I RECENTLY PURCHASED A 1992 JEEP CHEROKEE AND THE LIGHT THAT SAYS MAINTENANCE DUE IS ON ALL THE TIME. I HAVE CHANGED THE OIL BUT DO NOT KNOW HOW TO RESET THE LIGHT. I HAVE TRIED UNHOOKING BATTERY BUT THAT DID NOT WORK. ANY ADVICE WOULD BE APPRECIATED

THANX

MAINT REQD INDICATOR LIGHT
1991-92 CHEROKEE, COMANCHE & WRANGLER
Vehicles may be equipped with a MAINT REQD on the instrument cluster. This light will come on one time at 82,500 miles to alert driver that emission service is required. At this time, oxygen sensor must be replaced and all other emission components should be inspected, and serviced or replaced as necessary. Chrysler's Diagnostic Readout Box (DRB-II) tester is required to reset the service reminder indicator system.
Using DRB-II tester, access SELECT SYSTEMS. Select appropriate engine. Select with or without A/C. Select FUEL & IGNITION. Select ADJUSTMENTS. Select RESET SRI LIGHT. Reset SRI light. When DRB-II is finished resetting light, DRB-II display will read SRI LIGHT IS RESET.
