VEHICLE STABILITY CONTROL SYSTEM DIAGNOSTIC TROUBLE CODE CHART
Note
Turn the engine switch off before removing any parts.
Tech Tips
-
If no abnormality is found when inspecting parts, inspect the skid control ECU 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 page for 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.

-
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 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 speed of 50 km/h (31 mph) and depress and hold the brake pedal firmly for approximately 3 seconds.
-
Repeat the above operation 3 times or more and check that the ABS warning light goes off.
-
Clear the DTCs.
-
*3:
-
Turn the engine switch on (IG).
