PINPOINT TEST J: THE PANIC FEATURE IS INOPERATIVE


Test J1-J5:






Normal Operation
The panic function is accomplished by the smart junction box (SJB) receiving a command message from the remote transmitter through the remote transmitter antenna, circuit 2906 (YE/RD) and circuit 2907 (WH/LB). The SJB processes the command and sends a signal activating the alarm and parking lamps.

Possible Causes
- remote transmitter
- SJB
