Pinpoint Test D: The Alarm System Does Not Arm/No Turn Signal Flash Confirmation
Normal Operation
The Body Control Module (BCM) controls the perimeter alarm system and based on inputs either arms, disarms or activates the alarm. When the alarm is activated, the BCM (Body Control Module) sounds the anti-theft horn and flashes the turn signals at regular intervals. The BCM (Body Control Module) receives inputs for the door lock status, hood ajar, door ajar and the liftgate/luggage compartment lid ajar. The BCM (Body Control Module) 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/luggage compartment closed
- an electronic lock command received from a Remote Keyless Entry (RKE) transmitter, driver door lock cylinder, or door lock control switch (front door opened and then shut after lock is pressed).
- An Intelligent Access (IA) lock command received (if equipped with IA (Intelligent Access))
Once all the conditions are met, the alarm system enters a pre-arm phase and begins a 11-second countdown. The perimeter alarm arms after 11 seconds have passed and no unlock command is received or any hood, door or liftgate/luggage compartment is opened.
The perimeter alarm is triggered when any door, the hood, or the liftgate/luggage compartment is opened without first receiving an electronic unlock command from a RKE (Remote Keyless Entry) transmitter, the driver door lock cylinder, or an IA (Intelligent Access) unlock. The perimeter alarm also activates if the ignition is turned to RUN without a valid Passive Anti-Theft System (PATS) key read received.
This pinpoint test is intended to diagnose the following:
- Door ajar input
- Hood ajar input
- Liftgate/luggage compartment ajar input
- Turn signals
- RKE (Remote Keyless Entry) transmitter concern
- BCM (Body Control Module)
PINPOINT TEST D : THE ALARM SYSTEM DOES NOT ARM/NO TURN SIGNAL FLASH CONFIRMATION
D1 RETRIEVE THE RECORDED DTCs IN THE BCM (Body Control Module)
- Retrieve the recorded DTCs from the BCM (Body Control Module) self-test.
Is DTC P254F:00 present?
Yes
GO to Pinpoint Test C Pinpoint Test C: DTC P254F:00.
No
GO to D2.
D2 CHECK THE COURTESY LAMP OPERATION
- Open and close all the doors and liftgate/luggage compartment while checking the courtesy lamp operation.
Do the courtesy lamps operate correctly?
Yes
GO to D3.
No
REFER to Lighting and Horns to diagnose the ajar inputs.
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 to diagnose the hazard lamps.
D4 CHECK THE RKE (Remote Keyless Entry) TRANSMITTER FUNCTION
- Using the RKE (Remote Keyless Entry) transmitter, lock and unlock the doors.
Do the RKE (Remote Keyless Entry) transmitter functions operate correctly?
Yes
GO to D5.
No
REFER to Doors, Hood and Trunk &/or Locks to diagnose the RKE (Remote Keyless Entry) function.
D5 CHECK FOR CORRECT BCM (Body Control Module) OPERATION
- Disconnect all the BCM (Body Control Module) connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the BCM (Body Control Module) 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 BCM (Body Control Module). 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.
