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 automatic transmission computer faults first.
The fault does not usually come from the electronic parking brake computer.
Note:
If this fault is present, 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 automatic transmission
computer.
This fault indicates either that there is no signal or that the signals transmitted 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.
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 < 15 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.

Special notes:
The force sensor is internal to the electronic parking brake

Before replacing an electronic parking brake computer,
save the data from the old computer (for vehicles fitted
with a manual gearbox).
For this operation, (see Replacement of components).

undervoltage and DF054 Battery voltage too high, if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the ignition is switched on (forced + after ignition
feed, see Introduction) and an application request using the control lever.
The fault does not usually come from the electronic parking brake computer.
Special notes:
The braking switch is in fact the first contact of the lever (the lever travels about
3mm).
This fault appears naturally when the lever is disconnected.
Note:
The fault warning light comes on 10 seconds after the fault appears.

Conditions for applying the fault finding procedure to a stored fault:
This fault must be dealt with first.
Special notes:
The fault does not usually come from the electronic parking brake computer.
The redundant brake switch is the second contact of the lever (maximum lever travel).

If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction.
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 < 3, clear the fault: do not take this fault into account.
Using the diagnostic tool (PARKING sub-function), check the operation of the parking brake control lever. With
the ignition switched on, statuses ET008, ET009 and ET010 should operate as follows:
ET008 "Engagement
switch position"ET009 "Redundant
braking switch position"ET010 "Release switch

If the statuses do not operate as explained above, check the connection and condition of the parking brake
control lever connector.
Repair if necessary.
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.

DF050, DF054, DF055, DF057, DF058 and DF073 if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault recurs after the fault is cleared, with the
ignition switched off and on again (forced + after ignition feed, see Introduction),
and the parking brake released then applied using the control lever.
Special notes:
The fault does not usually come from the electronic parking brake computer.
This fault indicates that the electronic parking brake system has been unlocked by the
manual control (if this is the case, check that the handle protector has not been
damaged).
Check that the emergency unlocking handle has not been manually pulled by the
user, which would provoke this fault.
The cables are reset by the parking brake release manual command or automatically
(if the fault is present) when the vehicle is driven at more than 1.2 mph (2 km/h)
(the fault is then stored).
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.
If the fault is stored and PR018 = 0 and PR022 > 25 clear the fault: do not take this
fault into account.
If there has been no manual use of the emergency unlocking handle and if PR019 > 5,
contact the Techline.
Check that the fault was not provoked by manual usage of the emergency unlocking handle. In this case, it is
normal for the fault to arise; clear the fault.
Carry out a releasing command, then a braking command with the control lever to reset the cables of the parking
brake.
Check the conformity of the parking brake mechanical tensioning line: correctly attached, no breakage.
Check the conformity of the emergency unlocking cable.
Carry out the necessary repairs.
Check that the braking force and maximum braking are operating correctly.
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.
