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
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?
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 ?
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.
I am a little torn between two modules. The front control module or the cluster.
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:
The following inputs are Received/Monitored by the Front Control Module:
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;
The BCM is operational when battery power is supplied to the module.
The BCM provides the following features:
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.
When replacing a BCM there are three modules available:
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;
Otherwise the appropriate diagnostic procedures for each of the features should be taken when the BCM logs a fault.
Are you saying that I should replace the front control module and/or the cluster?
What would this cost?
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.
