Module Controlled Functions

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.
The SJB is the only multifunction electronic module on this vehicle. The SJB is a combination of a multifunction electronic 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.

Post Crash Alert

The post crash alert function is controlled by the SJB. If the restraints control module (RCM) determines an impact of severity enough to deploy the air bags has occurred (the air bags may or may not be deployed by the RCM), the RCM sends a message to the instrument cluster (IC) over the high speed controller area network (HS-CAN), which sends a message to the SJB over the medium speed controller area network (MS-CAN) and the SJB activates the post crash alert function by sounding the horn 3 times, then off for 4 seconds, then on 3 times, etc, until the battery dies or the function is turned off. The hazard lamps also flash with the horn sounding, however, the hazard lamps keep flashing during the horn off cycle.The post crash alert function can be turned off by:

- pressing the hazard switch (may need to be pressed more than once).
- pressing the integrated keyhead transmitter (IKT) key UNLOCK button.
- pressing the PANIC button.This feature acts similar to a perimeter alarm, but the horn cycle is different. Turning the ignition to the ON position will not deactivate this function, but will deactivate an activated perimeter alarm. This vehicles does not have a perimeter alarm.
The post crash alert function cannot be configured off.
