Transmission Error Codes (ZF)
TABLE OF FAULT CODES
The fault codes shown in this table are a complete list of codes that are common to more than one version
of the transmission. Some of the versions are 4WG (four speed) and 6WG (six speed).
NOTE:
This fault code list is valid for the ZF Software Versions V 53.x to V58.0

Remarks
11
Logical error at gear range
signal.
TCU detected a wrong signal
combination for gear range.
• Cable from shift lever to TCU
is broken.
• Cable is defective and is
contacted to battery voltage or
vehicle ground.
• Shift lever is defective.
TCU shifts
transmission to
neutral.
OP-Mode:
transmission shut
down.
Check cables from
TCU to shift lever.
Check signal
combinations of shift
lever positions for
gear range.
Failure cannot be
detected in systems
with DW2/DW3 shift
lever.
Fault is taken back if
TCU detects a valid
signal for position.
12 Logical error at direction
select signal.
TCU detected a wrong signal
combination for direction.
• Cable from shift lever to TCU
is broken.
• Cable is defective and is
contacted to battery voltage or
vehicle ground.
• Shift lever is defective.
TCU shifts
transmission to
neutral.
OP-Mode:
transmission shut
down.
Check cables from
TCU to shift lever.
Check signal
combinations of shift
lever positions
F-N-R.
Fault is taken back if
TCU detects a valid
signal for direction at
shift lever.
17 ** S.C. to ground at Solenoid
LIS1 (Function No. 1).
TCU detected a wrong
voltage at output pin, that
looks like a S.C. to vehicle
ground.
• Cable is defective and is
contacted to vehicle ground.
• Solenoid LIS1 (Function No.
1) device has an internal
defect.
• Connector pin is contacted
to vehicle ground.
Customer specific. Check cable from
TCU to Solenoid
LIS1 (Function No.
1) device.
Check connectors
from Solenoid LIS1
(Function No. 1) to
TCU.
Check resistance of
Solenoid LIS1
(Function No. 1)
device.
