Fault code
(Hex)
Int. code
(Dec)
Meaning of the fault code
possible reason for fault detection
Reaction of the TCU
Possible steps to repair
Remarks
Logical error at internal speed input
TCU measures a internal speed over a
threshold and at the next moment the
measured speed is zero
Cable/connector is defective and has bad
contact
Speed sensor has an internal defect
Sensor gap has the wrong size
S.C. to battery voltage or O.C. at output
speed input
TCU measures a voltage higher than 12.5V
at speed input pin
Cable is defective and is contacted to
battery voltage
Cable has no connection to TCU
Speed sensor has an internal defect
Connector pin is contacted to battery
voltage or has no contact
S.C. to ground at output speed input
TCU measures a voltage less than 1.00V at
speed input pin
Cable/connector is defective and is
contacted to vehicle ground
Speed sensor has an internal defect
Logical error at output speed input
TCU measures a turbine speed over a
threshold and at the next moment the
measured speed is zero
Cable/connector is defective and has bad
contact
Speed sensor has an internal defect
Sensor gap has the wrong size
