1.4.2.3 The electric steering column lock:
The electric steering column lock is controlled by the UCH. The steering column lock works by inserting and
removing a lock bolt. It replaces the Neimann type lock.
The steering column lock is powered outside + after ignition feed. The steering column lock supply is via the after
ignition relay (located in the Protection and Switching Unit) in its rest position, from where it is distributed to the
column lock by the UCH.
The UCH sends an unlocking request and a code to the steering column lock, via the vehicle's multiplex network.
The multiplex network unlocks the steering column lock if the code is recognised.
A sensor located on the column lock bolt informs the UCH, via the multiplex network and by wire connection, that it
is unlocked.
When unlocking is confirmed, the UCH activates the + after ignition feed via the Protection and Switching Unit. The
column lock is no longer supplied.
The column lock has a "+ after ignition feed present on vehicle" wire signal which inhibits locking while the feed is
active.
1.4.2.4 The injection computer:
The injection computer is coded and unlocks following the encrypted challenge exchange with the UCH.
1.4.2.5 The starting aerials (hands-free vehicles):
There are 3 transmitter aerials located in the passenger compartment. They are controlled by the UCH to interrogate
the card during a starting request or in confirming the presence of the card in the vehicle (e.g. after a door is
opened).
The power used allows the whole passenger compartment to be covered, including the boot. Overspill outside the
passenger compartment is minimal.
1.4.2.6 The card reader:
The card reader is connected to the UCH by a wire connection. It provides the transponder function (like a key
recognition ring). It therefore allows authentication of a Renault card without a battery.
If the card is not detected or recognised during hands-free starting, the card reader flashes to tell the customer to
insert the Renault card.IMPORTANT IMPORTANT
The steering column lock is:
–not removable when the bolt is disengaged,
–fitted with a left-hand thread self-shearing mounting bolt.
