The self-diagnosis function is incorporated in the ECM. It can be notified by using the FI indicator light assy (option).
To check the function of the individual FI system devices, the dealer mode is provided. In this check, the tool is
necessary to read the DTC (Diagnostic Trouble Code) that identify malfunction location.
Dealer mode
Connect the FI indicator light assy (1) to the dealer mode coupler. The DTC is displayed by flashing pattern of FI
indicator light when turning on the ignition switch. This means that the ECM has not received signals indicating a
correct condition from the sensors or device concerned.
