Customer Question

DASH LIGHTS FLICKER. INSTALLED NEW BATTERY- RAN GOOD FOR 2 MONTHS. NOW FLICKERING AGAIN. RED LIGHTS APPEAR WHEN CAR IS RUNNING, RADIO SHUTS DOWN - THIS ALL TAKES PLACE WITH-IN A SECOND. VAN HAS STOPPED TWICE. THEN IT CAN BE RESTARTED. DODGE GRAND CARAVAN 2005.

Is the engine running OK, or is it trying to stall?
Customer: replied 5 years ago.

Engine is running OK.

I have disconnected the battery cable and reconnected. It seems that the dash lights reset. It is then OK for a few hours then the slight flickering begins. It gets worse. The dash seems to shut down with lights and bells going off. Radio stops also.Because it is only a split second engine keeps running.

 

Engine has also shut down when stopped at a light. It will start up OK.

 

Had brought car to the dealer. Could find nothing wrong.

Said that the battery could be causing it. Replaced battery and all ran fine for a few months.

 

Someone said it could be a short in aternator. Thanks, Erik

You need to have the voltage checked at the battery, when this acts up.
Customer: replied 5 years ago.

voltage has been checked - OK.

All electrical systems have been checked - OK.

 

When dash lights begin to flicker, I turn car off, then restart and it runs fine for a while.

When it happens again, I turn car off and restart.

Thanks - so what's the deal with this?

Expert:  jeepmopar76 replied 5 years ago.
I never heard o f this one; I'll opt out, so someone else can look at your problem.

HelloCustomer

 

There maybe two possible modules causing your issue. From what you describe the bus network of the van is going down. what bothers me is you state the engine stalls.

When the engine stalls, are the dash and radio acting up ?

Customer: replied 5 years ago.

Again - Van runs OK. Then at some point the dash lights start to flicker. It may get worse or go away. When it gets worse all the red lights come on, dask indicators go to max, radio shuts down, head lights shut down, bells ring, all this while van is still running. This process takes about 1 to 2 seconds.

 

 

When I stop the van and shut down and then restart all the lights come on, gages go go to max, bells ring (speed shows 120 mph, tack to max) then it all "resets" and all is normal for a while.

 

Van has only shut down twice and this at idle speed. Van will start up immediatedly and go through the cycle mentioned above.

 

Thanks

Erik

Thank you,

 

I am a little torn between two modules. The front control module or the cluster.

 

 

 

OPERATION

As messages are sent over the Programmable Communications Interface (PCI) data bus, the Front Control Module (FCM) reads these messages and controls power to some of the vehicles electrical systems by completing the circuit to ground (low side driver) or completing the circuit to 12 volt power (high side driver).

The following functions are controlled by the Front Control Module:

  • Accessory Relay Actuation
  • Brake Transmission Shift Interlock Functions (BTSI - gas engine only)
  • Diesel Cabin Heater (Diesel Engine Vehicles)
  • Electronic Back Light (EBL) Rear Defogger
  • Front and Rear Blower Motor Relay Actuation
  • Front Fog Lamp Relay Actuation
  • Washer Motor (front and rear)
  • Front Windshield Wiper "HI" & "LO" Relay Actuation
  • Front Windshield Wiper "ON" Relay Actuation
  • Headlamp Power with Voltage Regulation
  • Horn Relay Actuation
  • Headlamp Washer Relay Actuation (IF EQUIPPED - EXPORT ONLY)
  • Name Brand Speaker (NBS) Relay Actuation
  • Park Lamp Relay Actuation

The following inputs are Received/Monitored by the Front Control Module:

  • Ambient Temperature Sensing
  • Back-Up switch
  • Brake Fluid Level
  • B+ Connection Detection
  • Engine Crank Signal (Diesel Engine Vehicles)
  • Horn Input
  • Ignition Switch Start Only
  • Ignition Switch Run and Start Only
  • Stop Lamp Sense
  • Washer Fluid Level
  • Windshield Wiper Park
  • OPERATION

    The Body Control Module (BCM) supplies vehicle occupants with visual and audible information and controls various vehicle functions. To provide and receive information, the BCM is interfaced to the vehicle's serial bus communications network, referred to as the Programmable Communications Interface (PCI) bus.

    This network consists of the;

    • Powertrain Control Module (PCM)
    • Transmission Control Module (TCM)
    • Mechanical Instrument Cluster (MIC)
    • Occupant Restraint Controller (ORC)
    • Compass/Mini-Trip Computer (CMTC)
    • Electronic Vehicle Information Center (EVIC)
    • Controller Antilock Brake (CAB)
    • HVAC Control Module
    • Sliding Door Control Modules (driver and passenger side doors)
    • Power Liftgate Module (PLG)
    • Audio system equipped with RAZ, RBU, RBK, and RBB radios.
    • Sentry Key Remote Entry Module (SKREEM).
    • Side Impact Airbag Control Module (SIACM)
    • Memory Seat Module (MSM)
    • Sentry Key Immobilizer Module (SKIM)

    The BCM is operational when battery power is supplied to the module.

