Troubleshooting
• Stationary test
Operation tests can be performed while the engine is stopped.
(*1) OCV drive (STBD)
(*2) OCV drive (PORT)
(*3) Operate high-pressure fuel pump
(*4) Operate low-pressure fuel pump
• Data logger
Displays 13 minutes of recorded data for 2 or more of the items stored in the engine ECM. In addi-
tion, the operating time as compared to the engine speed and the total operating time are dis-
played. This enables you to check the operating status of the engine. You can also save the
engine ECM record data to a file so that you can view and display the graph later.
(*1) Intake air pressure
(*2) Engine oil pressure
• ECM record data graph
When a malfunction occurs in the ETV system, 4 seconds (2 seconds before and after the mal-
function) of data is recorded in the engine ECM. This data can be displayed on a graph using the
“ECM record data graph” of the YDIS.
When the communication cable is used to connect a computer to the engine ECM, the engine
ECM record data can be saved and viewed on the computer.
The saved engine ECM record data can also be viewed offline.
