I not with the vehicle now...I'm at work... When I get home I will get you the vin.. the PCM and BCM that was installed or supposed to be new

Can you tell me why your replacing both of them?

Ask Your Own Chrysler Question

This may help:

SYMPTOM/CONDITION:

Vehicle does not run (engine starts and stalls) or improper theft alarm actuation occurs after swapping Powertrain Control Module (PCM) or Body Control Module (BCM) between non-Vehicle Theft Security System (VTSS) and VTSS equipped vehicles.

DISCUSSION:

The VTSS function on LH vehicles resides in the PCM and BCM. The PCM module becomes programmed to support VTSS when it is installed on a vehicle that has VTSS enabled in the BCM. The PCM and BCM carry this information with them if they are transported from one vehicle to another. When a PCM is put into a vehicle in which the BCM has VTSS enabled, the PCM will ‘learn’ that the vehicle has VTSS after the ignition is turned on. Installing a VTSS enabled module in a non-VTSS equipped vehicle or vise versa will cause a no-start condition or improper theft alarm actuation.

NOTE: TO PREVENT NO-START CONDITIONS DUE TO VTSS BEING ENABLED ON A NON VTSS VEHICLE, PCMs AND BCMs ON LH VEHICLES MUST NOT BE EXCHANGED BETWEEN VEHICLES OR INSTALLED IN VEHICLES AND THEN RETURNED TO THE PARTS DEPARTMENT.

REPAIR PROCEDURE:

This repair involves disabling VTSS on a vehicle which has been enabled incorrectly.

NOTE: THE ENTIRE PROCEDURE MUST BE DONE WITH THE BATTERY DISCONNECTED TO AVOID CONTAMINATING THE NEW MODULES.

NOTE: USE THE DRBIII® SCAN TOOL TO REPROGRAM THE NEW PCM WITH THE VEHICLES ORIGINAL IDENTIFICATION NUMBER (VIN). IF THIS STEP IS NOT DONE A DIAGNOSTIC TROUBLE CODE (DTC) MAY BE SET.

THE VEHICLE MILEAGE IS STORED IN THE BCM ON LH VEHICLES. ORDERS FOR BCMs WITH THE CORRECT VEHICLE MILEAGE CAN ONLY BE PLACED THRU THE SERVICE CENTER

  1. Remove both the PCM and BCM as described on pages 8D-10 and 8E-6 of the 1998 Concorde/Intrepid Service Manual
  2. Replace the PCM and the BCM with non-VTSS enabled modules.
  3. Verify the repair was successful by cycling the ignition on and leaving it in the run position for a minimum of 30 seconds, then cycle the ignition off, remove the key from the ignition, open the drivers door, lock the vehicle via the power door locks and close alldoors. After waiting two minutes, unlock the vehicle manually using the key (do not use the remote keyless entry FOB) and open a door. The alarm should not sound and the vehicle should start and run normally.

I have a 1998 Chrysler Concorde 3.2...I replace the PCM and BCM a few years back..becuase of the no start stall out issue. I took it to the dealership and was told it could be my camshaft position sensor or my PCM or PCM or all three... I have the dealership replace the PCM and BCM... And I still have the same issue
Customer reply replied 4 months ago
I would have to replace both PCM and BCM with a non vtss version of both ?
Customer reply replied 4 months ago
If so how do I find or know the PCM and BCM are non vtss ?

I will need your VIN to see if your vehicle is equipped with VTSS first...

Ok
Customer reply replied 4 months ago
Ok vin is 2c3hd46j9whi95331

Ok your Bright Platinum 1998 LH is equipped with security sales code LSA. The BCM part number is ***** and the PCM is R4896120AE. Are these the part numbers they installed? If yes then you will need a DRBIII scantool to verify the correct VIN was installed and to see if the VTSS is enabled...

Customer reply replied 4 months ago
I need to take it to the dealership for the drb3 scan to check those...
Customer reply replied 4 months ago
Is there anyway to bypass the vtss system at all...
Customer reply replied 4 months ago
Be cause at first the car would crank run for 2 seconds then die now the key won't even get the car to turn over all the lights on instrument panels come on but the car doesn't even attempt to try to turn over

The security system has it locked out... The DRBIII will be required to scan the BCM..

StanSayre, PA

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT. NO LUNGING FORWARD, THE TURBO REACTS THE SECOND I STOMP ON THE GAS, AND IT HAS A LOT MORE POWER AND EVEN SOUNDS BETTER TO ME. IT SAVED ABOUT $500.00 BY DOING THE WORK MYSELF. I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
