Pinpoint Test K: The Smart Unlock Does Not Operate Correctly

Normal Operation

The Smart Junction Box (SJB) automatically unlocks all the doors after the doors are locked with a door lock control switch and the key is in the ignition lock cylinder and one of the front doors is ajar. This feature helps prevent the keys from being locked in the vehicle by unlocking the doors if the key is in the ignition and either front door is ajar.

The vehicle can still be locked with the key in the ignition, by using the manual lock rod, a key in the door lock cylinder, or the LOCK button on a Remote Keyless Entry (RKE) transmitter.

This pinpoint test is intended to diagnose the following:

- Key-in-ignition switch
- Door ajar switch input
- SJB
