S.C. TO BATTERY VOLTAGE OR
O
.C. AT ENGINE SPEED INPUT
TCU measures a voltage
higher than 7.00 V 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
OP-Mode: substitute
clutch control
check the cable from
TCU to the sensor
check the connectors
check the speed
sensor

S.C. TO GROUND AT ENGINE
SPEED INPUT
TCU measures a voltage
less than 0.45V at speed
input pin
cable / connector is
defective and is contacted
to vehicle ground
speed sensor has an
internal defect
OP-Mode: substitute
clutch control
check the cable from

LOGICAL ERROR AT ENGINE
SPEED INPUT
TCU measures a engine
speed over a threshold and
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
OP-Mode: substitute
clutch control
check the cable from
TCU to the sensor
check the connectors
check the speed
sensor
check the sensor gap
This fault is reset after
power up of TCU
