NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– a braking command is issued on a slope.
Priorities when dealing with a number of faults:
Deal with faults: DF046 Brake motor / cables connection, DF050 Mechanical
seizure, DF035 Undervoltage, DF058 Parking brake motor current and DF055
Battery undervoltage first if they are present or stored.
Check that the parking brake mechanical tensioning line is correct:
– that the parking brake cables are fitted correctly (refer to the repair procedure),
– that the parking brake cables are in good condition (not seized or deteriorated),
– that the rear brake callipers are correct, in good condition and operating correctly,
– that the rear brake pads are correct and in good condition.
Carry out the necessary repairs.
Using the diagnostic tool statuses screen, display parameter PR003 Slope value.
If the value displayed is not 0 degrees (± 1) on level ground, carry out slope initialisation again (actuator control
mode menu).
Using the diagnostic tool parameters screen, display the following parameters: PR005 Force setpoint and PR004
Measured force value. These must show the various values recorded in the conformity check.
Clear the fault, switch off the ignition for 5 minutes (vehicle doors and windows closed), switch the ignition back
on and repeat a braking command on a slope.
If the fault reappears, switch off the ignition and disconnect the computer supply fuse (fuse F23 of the engine fuse
box, refer to the wiring diagram) for approximately 1 minute.
Reconnect the fuse, switch the ignition on and establish dialogue with the computer. Apply the brake to check
whether the fault recurs.
If the fault reappears despite the above tests, or if the parameter values are not within conformity check
tolerances while the brake is applied, then contact your Techline.
AFTER REPAIRClear the fault memory.
Follow the instructions to confirm repair.
If 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 possible faults.

2. DEF
NOTESSpecial notes:
The specification 2.DEF mainly comes from a fault with the
electrical power supply, braking application travel or the
internal force sensor.
If this fault appears after the parking brake has been replaced:
– Check the conformity of the parking brake fitting.
– Check that the battery voltage PR001 is greater than 12.5 V.
– Clear the fault and restart the procedure for fitting the parking brake: see Replacement of components.
Check the fault context when the fault appears: if the battery voltage PR001 is less than 9 V when the fault
appears, then:
– Check the supply line and that the resistance is less than 150 m.
– If there is no sign of a fault on the supply line and if PR019 < 3 and PR022 > 25 and PR018 < 15 then clear
the fault.
Check the fault context when the fault appears: If ET028 Brake switch signal is PRESSED, then:
–If PR019 < 3 and PR022 > 25 and PR018 < 15, then clear the fault.
– The fault can be caused when the user depresses the brake pedal hard, when the parking brake is being
applied. If this is the case, clear the fault.
If there is a loud noise when applying, when maximum braking is requested, then the cause may be mechanical.
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 proper functioning of the rear brake callipers.
– Condition and conformity of rear brake pads.
– Conformity of rear brakes bleeding.
Carry out the necessary repairs.
Using the diagnostic tool (PARKING sub-function), display the parameters PR005 Force setpoint and PR004
Measured force value. These must have the various values recorded in the conformity check.
If the fault is still present, 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.

STOREDSYSTEM FAULT AFTER COMPUTER REPLACEMENT
NOTESSpecial notes:
This fault indicates a malfunction due to not following procedures correctly:
replacement or reconfiguration of the electronic parking brake computer was carried
out with a present fault.
Conditions for applying the fault finding procedure to a stored fault:
Deal with the fault as if it were present.
Using the diagnostic tool, run fault finding on the electronic parking brake computer.
Deal with other present or stored faults first.
Carry out any necessary repairs. Clear the fault.
If no fault is displayed on the diagnostic tool, carry out a conformity check to check the conformity of the
parking brake system.
If the conformity check and fault finding with the diagnostic tool have not enabled the fault to be solved
(seeIntroduction) for fault warning light management, to find out which components may be causing the
malfunction.
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.

MAIN SCREEN
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.

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
