recently replaced the rear brakes before the service due date ...now 2 weeks later the lite is on becuase its time for the scheduled service.....the rear brakes are completly done, just need to reset this for the next service interval....Any idea on how to do this....yes i changed the sensor out too.....will this procedure work for the oil changes, microfilter, front brakes, brake fluid ect? email me at pollibr@aol.com
