TORQUE CONVERTER
Note:
Status ET071 "Torque converter" is applicable to the following sub-function:
–"Gear changes".
STATUS
DEFINITIONOPEN: shows that the torque converter is not locked up.
SLIPPING: shows that the torque converter is in a phase between open → lock-up or
in a phase between lock-up → open.
CLOSED: shows that the torque converter is locked up.
INVALID: shows that the torque converter is faulty.
NOTESSpecial notes:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Note:
In manual mode, the torque converter is always locked up.
Conformity check with engine stopped and ignition on.
OPEN
Engine stopped, in position "N", status ET071 "Torque converter" must be "OPEN".
In the event of a fault, consult the interpretation of fault DF097 "Torque converter
lock-up".
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

MANUAL MODE
Note:
Status ET097 "Manual mode" is applicable for the following sub-functions:
–"Gear changes".
–"Driver parameters".
STATUS
DEFINITIONINACTIVE: indicates that the manual mode is inactive whenever the gear lever is not
in "M" position, or when manual mode is faulty.
M +: shows that the gear lever is in position M +.
M -: shows that the gear lever is in position M -.
ACTIVE: indicates that manual mode is active when the gear lever is in position "M".
NOTESSpecial notes:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Conformity check with engine stopped, ignition on or engine running.
INACTIVE
Check that, with gear lever in a position other than "M", status ET097 "Manual mode"
is "INACTIVE".
If a fault occurs, check that status ET012 "Gear lever position" corresponds to the lever
position.
Look for any damage to the wiring and check the condition and connection of the
connectors for components 119 and 129.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
Check the continuity and insulation of the following connections:
●connection code 5H (sequential lever M+ signal),
●connection code 5FM (sequential lever M- signal),
between components 119 and 129.
Check for + 12 V after ignition feed on connection AP43 of component 129.
Check for earth on connection N+ of component 129.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Check that, with gear lever in position "M +", status ET097 "Manual mode" is "M +".
In the event of a fault, check that lever position "M" in Manual mode matches status
ET012 "Gear lever position".
Check, by moving the gear lever to "M+" and "M-", that the two positions correspond to
the two statuses "M+" and "M-" of status ET097 "Manual mode".
Look for any damage to the wiring and check the condition and connection of the
connectors for components 119 and 129.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A,

If the connection or connections are faulty and there is a repair procedure
(see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
Check that, with gear lever in position "M -", status ET097 "Manual mode" is "M -".
In the event of a fault, check that status ET012 "Gear lever position" corresponds to
the lever position in Manual mode "M".
Check, by moving the gear lever to "M+" and "M-", that the two positions correspond to
the two statuses "M+" and "M-" of status ET097 "Manual mode".
Look for any damage to the wiring and check the condition and connection of the
connectors for components 119 and 129.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
Check the continuity and insulation of the following connections:
●connection code 5FM (sequential lever "M-" control),
between components 119 and 129.
Check for + 12 V after ignition feed on connection AP43 of component 129.
Check for earth on connection N+ of component 129.
If the connection or connections are faulty and there is a repair procedure
(see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
