Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used following
the + after ignition supply being switched on (without acting on the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
– the electrical lines which correspond to the fault,
– the connectors for these lines (for oxidation, bent pins, etc.),
– the resistance of the faulty component,
– the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool when the data
is inconsistent. Therefore, this stage is used to:
– carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint,
– check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be dealt with by
Customer complaints.
A summary of the overall procedure to follow is provided on the following page in the
form of a flow chart.

MANUAL OPERATION:
– The parking brake is engaged by pulling on the control lever (normal braking immobilises the vehicle).
– Over-application can be obtained by pulling and holding the lever for 5 seconds (maximum application for steep
hills or when the vehicle has reached its maximum permissible all-up weight).
– When the parking brake is applied, the computer super-applies if the force applied to the rear brake callipers is
insufficient (pads cooling) or if the computer detects slight vehicle movement. This detection is limited to
24 hours.
– The parking brake is released when the control lever is applied fully and the release switch is pressed.
ASSISTED OPERATION:
The electronic parking brake enables assisted application and release of the brake:
●Applying the brake: When the engine is switched off, the parking brake is applied when the driver presses the
start button
●Releasing: The brake releases when the drive wheels reach the torque required to move the vehicle
(Note:with automatic transmission, the driver's door must be closed).
Restrictions on assisted brake release in automatic transmissions:
Assisted release is not allowed in the following cases:
– Opening the driver's door followed by engaging a gear (gear lever in position D).
– Engaging a gear (gear lever in position D) followed by opening the driver's door. Note:
When the parking brake is applied, the red light on the instrument panel (brake pads) and indicator light on the
lever are lit.
Below 6 mph (10 km/h) pulling the lever applies the rear brakes. Above 6 mph (10 km/h) pulling the lever
provides dynamic emergency braking without locking the rear wheels (statutory deceleration of 1.5 m/s
2).
The electronic parking brake can only be released when the steering column is unlocked (forced + after ignition
feed, see Introduction).
Note: In this case, the instrument panel displays the message Lever in P or N and the buzzer on the instrument
panel sounds.
Note: In this case, release is authorised for 5 s after the driver's door has been opened (e.g. for a manoeuvre).
After 5 seconds release is prevented.
Note:
Assisted braking and release only occurs if the computer has been configured.
For details on how these configurations function, see Configuration and programming.

WARNING LIGHT MANAGEMENT
Indications of a level 1 fault:
–Check Parking Brake message on the instrument panel display.
–orange warning light (P in a triangle) on the instrument panel comes on.
–SERVICE warning light comes on.
Indications of a level 2 fault:
–Parking brake defective message on the instrument panel display.
–1-second audible warning (from the instrument panel),
–orange warning light (P in a triangle) on the instrument panel comes on.
–SERVICE warning light comes on,
–Red indicator light (brake pad light) on the instrument panel comes on.
– parking brake control lever indicator light flashes.
Warning occurs:
– when the door is opened and a gear is engaged on an automatic transmission,
– when the vehicle is moving, despite the parking brake being applied,
– when the door is opened, with the engine running and the parking brake released,
– when the door is opened, with the engine stopped and the parking brake released, Note:
When the lever warning light stops flashing, the instrument panel message disappears. If the system has a level 2
fault, whenever the lever is used, the indicator light on the lever starts flashing again and the fault message
reappears.

2. DEF
NOTESSpecial notes:
– This fault indicates that the electronic parking brake
computer detected front wheel movement although the
parking brake was applied with maximum force.
When this fault appears on its own it is an operating warning
that indicates that the vehicle's conditions of use are on the
limit (the braking system and parking brake are not normally
the cause).
This fault is an operational warning. Check the context in
which it appears.
It may appear during:
– an application request, whilst the vehicle is still being
driven,
– forced assisted release when starting, when the
starting conditions have not been met,
– parked on a steep slope with slippery surface,
– incorrect use of a roller test bench which drives the
front wheels (MOT test).
If the fault is stored, refer to the statuses and
parameters when it appears. Explanation of counters:
seeIntroduction section.
If the fault is stored and PR018 = 0 and PR022 > 25 clear
the fault: do not take this fault into account.
Using the diagnostic tool, display the wheel speed parameters on the parameters screen.
When stationary, these parameters must show 0 mph. If this is not the case, carry out fault finding on the anti-
lock braking system (see 38C, Anti-lock braking system).
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.
Carry out the necessary repairs.
Check that the vehicle is not overloaded.
Check that the vehicle's tyres are not bald.
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.

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.
