1. DEF: Multiplex signals absent or values invalid (fault with the computer generating
the signal or multiplex line connection fault)
NOTESPriority in the event of a number of faults:
Deal with faults DF055 Battery undervoltage and DF052 Multiplex network first if
they are present or stored.
Deal with any injection computer faults first.
The fault does not usually come from the electronic parking brake computer.
Note:
If there is a multiplex line fault like this one, the parking brake loses its assisted
application and release functions.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault reappears as present or stored after a
fault has been cleared, and the ignition has been switched off and on again (forced
+ after ignition feed: see Introduction).
Special notes:
This fault only relates to multiplex signals received from the injection computer.
This fault indicates either that there is no transmission, or that the signals received by
the parking brake are inconsistent.
Only for Vdiag 08, 0C and 0D:
If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction section.
If the fault is stored and PR018 = 0 and PR022 > 25, clear the fault:
do not take this fault into account.
If the fault is stored and PR019 < 10, clear the fault:
do not take this fault into account.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline), initialise the
electronic parking brake computer (see Replacement of components).
Issue several braking and release commands to confirm the repair.
Deal with any other faults.

Using the diagnostic tool, run fault finding on the multiplex system and particularly on the ABS computer-
parking brake control unit segment.
This check ensures that the various multiplex system connections are correct and finds any faulty segments.
Carry out any necessary repairs.
If the multiplex system test did not find the faulty connection, carry out a conformity check to check that the
parameters coming from the ABS computer are present and correct (PR012, PR013, PR014).
If the parameters mentioned are not correct, carry out an ABS computer fault finding procedure (see 38C, Anti-
lock braking system).
If the fault is still present, disconnect the computer connector to check that it is in good condition as well as its
clips (terminals), in particular the clips for the multiplex tracks (refer to the wiring diagram for the ABS computer
fitted to the vehicle).
Replace the clips if necessary.
If the fault persists, contact the Techline.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline), initialise the
electronic parking brake computer (see Replacement of components).
Issue several braking and release commands to confirm the repair.
Deal with any other faults.

interference resistance on the following connections:
Parking brake lever connector: 1216Electronic parking brake computer: 1217

track C2
Repair if necessary.
With the parking brake control lever connector disconnected, switch on the ignition and check for a 5 V supply
(4 V < X < 5 V) on track 7 of the lever connector. If the power supply is not present and the parking brake
computer is correctly supplied (no other faults detected by the diagnostic tool), then contact the Te c h l i n e.

brake control lever.
Replace the lever (see MR405 (Espace IV), MR395 (Laguna II) or MR370 (Scénic), Mechanical, 37B,
Electronic parking brake, Lever: Removal - Refitting or MR353 (Vel Satis), Mechanical, 37B, Automatic
