VEHICLE STABILITY CONTROL SYSTEM DIAGNOSTIC TROUBLE CODE CHART
Note
Turn the ignition switch to OFF before removing parts.
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 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.
-
Inspect the fuse and relay before investigating the trouble areas as shown in the table below.

(*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 the 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.
