Diagnostic Trouble Code Chart
NOTE:
Turn the ignition switch off before removing any parts.
HINT:
- If no abnormality is found when inspecting parts, inspect the skid control ECU and ground points for poor connections.
- 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 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.
- For DTCs indicated by the warning light or indicator light, refer to the DTC charts in DTC Check/Clear.
- Inspect the fuses and relays before inspecting the trouble areas as shown in the table below.
