SUB-FUNCTION: AUTOMATIC RELEASE (CONTINUED 6)
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.

parking brakePR005:Force setting In rest position:
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

programming.
Test the assisted brake release.
Check the condition of the clutch system (wear of the different components, possible build-up of grease on
surfaces in friction).
Repair if necessary.
Carry out a multiplex network test (see 88B, Multiplexing) and check for any potential faults on the injection
computer (see 13B, Diesel injection or 17B, Petrol injection), the automatic gearbox computer (see 23A,
Automatic gearbox) and the UCH computer (see 87B, Passenger compartment connection unit).
