ECU Service Menu

The ECU Service Menu is used when the ECU Service Tool needs to be used to communicate with the Engine ECU for troubleshooting.

First enter the ECU Service Menu on the SG+ 1.5 Controller. You will get the following messages:

  • ECU SERVICE MODE

  • ENGINE OFF

  • CONTROLLER ON

  • ECU ON

The ECU Service Tool is software that is independent of the SG+ 1.5 Controller and is a program with is opened on your PC. This software tool comes in a Diagnostic kit which is called Yanmar Smart Assist Direct (YSAD). Use the Yanmar SmartAssist Direct (YSAD) Diagnostic Tool to determine what DTC Codes are set. For corrective actions, refer to the Yanmar Troubleshooting Guide. See the “Yanmar YSAD Diagnostic Engine Service” chapter.
