DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
Turn the ignition switch off before removing any parts.
HINT:
- If no malfunction 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, inspect the trouble areas listed for that code. For details, refer to the "See page" reference for the DTC.
- When 2 or more DTCs are detected, perform diagnosis for each DTC, one by one until the problem is identified.
- If DTCs were checked using the warning light or indicator light, refer to the tables in DTC Check/Clear to cross-reference them to the 5-digit DTCs shown in the following tables.

*1 to *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 30 km/h (12 mph) for 30 seconds or more and check that the ABS warning light goes off.
- Clear the DTCs.
*2:
- Turn the ignition switch to ON.
- 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 depress and hold the brake pedal firmly for approximately 3 seconds.
- Clear the DTCs.
