NOTESPriorities when dealing with a number of faults:
Deal first with faults DF055 Battery voltage too low, DF046 Brake motor/cables
connection, DF042 Force sensor and DF035 Undervoltage if they are present or
stored.
Conditions for applying fault finding procedures to stored faults:
Deal with the fault as if it were present.
Check that the parking brake mechanical tensioning line is correct:
– Parking brake cables correctly fitted.
– Good condition of the parking brake cables (no seizing or deterioration).
– Conformity, condition and correct operation of the brake callipers.
Carry out the necessary repairs.
Check the brake callipers.
Carry out the necessary repairs.
If the fault is still present, contact the Techline without clearing the faults.
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.

1. DEF
NOTESSpecial notes:
The fault does not usually come from the electronic parking
brake computer.
This fault appears as present if the computer supply voltage
is less than 10.3 V, and becomes stored once the voltage
rises back above 10.5 V.
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.
Note:
This fault may appear if starting is very difficult.
Conditions for applying the fault finding procedure to
a stored fault:
Apply this fault finding procedure if the fault reappears as
present after the ignition has been switched on (forced
+ after ignition feed, see Introduction).
2. DEF
NOTESNote:
This fault only affects Vdiag 0D.
Priorities when dealing with a number of faults:
Deal first with faults DF046 Brake motor/cables
connection, DF042 Force sensor, DF035 Undervoltage,
DF041 Slope sensor, DF049 Brake application, DF054
Battery voltage too high and DF055 Battery
undervoltage if they are present or stored.
If none of these faults is present or stored, the parking brake
computer is not normally the cause.
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
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.

Petrol injection).
Note: the value of this parameter
depends on the injection fitted to
