NOTESPriorities when dealing with a number of faults:
Deal first with faults DF003 (1.DEF; 2.DEF), DF004, DF028, DF029, DF041, DF042,
DF043, DF050, DF057, DF058 and DF073.
Special notes:
This fault only appears during configuration of the parking brake.
The fault does not usually come from the electronic parking brake computer.
Conditions for applying the fault finding procedure to a stored fault:
Deal with the fault as if it were present.
Check that the battery voltage PR001 is above 12.5 V.
Check that the mechanical tensioning line is correctly fitted: cables, connections, callipers.
If the parking brake cables are damaged (particularly at the calliper collars), replace both cables (see MR405
(Espace IV) or MR395 (Laguna II) or MR370 (Scénic), Mechanical, 37A, Mechanical component controls,
Parking brake cables: Removal - Refitting or MR353 (Vel Satis), Mechanical, 37B, Automatic parking
brake, Brake cables).
Start the electronic parking brake computer configuration process again: run command VP011 Computer
calibration and initialisation (see Replacement of components).
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.

Fault finding – Conformity check37B
MAIN SCREEN (CONTINUED 1)
NOTESOnly carry out this conformity check after carrying out a complete check using the
diagnostic tool.
Application conditions: ignition on (forced + after ignition, see Introduction)
Note:
The interpretation of these statuses and parameters is only valid with the
ignition switched on, the statuses and parameters displayed in blue on the
diagnostic tool is information supplied by other computers, which are transmitted via
the multiplex network. If these variables display inconsistent values, make sure that
the multiplex system test has not shown up any faulty connections. Repair the faulty
multiplex connections before looking for a possible problem with the signals.
Each sub-function in this test is associated with a Fault finding chart.
Special notes
The diagnostic tool may display the message Computer busy when displaying
statuses and parameters. This message is displayed when the parking brake is
applying or releasing the brake, because the computer gives priority to controlling the
motor before transmitting variables. If this message is displayed, exit the current
screen and then return to it.

Note: depressing the
brake pedal once when

over-applied.
Interpretation of these
parameters is only valid
without any pressure on
the brake pedal.The difference between the
reference and measured
values must not be more than
-50 N or + 100 N. If the
measured value does not
reach or exceeds the reference
value (mechanical or electrical
fault with the control), the
electronic parking brake
computer will detect a fault
(DF025 Vehicle movement
with maximum application,
DF049 Brake application or

tool, use the relevant
interpretation. PR004:Measured force
