MODULE CONTROLLED FUNCTIONS


NOTE: The smart junction box (SJB) is also known as the generic electronic module (GEM).

NOTE: The time out for the battery saver relay and the accessory delay relay (both are controlled by the SJB) is 1 minute if the vehicle has less than 80 km (50 miles). Once the vehicle passes the approximate mileage threshold of 80 km (50 miles), the time out for both relays will be the normal 10 minute time out, as described by the Owner's Literature. For the battery saver relay, see Pinpoint Test 9: The Battery Saver Does Not Deactivate After Time-Out. For the accessory delay relay, see Pinpoint Test 9: The Delayed Accessory Is Inoperative/Does Not Operate Correctly. Once the vehicle passes the approximate mileage threshold of 80 km (50 miles), the time out for both relays will be the normal 10-minute time out, as described by the Owner's Literature.
The SJB is the only multifunction control module on this vehicle. The SJB is a combination of a multifunction control module and a central junction box (CJB). The following systems are controlled by the SJB:

- Autolocks
- Exterior lamps
- Illuminated entry and interior lamps
- Keyless entry keypad
- Power door locks
- Remote keyless entry (RKE) system
- Tire pressure monitoring system (TPMS)The SJB is located under the front (passenger side floor) console.
