met:
- The vehicle speed has exceeded 20 km/h (12 mph) then dropped to 0 km/h (0 mph) (vehicle stopped).
- The key is turned to the OFF or ACCY position.
- The LH front door is opened within 10 minutes of the key being turned to the OFF or ACCY position.

This pinpoint test is intended to diagnose the following:
- Door ajar switches