    The BCM provides the following features:

    • Power Door Locks
    • Automatic Door Locks
    • Battery Protection - The BCM will automatically turn off all exterior lamps after 3 minutes, and all interior lamps after 15 minutes after the ignition is turned off, if they are not turned off by the driver.
    • Chime Control
    • Compass/Mini-Trip support.
    • Interior Lighting (Courtesy/Reading Lamps)
    • BCM Diagnostic Reporting
    • Electronic Liftgate Release (with Power Door Locks)
    • Exterior Lighting
    • Headlamp Time Delay (with/without Automatic Headlamps)
    • Illuminated Entry
    • Fade to Off Interior Lamps - This feature dims the interior lighting (courtesy lamps) gradually if the BCM does not receive any new inputs that would cause the interior lamps to remain on.
    • Pulse Width Modulated Instrument Panel Dimming
    • Door Lock Inhibit - This feature disables the door lock functions if the key is in the ignition and either front door is ajar. Pressing the Remote Keyless Entry (RKE) lock/unlock button under these conditions result in normal lock/unlock activation.

    The BCM has the ability to LEARN additional features in the vehicle, provided the appropriate switch input and PCI data bus messages are received. Refer to the LEARNED FEATURES table.

    LEARNED FEATURES

    FEATURE LEARNING KEY
    REAR WIPER CONTROL ON HVAC CONTROL ON INSTRUMENT PANEL PCI BUS MESSAGE RECEIVED FROM HVAC CONTROL
    AUTOMATIC HEADLAMPS PCI MESSAGE FROM OVERHEAD OR HEADLAMP SWITCH POSITION (AUTO)
    REMOTE KEYLESS ENTRY SKREEM MESSAGE RECEIVED FROM MODULE
    FRONT FOG LAMPS HEADLAMP SWITCH POSITION (PARK W/FRONT FOG LAMPS)
    POWER SLIDING DOOR PCI IFR RECEIVED FROM MODULE
    THE BCM HAS FOUR SWITCH INPUTS FOR THE POWER SLIDING DOOR FEATURE; LOCATED IN THE OVERHEAD CONSOLE ARE THE LEFT AND RIGHT SIDE SLIDING DOOR SWITCHES TO ACTIVATE EITHER OR BOTH SLIDING DOORS UNDER THE PROPER CONDITIONS. ALSO ARE B-PILLAR SWITCHES LOCATED ON THE LEFT AND RIGHT B-PILLAR POSTS.
    POWER LIFTGATE PCI IFR RECEIVED FROM MODULE
    THE BCM HAS ONE LIFTGATE INPUT LOCATED IN THE OVERHEAD CONSOLE.
    POWER LOCKOUT SWITCH INPUT
    THE BCM HAS ONE LOCKOUT SWITCH INPUT THAT WHEN ENABLED WILL DISABLE THE B-PILLAR SLIDING DOOR SWITCHES FROM ACTIVATING EITHER SLIDING DOOR WHEN DEPRESSED.
    PCI AUDIO SYSTEM PCI MESSAGE RECEIVED FROM MODULE
    REMOTE RADIO CONTROLS REMOTE RADIO SWITCHES PRESENT
    VEHICLE THEFT SECURITY SKREEM MESSAGE RECEIVED, VALID KEY RECEIVED, & DIAGNOSTIC PID RECEIVED.
    MEMORY SEAT AND MIRRORS MEMORY SEAT SWITCH PRESENT AND OR PCI MESSAGE RECEIVED FROM MEMORY MODULE
    ABS W/TRACTION CONTROL PCI MESSAGE RECEIVED FROM CAB
    SENTRY KEY IMMOBILIZER SYSTEM PCI MESSAGE RECEIVED FROM SKIM OR VTSS PRESENT
    ADJUSTABLE PEDAL MODULE PCI MESSAGE RECEIVED FROM ADJUSTABLE PEDAL MODULE (APM)

    When replacing a BCM there are three modules available:

    • Base
    • Midline
    • RG - Export

    The Midline controller is used on vehicles that have Power Door Locks. If a vehicle is equipped with the Vehicle Theft Security System, the Midline controller becomes a Premium when the theft feature is enabled.

    CAUTION: Do not swap Body Control Modules between vehicles or body controller's off the shelf.

    The BCM has internal diagnostic capability that assists in diagnosing the system error. When an OPEN or a SHORT circuit exists, the diagnostic tool can be used to read the BCM faults. The faults are very descriptive in identifying the appropriate feature that has faulted.

    The only two faults that the BCM logs that conclude the replacement of a BCM are faults;

    • # XXXXX - Internal BCM failure (replace BCM)
    • # XXXXX - J1850 Internal Hardware Failure (replace BCM)

    Otherwise the appropriate diagnostic procedures for each of the features should be taken when the BCM logs a fault.

Customer: replied 5 years ago.

 

Are you saying that I should replace the front control module and/or the cluster?

What would this cost?

Thanks

Erik

Expert:  Instructor jp replied 5 years ago.

You need a factory scan tool to be sure at best. Just throwing parts will not work well and with that said I know you have been to the dealer. It may be best if you locate another dealer with better results. You will need a factory scan tool in the hands of someone who can understand what they are looking at. I'm sorry but I do not want you just replacing parts with no fix. If you feel you want to go with one or the other module after the van is looked at, I would feel better about the front control module being replaced as the vehicle has stalled during the cluster fall out. Of coarse you may have a problem with both pieces. Both of the modules will need to be installed by a dealer. They will need to be programed and personalized to your van.
