is displayed
This troubleshooting is carried out when there is still an abnormality, so when disconnecting the
connector and inserting the T-adapter, or when removing the T-adapter and returning the connector
to its original position, if the service code is not displayed, the problem has been removed.
If the abnormality occurs during operation, because of the force of the spring,
1) the engine will run at low idling, or 2) the engine will not stop
If the problem occurs when the engine is stopped,
1) the engine can be started, but it stays in low idling, or 2) it will not stop after it is started.
A Stop the engine (push the governor lever of the fuel injection pump to the NO INJECTION position) before
checking.
* Before carrying out troubleshooting, check that all the related connectors are properly inserted.
* Always connect any disconnected connectors before going on to the next step.
