1A-3 Engine General Information and Diagnosis:
For Example:
The ignition switch is turned ON, and the engine stop switch is turned OFF. In this case, the speedometer does not
receive any signal from the ECM, and the panel indicates “CHEC”.
If CHEC is indicated, the LCD does not indicate the trouble code. It is necessary to check the wiring harness between
ECM and speedometer couplers.
The possible cause of this indication is as follows:
Engine stop switch is in OFF position. Side-Stand/ignition inter-lock system is not working. Ignition fuse is burnt.
NOTE
The FI light “B” turns ON about 3 seconds after turning the ignition switch ON.
Dealer Mode
The defective function is memorized in the computer. Use the special tool’s coupler to connect to the mode select
switch. The memorized malfunction code is displayed on LCD (DISPLAY) panel. Malfunction means that the ECM
does not receive signal from the devices. These affected devices are indicated in the code form.
CAUTION
!
Before checking the malfunction code, do not disconnect the ECM coupler.
If the coupler from the ECM is disconnected, the malfunction code memory is erased and the
malfunction code can not be checked.
