Fault finding – Conformity check37B
SUB-FUNCTION: AUTOMATIC RELEASE (CONTINUED 3)
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: the value of this parameter 
depends on the injection fitted to

on a level surface:

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
