automatic mode not available

At standstill:
-

if the vehicle comes to a halt, the clutch will 
open and the gearbox is automatically 
shifted to the neutral position

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

-

driving off from a stationary position

-

No noticeable system limitation

-

Automatic mode available

3210

No CAN message received from the MTCO due 
to:
-

communication problem with the MTCO

-

if the vehicle comes to a halt, the clutch will 
open and the gearbox is automatically 
shifted to the neutral position

-

driving off from a stationary position is not 
possible

-

system is not available

3235

No PTO active signal received by AS Tronic ECU 
from VIC via CAN message due to:

2. SYSTEM INSPECTION WITH DAVIE XD

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.
