DIAGNOSTIC TROUBLE CODE CHART

NOTICE:

Turn the ignition switch off before removing any parts.

HINT:

  • If no malfunction 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 inspection one by one until the problem is identified.
  • Inspect the fuses and relays before inspecting the trouble areas as shown in the following table.
