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 there is a disconnection in the solenoid or wiring harness, the solenoid is not actuated.
If the No. 2 pin of the solenoid is short circuiting with the ground, the solenoid continues to be actuated.
If the starting switch is turned OFF after an abnormality occurs, turn the starting switch ON, operate according
to Condition 2 in Table 1, and check if any service code is displayed. (If it is not displayed, the problem has
been removed.)
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.
Check that fuse 1 is normal.
