If the service engine light comes back on with the same code you have a problem in the wiring between the TCM and the PCM or the TCM itself is bad. CCD is the data bus the computers talk to each other on. For some reason the TCM isn't sending required data to the PCM. I can't find much info on how to troubleshoot. I would say if the wiring shows continuity and the connections are clean and tight, you may need a new TCM. , it appears fixes range from loose connections to replacing entire wire harnesses to bad TCMs. Read a couple that implied bad solder joints on the instrument cluster or replacing the cluster itself fixes it. I'd have to research that a bit.

PCM = Powertrain Control Module <> It's a computer that controls engine functions <> Located on the drivers side fender wall outboard of the battery
TCM = Transmission Control Module <> A computer that controls transmission functions <> Located on the passenger side fender wall

What symptoms are you seeing besides the service engine light?

I have a 1998 Plymouth grand voyager. Code came up on the reader -"P1698 no ccd/j1850 message from tcm/PCM" the speedometer isn't working and it seems to be stuck in 2nd gear. The check engine light is on....

You need a professional to work on it

Test the battery,it may have failed
Check the cables

You have an ECM no CCD message from
the TCM Module

Beyond anything you can do, but use the vehicle
& ruin the transaxle

I have a 2004 Chrysler 300m with a 3.5l engine and getting a 0871 and 0700 code.

Please don't forget to rate!

Trouble Code: P0871 (3.5L V6 VIN G Auto)
A/T O/D Pressure Switch Circuit Malfunction

Trouble Code Conditions:
Engine started; vehicle driven in a forward gear, and the PCM detected that the O/D Pressure Switch circuit indicated open or closed at the wrong time.

Possible Causes:

  • Related DTCs may be present
  • O/D pressure is incorrect, or internal transmission faults exist
  • O/D pressure switch circuit is open, shorted to ground or power
  • O/D pressure switch is damaged or it has failed
  • TCM relay power circuit to O/D switch is open (loss of B+)
  • Intermittent wiring or connector problems exist
  • PCM or TCM has failed

Trouble Code: P0700 (3.5L V6 VIN G Auto)
Automatic Transmission Control System Malfunction

Trouble Code Conditions:
Ignition on or engine started. The PCM received a message over the CCD Bus from the Transmission Control Module (TCM) that it had detected a problem and set a trouble code in memory.

Possible Causes:

  • The presence of this code means the TCM detected a problem
  • TCM related Sensor has solenoid is damaged or has failed
  • This code is for information only - check for other TCM codes
  • TCM or PCM has failed

I have a cherokee sport that is running a few engine codes and i have a code scanner but no book to look the code up... mine are p1281,p0700,p1694

P1281 Engine Is Cold Too Long P1694 No CCD Messages Received From ECM
  • P0700 Transmission Control System Malfunction

    For the P0700 I would check your tps sensor first to make sure it is good. This is a common failure in this vehicle which can sometimes show as a transimission malfunction.

    Hope this helps, if you want alot more info about jeeps goto

    Check engine light is on with code p1698 what is this code

    The code P1698 is: No CCD messages from TCM. That means the communication between the Transmission Control Module and the Power Control Module is lost. Sometimes this happens when a PCM, or TCM is replaced without being flashed, a bad connection at the PCM, TCM, or a bad TCM. Hope this helps.

    A P1698 code is described as PCM Fault, No CCD Messages from TCM Conditions. It's triggered when the key is on, and the PCM did not detect any CCD messages from the Transaxle Control Module (TCM) for 10 seconds. Time for a trip to the dealer unless you feel like inspecting the wires & connectors leading to/from the TCM. Usually I tell people to go to the dealer when there are TCM problems! They can read any codes stored in the TCM that a regular code reader can't get. Good luck.

    Engine check light

    It means that it didn't receive a signal from the transmision module.
    Have your transmission control module checked.

    To reset your engine codes:
    Remove the negative terminal of your battery (10mm wrench).
    Turn your ignition key to START and hold it there for about 15 seconds.
    Turn your ignition key to OFF and remove it.
    Connect the negative terminal of your battery.

    Wont start my odometer blinks and says no bus

    From the official Durango shop manual......(abbreviated)

    Self Diagnosis Test

    Vehicle key position is OFF ,or able to pull key out.
    Hold in the trip odometer button (dont release yet)
    Turn key to the ON position (one notch), but DON'T try to start the engine
    Continue holding the trip button for about 10-12 seconds until CHEC appears in the odometer display
    Release the trip button.
    Series of three digit numeric failure codes may appear.
    If no failure message appears, the self diagnostic test will proceed as described in step 6

    Code Chart

    110- cluster CPU,RAM,EEPROm failure, replace cluster

    900-CCD data bus not operational, check CCD data bus connections at cluster, check the cluster fuses,check the CCD data bus bias, cehck the CCD data bus voltage, check the CCD data bus terminations.

    920-cluster is not recieving a vehicle speed message from the PCM, check PCM software level and reflash if required, use the ($2500+) DRBIII scan tool to verify the vehicle speed message is being sent by the PCM

    921-the cluster is not recieveing a distance pulse message from PCM,check PCM software level and reflash if required, use the ($2500+) DRBIII scan tool to verify the distance pulse message is being sent by the PCM

    940-the cluster is not recieving an airbag lamp-on message from the ACM, check the CCD data bus connections at the ACM, check the ACM fuse.

    950-cluster not recieving an ABS lamp-on message from the CAB, check CCD data bus connections at the ACM, check the ACM fuse.

    960- clsuter not recieving a PRND21 message from the TCM, check the CCD data bus connections at the TCM, check the TCM fuse.

    999-An error has been discovered, record the failure message, depress the trip odometer reset button to continue the Self-Diagnostic Test

    Step 6
    Instrument cluster will test each segment of the odometer (all first, then each one seperately)

    Step 7
    Bulb test

    Step 8
    Gauge test

    Step 9
    test completed

    The instrument cluster will return to normal operation at the completion of test, if ignition switch turned off, or a vehicle speed message indicating movement recieved from the PCM on the CCD data bus.

    Hope that help you or anyone else in future.
