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.

Using the diagnostic tool, run fault finding on the multiplex system and particularly on the UCH 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 network test did not find the faulty connection, carry out a conformity check to check that the
statuses coming from the UCH are present and correct (ET001, ET014, ET016, ET017, PR001).
If the statuses and parameters specified are not correct, carry out fault finding on the UCH.
If the fault is still present, disconnect the connectors to ensure that the UCH connectors are in good condition as
well as their clips (terminals), in particular the clips for the multiplex tracks (refer to the wiring diagram for the
UCH 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.

NOTESPriorities when dealing with a number of faults:
This fault must be dealt with first.
Special notes:
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).
Check that the parking brake mechanical tensioning line is correct:
– Check the conformity, condition and correct operation of the brake callipers.
– Check the automatic adjustment of the rear brake callipers.
Contact the Techline without clearing the faults.

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.

1. DEF: Parking brake unlocked by the emergency handle
NOTESPriority when dealing with a number of faults:
Deal first with faults DF003, DF004, DF028, DF029, DF035, DF041, DF042, DF043,
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.
