NOTESSpecial notes:
Apply the checks only if statuses ACTIVE and INACTIVE are inconsistent
with the pedal position.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/

Check the insulation between connections MAM (for Logan, Sandero, Duster) or
M (for Thalia 2/Symbol 2, Clio II F 6) and 86D of component 675 with the switch in
the rest position.
– Repeat this operation with the switch pressed, and check the continuity and the
absence of interference resistance between the two connections.
If these 2 checks are not correct, replace the clutch pedal position sensor,

STATUS DEFINITIONACTIVE: This status indicates that the relay is supplied.
INACTIVE: This status indicates that the relay is not supplied.
Conformity check: Engine stopped, ignition on or engine running.
INACTIVEStatuses ET734, ET735 and ET736 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
ACTIVEStatuses ET734, ET735 and ET736 are ACTIVE when the engine is started, the
engine coolant temperature is low (< 15°C) and the air temperature is low (<5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
To control the operation of the relays, run the following commands:
AC250 Heating resistor no.1 relay.
AC251 Heating resistor no.2 relay.
AC252 Heating resistor no.3 relay.

PROTECTED STATUS 3:
There are several possible causes, in the following order:
– check that the UCH computer has not detected a fault,
– Run fault finding on the UCH computer.
– check that the injection computer has not already been programmed with the immobiliser code for another
vehicle using the status.
– Check that the injection computer corresponds correctly to the vehicle on which fault finding is being run.
– if none of the 2 previous points is the cause, check that the injection computer is not in anti-scanning mode after
undergoing several failed authentication attempts,
– It only leaves this mode when the following sequence of operations is carried out:
1- switch off the ignition,
2- switch on the ignition again and wait for at least 20 seconds under + after ignition feed,
3- switch off the ignition and ensure that the end of the self-feed phase of the injection computer is observed (the
length of time varies depending on the engine coolant temperature and can be 10 minutes maximum),
4- switch on the ignition again and start the vehicle,
5- if the vehicle does not start, repeat this procedure 3 times,
6- if the vehicle still does not start, contact the Techline.
