Pinpoint Test D: The Alarm System Does Not Arm/No Turn Signal Flash Confirmation
Normal Operation
The Smart Junction Box (SJB) controls the perimeter alarm system and based on inputs, either arms, disarms or triggers the alarm. When the alarm is triggered, the SJB sounds the horn and flashes the turn signals in regular intervals. The SJB receives inputs for the door lock status, hood ajar, liftgate ajar, door ajar, and the keyless entry keypad. The SJB also receives signals from the Remote Keyless Entry (RKE) transmitters.
For the perimeter alarm to arm and provide a flash of the turn signals, the following conditions must be met:
- Ignition must be OFF
- The hood closed
- All doors closed
- The liftgate closed
- An electronic lock command received from an RKE transmitter, keyless entry keypad, driver door lock cylinder, or door lock control switch (front door opened and then shut after lock is pressed).
Once all the conditions are met, the alarm system enters a pre-arm phase and begins a 20-second countdown. After 20 seconds have passed and no unlock command is received or any hood, door or liftgate is opened, the perimeter alarm arms.
The perimeter alarm is triggered when any door, the hood, or the liftgate is opened without an electronic unlock command from an RKE transmitter, keyless entry keypad or the driver door lock cylinder is received first.
This pinpoint test is intended to diagnose the following:
- Door ajar input
- Hood ajar input
- Liftgate ajar input
- Turn signals
- Keyless entry keypad concern
- RKE transmitter concern
- SJB
