Note 1: After completing repairs of shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Make sure that
ABS warning lamp turns off while driving vehicle at 30 km/h (19 MPH) or more for approximately 1 minute according to self-diagnosis
procedure. In addition, if wheel sensor 2 is displayed for wheels, check wheel sensor circuit and also check control unit power voltage.
Note 2: When malfunctions are detected in several systems, including CAN communication circuit [U1000], troubleshoot CAN communi-
cation circuit. Refer to
BRC-48, "CAN Communication Circuit"
