Pinpoint Test C: 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 horn and flashes both the turn signals and courtesy lamps in regular intervals. The BCM receives inputs for the door lock status, hood ajar, door ajar and the keyless entry keypad. 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
- An electronic lock command received from an RKE transmitter, keyless entry keypad, 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 or door is opened, the perimeter alarm arms.
The perimeter alarm is activated when:
- any passenger door or the hood is opened without an electronic unlock command from an RKE transmitter or keyless entry keypad received first.
- the driver door is opened without an unlock command from an RKE transmitter or keyless entry keypad received first and the 12 second countdown has expired.
- the ignition is turned to the RUN position 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
- Turn signals
- Keyless entry keypad concern
- RKE transmitter concern
- BCM

-------------------------------------------------
C1 RETRIEVE THE RECORDED DTCs IN THE BCM
- Retrieve the recorded DTCs from the BCM self-test.
- Is DTC B1305:01 present?
Yes
GO to Pinpoint Test B. Pinpoint Test B: DTC B1305:01
No
GO to C2.
-------------------------------------------------
C2 CHECK THE COURTESY LAMP OPERATION
- Open and close all the doors while checking the courtesy lamp operation.
- Do the courtesy lamps operate correctly?
Yes
GO to C3.
No
REFER to Interior Lighting Testing and Inspection to diagnose the door ajar inputs.
-------------------------------------------------
C3 VERIFY THE HAZARD LAMP OPERATION
- Place the hazard switch in the ON position.
- Do the hazard lamps operate correctly?
Yes
GO to C4.
No
REFER to Exterior Lighting Testing and Inspection to diagnose the hazard lamps.
-------------------------------------------------
C4 CHECK THE RKE TRANSMITTER FUNCTION
- Using the RKE transmitter, lock and unlock the doors and operate the panic function.
- Do the RKE transmitter functions operate correctly?
Yes
GO to C5.
No
REFER to Handles, Locks, Latches and Entry Systems Testing and Inspection to diagnose the RKE function.
-------------------------------------------------
C5 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 C6.
No
REFER to Handles, Locks, Latches and Entry Systems Testing and Inspection to diagnose the keyless entry keypad.
-------------------------------------------------
C6 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 Service and Repair. 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.
