When removing any parts, turn the ignition switch off.
If no abnormality is found when inspecting parts, check the skid control ECU and check for poor contact at ground points.
If a DTC is displayed during the DTC check, check the circuit for the DTC listed in the table below. For details of each DTC, refer to the page indicated.
When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identified.
All DTCs in the table below are detected in accordance with 1 trip detection logic.
