recognised via message on CAN network

-

No noticeable system limitation

-

Automatic mode available

3199

No CAN message received from ABS/EBS unit
due to:
-

communication problem with ABS/EBS

-

shifted to the neutral position

-

driving off from a stationary position is not
possible

-

system is not available

2.1 GENERAL

If the tyre size is changed or if the vehicle is

adjusted in such a way that the configuration is

changed, the electronic unit may have to be re-

programmed.

2.2 'TRANSMISSION' MENU

The 'Transmission' menu is subdivided into two

tests:

-

static selector shaft position test

-

dynamic selector shaft position test

Both tests are used to check the mechanical

operation of the AS Tronic gearbox. This is done

by reading the position of all selector shafts in

gears that have been determined beforehand.

These positions are shown on the DAVIE display

by means of a position value, the so-called INC

(increment). Upon the start of both tests the

accessory test report needs to be printed. The

measured position values should be incorporated

in the test report, so that the mechanical

operation of the gearbox can be evaluated.

Static selector shaft position test
This test is carried out with a stationary vehicle

and running engine. Using the "+" and "-" buttons

on the DAVIE display the gearbox can be shifted

up and down respectively. Changing between RL

and RH is done by means of button "Reverse

gears". In this way the desired gears of the

relevant test report can be selected. Per selected

gear the measured position values can be

compared with the correct position values that

are stated between brackets in the test report.

Dynamic selector shaft position test
If no appreciable deviations are found in the static

selector shaft position test, the dynamic selector

shaft position test can be carried out

subsequently. This test is carried out while driving

with a loaded gearbox. Again, the accessory test

report should be printed (both test reports are

identical, however the test conditions differ).

While driving, the desired gears of the relevant

test report can be selected using the operating

unit. Per selected gear the measured position

values can be compared with the correct position

values that are stated between brackets in the

test report.
