Note
When removing any parts, turn the ignition switch off.
Tech Tips
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.

Tech Tips
*1: Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed.
Drive the vehicle at 20 km/h (12 mph) for 30 seconds or more and check that the ABS warning light goes off.
Clear the DTC(s).
