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 sounds the anti-theft horn and flashes the turn signals at regular intervals. The BCM receives inputs for the door lock status, hood ajar, door ajar and the liftgate/luggage compartment lid ajar. The BCM 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)
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 transmitter, the driver door lock cylinder, or an IA 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 transmitter concern
- BCM
PINPOINT TEST D: THE ALARM SYSTEM DOES NOT ARM/NO TURN SIGNAL FLASH CONFIRMATION
-------------------------------------------------
D1 RETRIEVE THE RECORDED DTCs IN THE BCM
- Retrieve the recorded DTCs from the BCM 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 Interior Lighting Testing and Inspection 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 Exterior Lighting Testing and Inspection to diagnose the hazard lamps.
-------------------------------------------------
D4 CHECK THE RKE TRANSMITTER FUNCTION
- Using the RKE transmitter, lock and unlock the doors.
- Do the RKE transmitter functions operate correctly?
Yes
GO to D5.
No
REFER to Handles, Locks, Latches and Entry Systems Testing and Inspection to diagnose the RKE function.
-------------------------------------------------
D5 CHECK FOR CORRECT BCM OPERATION
- Disconnect all the BCM connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the BCM 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. REFER to Multifunction Electronic Modules Body Control Module (BCM). 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.
