Stealer says I need a new Body Control Module...Would this go by any other names? I have heard things like Central Timing Module, and Diagnostic Module... WTF? I have a buddy that can hook me up on parts, and I know about taking it in for programming...

Central Timing Module or CTM. It is behind the drivers side kick panel.

Hey Seany B. In this whole thread, you haven't stated what year and model Dakota you have. The name of the module and its location depend on those two pieces of information.

To complete the picture, exactly what does your truck NOT do, that makes your dealership think you need one of these modules?

Wellll....It won't pass SMOG because it sends a Check Engine signal, which they said is an automatic fail, but emissions-wise, it's perfect. Not to mention, ALL gauges stop working intermittently, I have no interior lights, nearly every idiot light on the dash comes on & off, and when I start it, it usually shuts off at least once right after starting, like the security key wasn't used...

Yes, Check Engine light is automatic fail.
Since it sets the Check Engine Light, what codes do you get?

Retrieve codes thusly:
1. ignition switch ON-OFF-ON-OFF-ON (without starting the engine).
2. Codes will display on odometer readout. PDONE means end of list.

Dammit man!
That's a crucial piece of information! If you had noted in the original post, it would have saved all the question and answer crap the last 9 days.
What a dork. Forget it Josh. He evidently doesn't know whats important.

Read this.

"The Programmable Communication Interface or PCI Bus is a single wire multiplexed network capable of supporting binary encoded messages shared between multiple modules. The PCI bus circuit is identified as D25 and is violet with a yellow tracer. Additional tracer colors may be added to the yellow in order to distinguish between different module connections. The modules are wired in parallel. Connections are made in the harness using a splice.
- Airbag Control Module
- Amplifier
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
- Sentry Key Immobilizer Module
- Transfer Case Control Module
Each module provides its own bias and termination in order to transmit and receive messages. The bus voltage is at zero volts when no modules are transmitting and is pulled up to about seven and a half volts when modules are transmitting. The bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only voltage present when the modules transmit and the message length is only about 500 milliseconds, it is ineffective to try and measure the bus activity with a conventional voltmeter. The preferred method is to use the DRBIIIt lab scope. The 12v square wave selection on the 20-volt scale provides a good view of the bus activity. Voltage on the bus should pulse between zero and about seven and a half volts.

The PCI Bus failure modes are broken down into two categories. Complete PCI Bus Communication Failure and individual module no response. Causes of a complete PCI Bus Communication Failure include a short to ground or battery on the PCI circuit. Individual module no response can be caused by an open PCI circuit at the module, or an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to:
- All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display
- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference would be that at least one or more modules would respond to the DRBIIIt.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get a response from the modules with the DRBIIIt. If any modules are responding, the failure is not related to the total bus, but can be caused by one or more modules PCI circuit or power supply and ground circuits. The DRBIIIt may display “BUS +/- SIGNAL OPEN” or “NO RESPONSE” to indicate a communication problem. These same messages will be displayed if the vehicle is not equipped with that particular module. The CCD error message is a default message used by the DRBIIIt and in no way indicates whether or not the PCI bus is operational. The message is only an indication that a module is either not responding or the vehicle is not equipped."


Now you know.

I have a 2002 Dakota and my keyless entry would work intermittenly, I took it to the dealer and purchased a new transmitter, same problem the tech told be that the problem was a BCM that was on a board and that it would cost about $400 to fix. Is there a cheaper fix and is this something I can do myself. What is the failure rate of this module and if found on a recked truck would that module most likely be damaged?

Have a 2001 Dakota with bad Body Control Module, (also called Central Timing Module, Time & Alarm Module). Cheapest one online is aftermarket, $250 plus shipping. I went to a junk yard and found lots of Dodge Dakotas & Durangos, with similar modules, but not the exact same part number. (Similar meaning, in the same location, same pug-ins, and mounting screws) I tried a bunch. Some did fix evertyhing but the power locks would not work (except manually). But some DID work despite not being the same part number. The latest models seemed to have a "learning" function built in. Plugged it in and turned on key, but only heard clicking in the module when I hit the power locks, but after several tries it started working. (Then repeat with key off, and with key out until it works every time). You don't need to remove the bad module to test the new (used) one. Just unplug the three plugs (look for the release tabs and they come out easy) Cost for the part $35-40. Take a flashlight and 8mm wrench with you. That's all you need. The kick panel in the drivers footwell comes out with no tools needed.

I have a 2000 Dodge Dakota Sport, bought it for cheap
because seller said it needed a 'body control module OR
computer' (was told by dodge dealership when brought in). I
ended up changing the Crankshaft Positioning Sensor first to
try it, and it got the truck running but it will stall if no gas is
applied, the RPMs are jumping and when revving it will not go
past 2000rpm, and has a very rough idle while running. I am
having trouble finding the parts needed (body control module
and computer) any suggestions...?
