Jeep; Cherokee DESCRIPTION & OPERATION

The Vehicle Theft Alarm (VTA) Module is a logic controlled device that monitors vehicle doors, hood, liftgate and ignition tampering. Alarm activates by sounding horn, flashing all external lights and preventing vehicle engine from running. VTA system arms during normal vehicle lock-up procedure (ignition off, all doors locked with power locks). Security light flashes for 15 seconds during arming process. Security light remains lit during arming process if no signal is received from hood switch.

When the VTA is triggered, horn sounds for 3 minutes while flashing all external lights. Headlights, park and taillights continue to flash for an additional 15 minutes after horn stops. VTA system features a tamper alert function that notifies if vehicle has been tampered with by sounding horn 3 times once a front door is unlocked. The VTA will not arm if door is locked using key or manual lock control.

NOTE: If vehicle battery is disconnected and reconnected, the VTA system enters a power up alarm mode. The headlights, park and taillights will flash. The engine will not run. To exit this mode, the VTA system must be disarmed using key or keyless entry transmitter.

TROUBLE SHOOTING

NOTE: VTA system or VTA system self-test will be inoperative if Powertrain Control Module (PCM), has been replaced within last 20 ignition cycles.

1) System operation may be verified by entering self-test
mode. To enter self-test, cycle ignition key to accessory position
3
times, leaving switch in accessory position. Once in self-test mode,
headlights, park and taillights will begin flashing and horn will
sound twice, verifying their operation.

NOTE: Vehicles equipped with VTA are also equipped with

illuminated entry. Unless illuminated entry system is disabled, it is necessary to wait 30 seconds after each door opening or closure before testing can occur.

2) In self-test mode, horn will sound once after each of the
following tests, indicating proper operation.

  1. Beginning with all doors closed, open and close each
    individual door. The horn will sound each time a door is
    opened or closed. Allow one second between opening and
    closing.

  2. Open, then close hood. Horn will sound upon opening and
    closing hood.

  3. Operate power door locks in both directions.

  4. Rotate key in both door lock cylinders to unlock position.
    Horn will sound as switch closes, and again when it opens.
    Allow at least one second between close and open position.

  5. Cycle ignition switch to RUN position. Horn will sound and
    also take VTA out of self-test mode.

  6. Activate remote keyless entry in both lock and unlock
    directions.


  1. Horn not sounding after any of the above operations
    indicates a switch failure, lack of input signal to VTA module or
    internal failure of module.

  2. Check for continuity at switch. Check for open or shorted
    wire between switch and alarm module. See appropriate wiring diagram
    in the WIRING DIAGRAMS article in the ENGINE PERFORMANCE section.
    Check if PCM has been replaced. When PCM is replaced, it is necessary
    to cycle ignition switch through 20 engine starts to initialize
    system.

  3. Whenever a VTA system malfunction occurs, verify wire
    harness is properly connected to all connectors before starting normal
    diagnosis and repair procedures. If security lamp comes on and remains
    on after ignition is turned on, CCD bus communication signal with PCM
    has been lost.

There are no diagnostic or trouble codes for Vehicle Theft Alarm system. Only symptom diagnosis and repair are provided by the manufacturer.

USING DRB-II

NOTE: Although other scan testers are available, manufacturer recommends using DRB-II (Diagnostic Readout Box II) to diagnose system.

WARNING: DO NOT probe connector with an ohmmeter unless specifically instructed in testing procedure. There is a possibility of air bag deployment.

Ensure DRB-II is connected to CCD data link connector located in behind dash on right side of steering column. See Fig. 9. Ensure correct cartridge is installed in DRB-II for vehicle and system being diagnosed. Menu selections will vary depending on vehicle and system being diagnosed. Follow DRB-II screen prompts to actuate, adjust, monitor, reset, test and diagnose system as necessary.

DRB-II is grounded through CCD data link connector, only one volt-ohmmeter test lead is required when using volt-ohmmeter option. DRB-II volt-ohmmeter should only be used when self-diagnostic tests require the use of this option.

If DRB-II has a blank screen or displays RAM TEST FAILURE, CARTRIDGE ERROR, KEY PAD TEST FAILURE, LOW BATTERY or HIGH BATTERY, this indicates a DRB-II failure. To diagnose and correct these conditions, see BODY CONTROL COMPUTER - VEHICLE COMMUNICATIONS article in ENGINE PERFORMANCE.
