(Note 1): When vehicle was stuck on slippery road, and spin its wheels for Approx. 10 - 80 seconds (the period depends on vehicle
speed). ABS warning lamp may come on. However, this is not abnormal.
(Note 2): Repair short circuit in sensor. ABS warning lamp will come on whenignition switch is turned ON. According to self-diagnosis
operation procedure, drive vehicle at Approx. 30 km/h (19 MPH). Then checkABS warning lamp goes out in about one minute.
