Speedo/Airbg light

What does it mean when I am driving down the road with my 1999 XJ and my Speedo stops and the airbag light comes on. Then about 2mins later it goes back to normal. This is the first time this has gone on, PLEASE HELP:doh:

Go visit your local Jeep dealer. Chrysler has a service bulletin about replacing one of the instrument cluster connectors. I had to do it to my own, my father's, and numerous others. It is TSB #08-15-99 (below). :thumbup:
-------------------------------------------------------------------------
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

POLICY: Reimbursable within the provisions of the warranty.

FAILURE CODE: P8 - New Part

Thank

Thank you very much, OZTRUCKS

We have the exact same issue with my sons 99' XJ, it sounds like the fix in the TSB is to cut in a new connector? Do you think it would be possible to clean the contacts, add a little anti oxidant compound to get by with the old one for a while?
