Transmission Error Codes (ZF)
96 ** O.C. at relay starter interlock.
TCU detected a wrong
voltage at output pin, that
looks like a O.C. for this output
pin.
• Cable is defective and has
no connection to TCU.
• Starter interlock relay has an
internal defect.
• Connector has no
connection to TCU.
No reaction.
OP-Mode: normal.
Check cable from
TCU to starter
interlock relay.
Check connectors
from starter interlock
relay to TCU.
Check resistance
1)
of starter interlock
relay.
1)
See
“Measurement of
Resistance at
Actuator/sensors
and Cable” on page
35.
98 * O.C. at LIS2 solenoid valve.
The measured resistance
value of the valve is out of
limit.
• Cable/connector resistance
and has no contact to TCU.
• Valve has an internal defect.
No reaction.
OP-Mode: normal.
Check the cable from
TCU to the valve.
Check the
connectors from
valve to TCU.
Check the valve
resistance.
If fault code 95 and
98 are both being
displayed for about
one second each,
see combined fault
code.
B1 Slippage at clutch K1.
TCU calculates a differential
speed at closed clutch K1. If
this calculated value is out of
range, TCU interprets this as
slipping clutch.
• Low pressure at clutch K1.
• Low main pressure.
• Wrong signal at internal
speed sensor.
• Wrong signal at output
speed sensor.
• Sensor gap is incorrect.
• Clutch is defective.
TCU shifts to neutral.
OP-Mode: limp
home.
If failure at another
clutch is pending.
TCU shifts to neutral.
OP-Mode: TCU shut
down.
Check pressure at
clutch K1.
Check main
pressure in system.
Check sensor gap at
internal speed
sensor.
Check sensor gap at
output speed sensor.
Check signal at
internal speed
sensor.
Check signal at
output speed sensor.
Replace clutch.
