Output Diagnostic Test Mode (DTM): Notes
NOTE:
- The Output Diagnostic Test Mode (DTM) can only be performed with the engine stopped and the ignition switched on.
- During actuator diagnosis, the individual actuators (with the exception of the injectors) are operated in turn for about one minute unless the next actuator is selected by pressing the > button.
- The control elements can be checked acoustically or by way of touch.
- The Output Diagnostic Test Mode (DTM) is terminated, if after 1 minute actuation time the next control element is not switched to, or the engine is started or an engine speed pulse is detected.
- Before restarting the Output Diagnostic Test Mode (DTM) the engine must be started and the ignition switched off and on again.
The Output Diagnostic Test Mode (DTM) activates the following components in the stated order:
