    Odometer says: "no bu5" 99 TJ 4.0

    I have a 99 Wrangler 4.0 manual. Yesterday, the tach and speedo quit, about 15 seconds later the Check Engine and Airbag light would come on, and the odometer display would read: no bu5 I think it was trying to read
    "no bus".

    It was intermittent- usually it would read for a minute after a dead stop, or turning the Jeep off and restarting it, then go dead again. A tap on the dash also seemed to make it work for a few seconds.

    Seems like a loose connection, and I'm wondering if anyone could tell me where to start looking. The Jeep runs fine, no problems, so I'm guessing it might just be a connector to the dash instrmentation or something?

    there is a TSB on that. The electrical connector at the back of the IP has terminals that don't have enough pin tension. dcx has a repair kit for it.

    NUMBER: 08-15-99

    GROUP: Electrical

    DATE: May 21, 1999

    THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN NUMBER 08-20-98 REV. A, DATED OCTOBER 2, 1998, WHICH SHOULD BE REMOVED FROM YOUR FILES AND NOTED IN THE BOUND TECHNICAL SERVICE BULLETIN BOOK, PUBLICATION NUMBER 81-699-99003. THIS IS A COMPLETE REVISION TO THE PROCEDURE.

    SUBJECT:
    Erratic, Intermittent Cluster Operation/Intermittent Air Bag Warning light.

    OVERVIEW:
    This bulletin involves installing a repair harness containing a revised instrument cluster connector.

    MODELS:

    1998 - 1999 (TJ) Wrangler
    1998 - 1999 (XJ) Cherokee

    SYMPTOM/CONDITION:
    Some vehicles may exhibit an intermittent illumination of the air bag warning light or an intermittent tachometer or speedometer drop out. An Airbag Electronic Control Module (AECM) fault code - "No Cluster CCD BUS" message will be present.

    DIAGNOSIS:
    Using the DRB III(R), read and record all active and stored fault codes in the AECM. This condition is caused by minor oxidation of the BUS circuit terminals at the instrument cluster connector. Electrical terminals will show signs of oxidation, which will appear as darkened lines or marks on the cluster male terminals. These often appear as gray or black marks rather than the appearance of oxidation or corrosion usually associated with higher current carrying circuits. This condition will set a "NO CLUSTER CCD BUS" message. The fault code will usually be stored and not active. THIS TECHNICAL SERVICE BULLETIN WILL NOT ADDRESS FUEL OR OIL PRESSURE GAUGE ISSUES. If this fault code is present, either active or stored perform the Repair Procedure.

    PARTS REQUIRED:

    1 05016261AA Cluster Connector Patch Harness
    1 04856975 Electric Contact Cleaner
    2 04778570 Heat Shrink Tubing
    ASE Master Tech

    So take it to the dealer and let them fix at no charge?

    Thanks for the info! I was thinking you'd know what it was. Much appreciated, Digger.

    I had the same problem and fixed it myself in about 10 minutes.

    Pull the instrument cluster, clean the connections really good with contact cleaner, apply generous amounts of dielectric grease. Put everything back together. Done.

    No problems for me for the last 6 months since I did this.

    Free if it's under warranty. A TSB is not a recall. Just a service bulletin issued for techs to be aware of several vehicles with the same problem

    I had a bad PCM, but yours definitely sounds like bad connectors behind the cluster. You can either clean the contacts as newracer suggests, or you can go purchase the new style connector from DC (1 05016261AA Cluster Connector Patch Harness) for less than $15 and install it yourself.

    The good news is that the cluster comes out of a TJ really easily. Eleven philips head screws and you're in.

    Nice! Thanks for the price heads up- I can swing the $15, and be done with it.

    Here is a pretty good write up on how to remove the cluster and what to clean.
