Diagnostic Test Mode 2

Diagnostic Test Mode 2

Using DTM 2 it is possible to verify whether certain system components are operating. The test is carried out by activating the components one by one. The control module responds with an acknowledgement code to confirm the activation of a component. In addition to checking the operation of the individual components, this also verifies whether there are breaks or short-circuits in cables or connectors on the component circuitry. DTM 2 is activated with two short presses on the DLC button.

Activating Diagnostic Test Mode 2






- Move the gear selector to position R and set the mode selector to mode S.

- Press twice on the DLC button. The LED starts to blink.

- Activate the components in the order shown in the table below.






NOTE: Certain models: The stop (brake) light switch also sends a signal to the control module. Use "SHIFT- LOCK OVERRIDE" to move the gear shift selector from the P to the R position at operation 2 in the table below.
