engine AUDI A4 1996 B5 / 1.G 01V Transmission Output DTM Workshop Manual

01-164

Output Diagnostic Test Mode (DTM)
(scan tool function 03), transmissions
with hydraulic regulation -E17-


Note:

The Output Diagnostic Test Mode (DTM) can
only be performed when the ignition is switched
off, the selector lever is in position "P", the
engine is not running, and the vehicle is
stationary.
DTM will be terminated when the engine is
started.
The function of solenoid valves 1 -N88-, 2 -N89-
, 3 -N90- and the solenoids for the selector
lever lock are checked acoustically during the
DTM. Avoid noise in the surrounding area
during the acoustic check, because the
switching noise (clicking) of the actuators is
very quiet.
The solenoid valves 4 -N91-, 5 -N92-, 6 -N93-
and 7 -N94- are activated during the DTM. A
direct functional check of these valves is not
possible. But possible electrical faults which
occur during the activation, will be recognized
by the On Board Diagnostic (OBD) and stored
in the DTC memory.

Output Diagnostic Test Mode (DTM)
(scan tool function 03), transmissions
with hydraulic regulation -E18/2-


Note:

The Output Diagnostic Test Mode (DTM) can
only be performed when the ignition is switched
off, the selector lever is in position "P", the
engine is not running, and the vehicle is
stationary.
DTM will be terminated if the engine is
started.
The function of solenoid valves 1 -N88-, 2 -N89-
, 3 -N90- and the solenoids for the shift lock are
checked acoustically during DTM. Avoid noise
in the surrounding area during the acoustic
check, because the switching noise (clicking) of
the final controls is very quiet.
The pressure control valves 1 -N215-, 2 -N216-,
3 -N217- and 4 -N218- are activated during
DTM. A direct functional check of these valves
is not possible. But possible electrical faults
which occur during the activation will be
recognized and stored in DTC memory.
