Diagnostic Test Mode 5

Diagnostic Test Mode 5

Test function 5 continuously reads off values for oil temperature, speed, transmission rpm, transmission and throttle position. The values are continuously updated and shown as flashing codes. These cannot be understood without using the table on the next page. Use the table to convert the code blinks to a reading.

The status of the control module's control of the TP signal and slippage time can also be displayed. The status is read directly from the response codes.

NOTE: The adaptive slippage time function is not yet available as a TCM function. This will be available in the future.

DTM 5 is activated with five short presses on the DLC button.


Activating Diagnostic Test Mode 5






- Ignition ON
- Push the DLC button five times.
