18. IGNITION SYSTEM
SERVICE INFORMATION
GENERAL SAFETY
Inspect the ignition system in proper sequence based on the troubleshooting.
Dropping or giving a shock to the ECU unit causes a trouble.
There should be battery voltage with the ignition and engine stop switched ON. Turn the main switch
OFF while serving.
TRANSISTOR ignition system is used and it can not be adjusted.
Couplers are connected to other couplers which have same colour.
Coil standard resistance may not be obtained due to the different measuring circumatances.
A faulty ignition system is often related to poorly connected connectors. Check those connections before proceeding.
This manual gives explanations on inspections to receive peak voltage. As inspections for coil resistance values are also
included, it may be difficult to make a correct determination.
Conduct inspection on the main switch by referring to the wiring diagram continuity chart. (⇨chapter 21-1 )
