VEHICLE STABILITY CONTROL SYSTEM DIAGNOSTIC TROUBLE CODE CHART

Note

Turn the engine switch off before removing any parts.

Tech Tips

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 *3:

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 engine switch on (IG).
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.
