Jeep Instrument Cluster

Q. My son has a 1998 Jeep Cherokee with 47,000 miles. It has the 4.0 liter engine with auto transmission. The problem is sometimes the instrument cluster shuts off. It can be reset at times with the trip odometer button.

Sometimes it is just the tach and speedometer, other times it includes the other gauges. These episodes start with the air bag light coming on.

Thanks,
Ken

A. Chrysler issued a TSB, number 08-15-99 on May 21, 1999 about this problem. I quote from the bulletin:

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.

So have your son bring it to Chrysler and they will fix it at no charge since he is still in warranty.
