Vehicle Stability Control System -- Diagnostic Trouble Code Chart |
- HINT:
- 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 "See 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.

- Drive the vehicle at 30 km/h (19 mph) for 60 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.
