1.1 GENERAL

The Allison transmission is electronically

controlled and has a diagnostics system that can

record any faults in the memory of the ECU

(Electronic Control Unit). The faults can be read

at a later date. The system is operated and the

faults are read via the selector keypad.

This selector has a display and is located

immediately next to the driver's seat. The selector

replaces the gear lever with manually operated

gearboxes.

1.2 SYSTEM DESCRIPTION

"Gearbox" warning symbol
When the vehicle ignition is switched on, the

"gearbox" warning symbol will not appear on the

DIP display.

If the gearbox symbol in the main display lights

up, there is a fault in the gearbox (changing gear)

or the temperature of the gearbox oil is too high.

The "gearbox" warning symbol in the DIP will then

be displayed in yellow. The selector keypad LED

will also flash three times. The accompanying

fault code can be read on the selector display.

The ECU will block the functions of the selector

and the gearbox will select a "safe gear" for the

gearbox. It is important to drive the vehicle to a

safe place as soon as possible and switch the

ignition off. It will no longer be possible to shift the

gearbox to neutral. The ECU will prevent this.

After approximately 30 seconds start the engine

again and shift the gearbox. If the fault is one

whereby the gearbox must in no circumstances

be shifted, the ECU will no longer shift the

gearbox.

The warning symbol in the display of the DIP will

then appear in red. The "STOP" warning indicator

will also light up.

Driving is therefore no longer possible!

If the fault is one whereby the gearbox may still be

shifted, the warning in the main display will

disappear. The ECU will have recorded the fault

as an inactive fault.

It is now possible to drive the vehicle again,

though the fault will still need to be remedied. In

this situation, however, it is no longer possible to

shift gears.
