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 output during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the "Refer to" for the respective "DTC Code" in the DTC chart.
- When 2 or more DTCs are output, 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.
