Display during AEB-Mode - Continued
Symbol Meaning Remarks
ò T transmission oil temperature too high
-> cool down transmission
FT transmission temperature not in defined Transmission stays in neutral, you
range during calibration have to restart the TCU (ignition off/on)
FB operating mode not NORMAL or Transmission stays in neutral, you
transmission temperature sensor defective have to restart the TCU (ignition off/on)
or storing of Calibrated values to
EEPROM-has failed.
FO Outputspeed_not_zero Transmission stays in neutral, you
have to restart the TCU (ignition off/on)
FN Shift lever not in Neutral position Transmission stays in neutral, you
have to restart the TCU (ignition off/on)
FP Parkbrake_not_applied Transmission stays in neutral, you
have to restart the TCU (ignition off/on)
STOP AEB - Starter was used incorrect or is Transmission stays in neutral, you
defective have to restart the TCU (ignition off/on)

Fault MEANING OF CODE TCU reaction Checks Remarks
Code possible reason for fault detection
(hex)
11
LOGICAL ERROR AT GEAR RANGE SIGNAL TCU shifts transmission to •check cables from TCU to Failure cannot be
TCU detected a wrong signal combination for the neutral shift lever detected in systems
gear range OP-Mode: transmission •check signal combinations with DW2/DW3 shift
• cable from shift lever to TCU is broken shutdown of shift lever positions for lever
• cable is defective and is contacted to battery voltage gear range
or vehicle ground
• shift lever is defective
12
LOGICAL ERROR AT DIRECTION SELECT SIGNAL TCU shifts transmission to •check cables from TCU to
TCU detected a wrong signal combination for the neutral shift lever
direction OP-Mode: transmission •check signal combinations
• cable from shift lever to TCU is broken shutdown of shift lever positions
• cable is defective and is contacted to battery voltage F-N-R
or vehicle ground
• shift lever is defective
13
LOGICAL ERROR AT ENGINE DERATING DEVICE after selecting neutral, •check engine derating This fault is reset
TCU detected no reaction of engine while TCU changes to device after power up of
derating device active TCU
15
LOGICAL ERROR AT DIRECTION SELECT SIGNAL 2 TCU shifts transmission •check cables from TCU Fault is taken back if
SHIFT LEVER to neutral if selector to shift lever 2 TCU detects a valid
TCU detected a wrong signal combination for the active •check signal neutral signal for the
direction OP-Mode: transmission combinations of shift lever direction at the shift
• cable from shift lever 2 to TCU is broken shutdown if selector positions F-N-R lever
• cable is defective and is contacted to battery active
voltage or vehicle ground
• shift lever is defective
16
LOGICAL ERROR AT AXLE CONNECTION OP-Mode: normal •check cables from TCU
feedback axle connection measured by TCU to feedback axle
and output signal axle connection don't fit connection switch
• axle can't be connected/disconnected due to •check signals of the
mechanical problem feedback axle connection
• one of the cables from feedback axle connection -
switch to TCU is broken
