I wander if these resets are published anywhere.
Perform Service Indicator
Your vehicle will require emissions maintenance at a set interval. To help remind you when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will display “Perform Service”. When the “Perform Service” message is displayed on the EVIC it is necessary to have the emissions maintenance performed. Emissions maintenance includes replacing the Closed Crankcase Ventilation (CCV) filter element, cleaning of the EGR Cooler, and cleaning of the EGR Valve. The procedure for clearing and resetting the "Perform Service" indicator message is located in the appropriate Service Information.
PERFORM SERVICE INDICATOR - RESET
The “Perform Service” message will display on the EVIC each time you turn the ignition switch to the ON/RUN position to indicate a emission maintenance is required. To reset the “Perform Service” indicator system (after performing the scheduled maintenance) refer to the following procedure:
1. Turn the ignition switch to the ON position (Do not start engine).
2. Press and release the brake pedal two times.
3. Fully depress the accelerator pedal slowly two times within 10 seconds.
4. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illumination when you start the vehicle, the “Perform Service” indicator did not reset. If necessary repeat this procedure.
according to the service interval, that light comes on AUTOMATICALLY @ 67500 miles.
