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.

NOTESPriorities when dealing with a number of faults:
Deal first with faults DF003 (1.DEF; 2.DEF), DF004, DF028, DF029, DF041, DF042,
DF043, DF050, DF055, DF057, DF058 and DF073.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the ignition is switched on (forced + after ignition
feed, see Introduction) and an application request on a slope.
1. DEF
NOTESSpecial notes:
The 1.DEF code indicates an inconsistency between the
measured force value (PR004) and the parking brake status
(ET030: Electronic parking brake operation when there
is a fault in the fault context).
This fault can appear after disconnecting the battery
(parking brake applied).
Check the context of the fault when the fault appears:
If ET030 is S TAT U S 5 , S TAT U S 6 , S TAT U S 7 , S TAT U S 8 , S TAT U S 9 o r S TAT U S 1 0 and if PR004 is greater than
450 N and if PR012 Vehicle speed is 0 mph (0 km/h) when the fault appears:
– check to see if the battery has been disconnected, if it has, the appearance of this fault is normal, clear the
fault,
– if not, check the computer supply voltage and the battery.
Repair if necessary.
If the fault persists, contact the Techline.
If ET030 is S TAT U S 5 , S TAT U S 6 , S TAT U S 7 and if PR004 is less than 450 N and if PR012 Vehicle speed is
less than 3 mph (5 km/h) when the fault appears:
– Check for traces of heating on the brakes:
– Check that the pads have returned correctly to the rest position.
– Check that the small lever has sufficient return force.
– Check that there is no friction or points of resistance on the cables.
– If there is no indication of any defective operation of these components and if PR019 < 3 and PR022 >
25 and PR018 < 15, then clear the fault.
– If not, contact the Techline.
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.

1. DEF: Problem receiving multiplex frames by the parking brake computer. The
computer is not receiving any multiplex signals or else two computers are not
communicating with the parking brake computer
NOTESPriorities when dealing with a number of faults:
Deal first with faults DF003 (1.DEF; 2.DEF), DF004, DF028, DF029, DF041, DF042,
DF043, DF050, DF055, DF057, DF058 and DF073.
Deal with any faults on the multiplex network first (see 88B, Multiplexing).
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).
Special notes:
This fault indicates either a complete absence of multiplex signal transmission (no
inconsistency) to the parking brake control unit, or no multiplex signal transmission
from two computers (the continuity of the multiplex network lines may be correct, but if
two computers fail to respond, this fault appears).
The fault does not usually come from the electronic parking brake computer.
Note:
Using another battery for a boost when starting may trigger this fault.
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.
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.

DF043, DF050, DF057, DF058 and DF073.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault appears as present again after the ignition
has been switched on
(forced + after ignition feed, see Introduction).
Special notes:
The fault does not usually come from the electronic parking brake computer.
This fault appears as present if the computer supply voltage is greater than 16.5 V,
and becomes stored when the voltage goes back down below 15.7 V.
Note:
Using another battery for a boost when starting may trigger this fault.
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.
Check the charging circuit: the alternator should not supply a voltage of less than + 12 V or greater than + 14.4 V
(engine at idle speed).
Check the alternator and the regulator.
Carry out the necessary repairs.
If the fault is still present, check that no electrical system using the same supply fuse as the electronic parking
brake computer is faulty.
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.

Fault finding – Conformity check
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.
