Diagnostic Trouble Code Chart

NOTE:

Turn the ignition switch off before removing parts.

HINT:

If no malfunction is found when inspecting parts, inspect the skid control ECU and ground points for poor contact.
If a trouble code is displayed during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to service information 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 investigating the trouble areas as shown in the table below.
