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 (Smart Junction Box) sounds the horn and flashes the turn signals in regular intervals. The SJB (Smart Junction Box) receives the inputs for the door lock status, hood ajar, liftgate ajar and door ajar over the Medium Speed Controller Area Network (MS-CAN) from the Remote Function Actuator (RFA) module and the Driver Door Module (DDM). The hood switch is also hardwired to the SJB (Smart Junction Box).
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 a Remote Keyless Entry (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 a RKE (Remote Keyless Entry) 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 (Remote Keyless Entry) transmitter concern
- SJB (Smart Junction Box)
PINPOINT TEST D : THE ALARM SYSTEM DOES NOT ARM/NO TURN SIGNAL FLASH CONFIRMATION
D1 RETRIEVE THE RECORDED DTCs IN BOTH THE RFA (Remote Function Actuator) MODULE AND THE SJB (Smart Junction Box)
NOTE: The ignition must be OFF to carry out the RFA (Remote Function Actuator) module self-test.
- Retrieve the recorded DTCs from the RFA (Remote Function Actuator) module and the SJB (Smart Junction Box) self-tests.
Is DTC B1520 or DTC P254F:13 present?
Yes
GO to Pinpoint Test C. Pinpoint Test C: DTC B1520 Or DTC P254F:13
No
GO to D2.
D2 CHECK THE COURTESY LAMP OPERATION
- Open and close all the doors and liftgate while checking the courtesy lamp operation.
Do the courtesy lamps operate correctly?
Yes
GO to D3.
No
REFER to Lighting and Horns.
D3 VERIFY THE HAZARD LAMP OPERATION
- Place the hazard switch in the ON position.
Do the hazard lamps operate correctly?
Yes
GO to D4.
No
REFER to Lighting and Horns.
D4 CHECK THE RKE (Remote Keyless Entry) TRANSMITTER FUNCTION
- Using the RKE (Remote Keyless Entry) transmitter, lock and unlock the doors and operate the panic function.
Does the RKE (Remote Keyless Entry) transmitter functions operate correctly?
Yes
GO to D5.
No
REFER to Doors, Hood and Trunk &/or Locks.
D5 CHECK THE KEYLESS ENTRY KEYPAD FUNCTION
- Lock the doors using the keyless entry keypad.
Do all the doors lock using the keyless entry keypad?
Yes
GO to D6.
No
REFER to Doors, Hood and Trunk &/or Locks.
D6 CHECK FOR CORRECT SJB (Smart Junction Box) OPERATION
- Disconnect all the SJB (Smart Junction Box) connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the SJB (Smart Junction Box) connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new SJB (Smart Junction Box). TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
