Normal Operation
The smart junction box (SJB) energizes the lock or unlock relays based upon input from the keyless entry keypad. The keyless entry keypad uses circuits 78 (LB/YE), 121 (YE/BK) and 123 (RD) to send signals to the SJB by grounding the selected circuit through the keyless entry keypad on circuit 1205 (BK). The SJB locks or unlocks the doors and the liftgate (wagon) based on keyless entry keypad input.

Possible Causes
- Circuit 78 (LB/YE) open or short to ground
- Circuit 121 (YE/BK) open or short to ground
- Circuit 123 (RD) open or short to ground
- Circuit 1205 (BK) open
- Keyless entry keypad
- SJB
