TROUBLESHOOTING, FRONT GEARCASE
(ADC)
Customer Complaint: ADC not functioning

Verification of complaint: Drive vehicle with ADC switched on and off down a grade if possible to determine if ADC
(Auto-lock is working correctly). May need to be in low range to tell in high traction areas. Make sure switch on handle
bar is on ADC mode. Make sure ADC light is lit on gage pod. Vehicle must be in hi, low, or reverse. Also, vehicle
throttle lever must be off. If complaint is warranted, move onto component check list. If no, move onto other vehicle
components (suspension, driveline, engine, etc.) Vehicle may also be tested in air. All 4 wheels need to be off ground,
put into ADC mode and roll back wheels if possible. Rotate cover side front wheel forward and back, should feel roll
cage in front drive index and lock the front wheel to the drive line. This can only be done on the cover side wheel. It is
also best to make sure 4x4 is not engaged any more. This way is possible to test but best way is to ride vehicle down
steep hill as stated above.
