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.
- If a trouble code is displayed during the DTC check, inspect the trouble areas listed for that code. For details of the code, refer to "See page" below.
- 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.
