Note
Turn the ignition switch off before removing any parts.
Tech Tips
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 trouble areas indicated by the DTC. For details of each code, refer to the "See page" for the respective "DTC Code" in the DTC chart.
When 2 or more DTCs are output, perform circuit inspections one by one until the problem is identified.
For DTCs output 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 shown in the table below.
