Diagnostic Trouble Code Chart [08/2013 - ]

NOTE:

Turn the ignition switch off before removing any parts.

HINT:

If no abnormality is found when inspecting parts, inspect the skid control ECU (brake actuator assembly) and ground points for poor connections.
If a trouble code is displayed during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the respective "DTC Code" in the DTC chart.
When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identified.
For DTCs indicated by the warning light or indicator light, refer to the DTC charts in DTC Check/Clear.
Inspect the fuses and relays before inspecting the trouble areas shown in the table below.

DTC

*1 to *3:

Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed:

*1:
1. Drive the vehicle at 20 km/h (12 mph) for 30 seconds or more and check that the ABS warning light goes off.
2. Clear the DTCs.

*2:
1. Turn the ignition switch to ON.
2. Keep the vehicle stationary for 5 seconds or more and depress the brake pedal lightly 2 or 3 times.
3. Drive the vehicle at a speed of 50 km/h (31 mph) and depress and hold the brake pedal firmly for approximately 3 seconds.
4. Repeat the above operation 3 times or more and check that the ABS warning light goes off.
5. Clear the DTCs.

*3:
1. Turn the ignition switch to ON.
2. Depress the brake pedal.
3. Clear the DTCs.
