Diagnostic Trouble Code Table
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 information for the respective "DTC Code" in the DTC table.
- 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 tables in DTC Check/Clear.
- Inspect the fuses and relays before inspecting the trouble areas as shown in the table below.
