Tech Tips
If no abnormality is found when inspecting parts, inspect the skid control ECU and ground points for poor contact.
If a trouble code is output during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the "See page" for the respective "DTC Code" in the DTC chart.
When 2 or more DTCs are output, perform circuit inspection one by one until the problem is identified.

*1, *2:
Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed:
*1:
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.
*2:
Keep the vehicle stationary for 5 seconds or more and depress the brake pedal lightly 2 or 3 times.
Drive the vehicle at a vehicle speed of 50 km/h (31 mph) and keep depressing the brake pedal strongly for approximately 3 seconds.
Repeat the above operation 3 times or more and check that the ABS warning light goes off.
Clear the DTC.
Tech Tips
In some cases, the intelligent tester cannot be used when the ABS warning light remains on and the warning message is displayed on the multi-information display.
