BRAKE PEDAL
Note:
Status ET018 "Gear engaged" is applicable to the following sub-functions:
–"Driver parameters".
STATUS
DEFINITIONDEPRESSED: shows that the brake pedal is depressed.
RELEASED: shows that the brake pedal is released.
STATUS1: shows that the brake switch signal is invalid.
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.
"DEPRESSED"
(Brake pedal
depressed)
When the driver depresses the brake pedal status ET018 Brake pedal becomes
DEPRESSED.
If the driver depresses the brake pedal hard and status ET018 Brake pedal remains
RELEASED with the lights operating:
Check the insulation, continuity and the absence of interference resistance on the
following connection:
–Connection code 5A
between the brake light switch connector, component code 160 and the transmission
computer, component code 119.
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.
–Remove the brake light switch and carry out the following checks:

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.
