DOWNSHIFT REQUEST
Note:
Status ET086 "Downshift request" is applicable for the following sub-functions:
–"Gear changes".
–"Driver parameters".
STATUS
DEFINITIONACTIVE: shows that the downshift mode is active.
INACTIVE: shows that the downshift mode is inactive or is faulty during a downshift
request.
NOTESSpecial notes:
This status arises with the engine running, the vehicle in motion and during a fast
downshift with the accelerator pedal fully depressed.
Conformity check with the engine stopped, ignition on or engine running.
INACTIVE
ACTIVE
Status ET086 "Downshift request" must be "INACTIVE", with the engine stopped and
ignition on.
If status ET086 "Downshift request" is "ACTIVE", perform the following checks:
Run a multiplex network test (see 88B, Multiplex).
Carry out a test on the engine management computer ((see 13B, Diesel injection,
Conformity check) (EDC16 CP33 M9R 721)).
If the fault is still present, contact Techline.
Status ET086 "Downshift request" must be "ACTIVE" when the accelerator pedal is
fully depressed. If status ET086 "Downshift request" remains "INACTIVE", perform the
following checks:
Run a multiplex network test (see 88B, Multiplex).
Carry out a test on the engine management computer ((see 13B, Diesel injection,
Conformity check) (EDC16 CP33 M9R 721)).
If the fault is still present, contact Techline.
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.
