ELECTRONICALLY CONTROLLED BRAKE SYSTEM DIAGNOSTIC TROUBLE CODE CHART

Note

When replacing the skid control ECU, sensor, etc., make sure that the power switch is turned off, the stop light switch is off, and 2 minutes have elapsed since the driver's door was closed.

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 displayed during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the page for the respective "DTC Code" in the DTC chart.
When 2 or more DTCs are detected, perform circuit inspections one by one until the problem is identified.
Inspect the fuses and relays before inspecting the trouble areas as shown in the table below.
