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)

TABLE OF FAULT CODES
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
23 S.C. TO BATTERY VOLTAGE AT LOAD SENSOR INPUT retarder function is affected •check cable from TCU to Availability of retarder
the measured voltage is too high: TCU uses default load sensor depends on default load
•
cable is defective and is contacted to battery voltage OP-Mode: normal •check connectors
•
load sensor has an internal defect •check load sensor sensor
•
connector pin is contacted to battery voltage •check assembly tolerances
of load sensor
24 S.C. TO GROUND OR O.C. AT LOAD SENSOR INPUT retarder function is affected •check cable from TCU to Availability of retarder
the measured voltage is too low: TCU uses default load sensor depends on default load
•
cable is defective and is contacted to vehicle ground OP-Mode: normal •check connectors
•
cable has no connection to TCU •check load sensor sensor
•
load sensor has an internal defect •check assembly tolerances
•
connector pin is contacted to vehicle ground or is of load sensor
broken
25 S.C. TO BATTERY VOLTAGE OR O.C. AT TRANSMISSION SUMP no reaction, •check cable from TCU to
TEMPERATURE SENSOR INPUT TCU uses default temp. sensor
the measured voltage is too high: OP-Mode: normal •check connectors
•
cable is defective and is contacted to battery voltage •check temperature sensor
•
cable has no connection to TCU
•
temperature sensor has an internal defect
•
connector pin is contacted to battery voltage or is
broken
