Diagnostic Trouble Code Chart
NOTICE:
When removing any parts, turn the ignition switch off.
HINT:
- If no abnormality is found when inspecting parts, check the skid control ECU and check for poor contact at ground points.
- When 2 or more DTCs are detected, perform each circuit inspection until the problem is identified.
- All DTCs in the table below are detected in accordance with 1 trip detection logic.
