If you are an IPD subscriber (parts whse) a number of the models/years can be reset without tools. (www.ipdusa.com)
1993-1995 can be reset without tools.
1996 - 1998 require a reset tool. IPD may sell this - not sure.
1999 - 2000 can be reset via following a few steps (no tools)
Instructions for 1999-2000:
1. turn the ignition switch to position 1 (off)
2. Only the SRS indicator light is illuminated on the dash panel.
3. This is a two handed process: while pressing the trip mileage reset button,
turn ignition swith to position 2 (II). The service light will begin to flash in
15 - 30 seconds. as soon as it flahes release the reset button.
4. Turn ignition switch off. The service lamp should now be reset.
If doesn't work (which I found works everytime) go through all steps again. Swede in Colorado
