DCM Operation History [08/2019 - ]

HINT: 

• This function shows the telematics network status when the DCM (telematics transceiver) was operated. Use this when no DTC is present but this telematics system was unable to connect to the call center. This symptom may occur if cell phone signal strength is very weak.
• This function is used to display operation history information and the time at which it was stored in the DCM (telematics transceiver).

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Choose "Telematics" from the System Selection Menu, and then click "Utility".
5. Click "DCM Operation History" on the Utility Selection Menu.
6. Choose "Items" on the DCM Operation History Menu.

   HINT: 

   • When "Operation Code" is recorded, DCM Operation History is displayed on the Techstream.
   • The displayed "Function" differs depending on the selected "Items".
7. Refer to the following chart and check the system operation status displayed on the Techstream. (The following chart is an example of the system operation status.)
