Fault finding – Conformity check37B
SUB-FUNCTION: AUTOMATIC RELEASE (CONTINUED 2)
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, check 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:
This status only works
with the driver's door.If the status is not operating as
shown, check that the UCH is
correctly sending the signal
(absence of faults DF039 No UCH
multiplex signal and DF052
Multiplex network). If the status
operates with the passenger door
but not the driver's door,
reinitialise the computer by
running command VP011
Computer calibration and
initialisation (see Replacement
of components) to configure the
correct type of steering (right or
left-hand drive).
If the fault is still present, run fault
finding on the UCH (see 87B,
Passenger compartment
connection unit).

If the fault is still present, run fault

(see 13B, Diesel injection or 17B,
Petrol injection).
Note: the value of this parameter
depends on the injection fitted to
the vehicle. The values noted in
this check are therefore only
average values (refer to the
injection conformity check). Pedal depressed fully
(depressed past
resistance point):
110 < X < 120%
Invalid value: 118%
(this value means that
the signal is not being
received, e.g.: ignition

X = 0 N
When applying the brake
on a level surface:
400 < X < 550 N
When fully applied (lever
fully pulled for 2 seconds)
on a level surface:
1100 < X < 1150 N
Note: depressing the
brake pedal once when
the parking brake is
applied changes the
measured force value
(change in the tension of
the brake cables) and the
parking brake may be
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 DF050
Mechanical jamming). If one
of these three faults is
displayed by the diagnostic
tool, use the relevant
interpretation. PR004:Measured force

NOTESNone
This status means there is a + 12 V computer after ignition.
When the ignition is switched off, the status displays: ABSENT.
When the ignition is switched on, the status displays: PRESENT.
If the status does not operate as specified: disconnect the electronic parking brake computer connector to check
the insulation, continuity and the absence of interference resistance on the following connections:
Automatic parking brake computer connector
track H4
(except Laguna II, Vel Satis and Espace IV) track G4 + 12 V
track H2
(except Laguna II, Vel Satis and Espace IV) track G2 earth
Repair if necessary (see the vehicle wiring diagram).
If the connections are correct, the power is correctly supplied to the electronic parking brake computer, but the
fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.
