99 Cherokee Sport problem
Have a 99 cherokee sport the airbag light will come on somtimes and stay on for a while, Somtimes when the light is on my gauges will stop working completly. Any one have any suggetions i will take any and all advice.
Its a simple fix its just the conection on the wire harness under the dash. They have directions on the wranglers for this fix a simple slight twist of the prong solves this i belive its a ground issue. Theres a tsp for 4.0 liter engines for the wrangler and the dealer will fix at there expense not sure on cherokee. When this happens to you try bumping underneath the steering wheel and see if it comes back on.
Check your fualt codes it could be a bad clock spring. Also I see the info below...
Safety Recall No. 860
Airbag Control Module
1997-1999 (XJ) Jeep® Cherokee\
Subject
The Airbag Control Module (ACM) on about 390,000 of the above vehicles may corrode internally due to water intrusion. Internal corrosion could cause illumination of the airbag warning light or cause the airbags to deploy without warning. This could injure a front seat occupant if they are out of position or cause an accident without warning.
Repair
The ACM must be replaced and relocated.

TSB NO: 08-15-99
SUBJECT: Erratic, Intermittent Cluster Operation/Intermittent Air Bag Warning light.
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.
OVERVIEW:
This bulletin involves installing a repair harness containing a revised instrument cluster connector.
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®, 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.
