AEB Clutch Calibration instructions
Before starting the AEB following instructions must be followed.
Parking Brake must be “on”
Gear selector lever in “ Neutral”
Transmission sump temperature between “ 70 – 90 ° Celsius”
Engine Idle speed between 650 – 1100 rpm – if to low increase engine speed
with gas pedal and keep RPM.
Correct Oil Level – check Dip stick
Vehicle must be on flat surfice level.
Please make shure that safety instructions are followed and no persons next to
the vehicle!
When connecting AEB Starter symbol “ PL” will show up on display.
To start AEB please push red botton at least 3 seconds till “ K1” show up on
display after that release the button “ AEB” will continiue itself.
Finally if clutches could be calibrated “ OK “ will show up on display!
Switch off ignition, for at least 5 seconds.
Any Errors appear during AEB procedure please read the Error code book

2 definition of operating modes
NORMAL:
There's no failure detected in the transmission-system or the failure has no or slight effects on
transmission control. TCU will work without or in special cases with little limitations. (see following
table)
SUBSTITUTE CLUTCH CONTROL:
TCU can't change the gears or the direction under the control of the normal clutch modulation. TCU
uses the substitute strategy for clutch control. All modulations are only time controlled. (Comparable
with EST 25)
LIMP-HOME:
The detected failure in the system has strong limitations to transmission control. TCU can engage only
one gear in each direction. In some cases only one direction will be possible.
TCU will shift the transmission into neutral at the first occurrence of the failure. First, the operator
must shift the gear selector into neutral position.
If output speed is less than a threshold for neutral to gear and the operator shifts the gear selector into
forward or reverse, the TCU will select the limp-home gear .
If output speed is less than a threshold for reversal speed and TCU has changed into the limp-home
gear and the operator selects a shuttle shift, TCU will shift immediately into the limp-home gear of the
selected direction.
If output speed is greater than the threshold, TCU will shift the transmission into neutral. The operator
has to slow down the vehicle and must shift the gear selector into neutral position.
TRANSMISSION-SHUTDOWN:
TCU has detected a severe failure that disables control of the transmission.
TCU will shut off the solenoid valves for the clutches and also the common power supply (VPS1).
Transmission shifts to Neutral. The park brake will operate normally, also the other functions which
use ADM 1 to ADM 8.
The operator has to slow down the vehicle. The transmission will stay in neutral.
TCU-SHUTDOWN:
TCU has detected a severe failure that disables control of system.
TCU will shut off all solenoid valves and also both common power supplies (VPS1, VPS2). The park
brake will engage, also all functions are disabled which use ADM 1 to ADM 8.
The transmission will stay in neutral.
