EDL shut-off

Electronic Differential Lock (EDL) is deactivated at excessive brake temperature (only EDL).
Standing time (TIM):

The standing time (TIM) is used to calculate how much the brakes have cooled while the ignition is off. The ABS control
module -J104- receives the standing time signal from the instrument cluster.
- If nothing is displayed, press -C- button, select function 02 and check DTC memory. Repair the malfunction with the help
of the DTC table page 01

Output Diagnostic Test Mode (DTM)
(function 03)

Output Diagnostic Test Mode (DTM) is used to
check the function of actuators. Actuators are
also called actors. These are components that
the control module activates when it reacts to the
signals sent by sensors, e.g. solenoid valves,
relays and pump motors.

Note:

Output Diagnostic Test Mode (DTM) only
functions on vehicles containing control
modules with no. 8D0 407 389 A/D/E.
For control modules with no. 4B0 907 389,
output Diagnostic Test Mode (DTM) is not
possible.

Output Diagnostic Test Mode (DTM) can and
must only be selected once after the ignition
is switched on.
