Body Control Module: Component Tests and General Diagnostics
Arming Procedure Test
See: Accessories and Optional Equipment Antitheft and Alarm System, descriptions and Operation, Vehicle Theft Security System (VTSS).
See: See Locks, Keyless Entry Transmitter, Service and Repair for programming procedures.
Method - A
1. With the key removed from the ignition lock and any door open, actuate one of the following:
-
Power door lock button to LOCK,
-
Key fob LOCK button
-
Door lock key cylinder to locked position.
2. Close all opened doors.
3. After the last door is closed, an arming time-out period of sixteen seconds will start, then the VTSS will become armed.
Method - B
Actuating the key fob transmitter LOCK button, key locking the front doors or liftgate with the doors closed and the ignition locked will begin the
arming time-out period. If method-A, 16 second time-out sequence was in process when method-B was actuated, the 16 second time-out will
restart from the time of the second actuation.
If the security lamp does not illuminate at all upon final door closure, it indicates that the system is not arming.
The current VTSS status armed or disarmed shall be maintained in memory to prevent battery disconnects from disarming the system.
Diagnostic Notes - Read First
Vehicle Preparation for Testing
Make sure the vehicle being tested has a fully charged battery. If it does not, false diagnostic codes or error messages may occur.
Servicing Sub-Assemblies
Some components of the body system are intended to be serviced in assembly only. Attempting to remove or repair certain system sub-components
may result in personal injury and/or improper system operation. Only those components with approved repair and installation procedures should
be serviced.
Description of On-Board Diagnostics
Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for
determining the cause of trouble codes. It is not necessary to perform all of the tests to diagnose an individual code.
The body control module will set a diagnostic trouble code if a monitored input is determined to be malfunctioning and the trouble condition remains
active for 10 consecutive seconds. Once the trouble condition is removed, the body control module will back out the diagnostic trouble code if the
trouble condition remains cleared for twenty ignition cycles.
Always begin by reading the diagnostic trouble codes using a scan tool. This procedure begins with the Symptom Identification TEST-1A - Identifying
Vehicle Equipment and System Problems. This will direct you to the specific test(s) that must be performed.
