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.
