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:

"STATUS 1"
If the checks are not in order, replace the brake light switch.
If the driver depresses the brake pedal and status ET018 Brake pedal is DEPRESSED
but the brake lights do not operate:
–Check the condition and fitting of the brake light switch, the brake light fuse and the
brake light bulbs.
–Check for + after ignition feed on connections SP17 and BPT on the brake light
switch.
When the driver releases the brake pedal status ET018 Brake pedal becomes
RELEASED.
If this does not happen, check that the brake light switch is in good condition and
operating correctly by carrying out the checks associated with status DEPRESSED.
Check the status and operation of the brake light switch by performing the checks
associated with the "DEPRESSED" status.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

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.

This status involves slip action when changing gear during a road test.
IMPORTANT
It is essential to have 2 people to perform these checks during a road test.
In the event of a fault, consult the interpretation of fault DF097 "Torque converter
lock-up".
Check (engine running at idle speed and brake pedal depressed), lever in position "R",
ET013 "Gear engaged" = "R" or lever in position "M", ET013 "Gear engaged" = "1",
"2", "3".
In the event of a fault, consult the interpretation of fault DF097 "Torque converter

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.
