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.

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.
Deal with any other faults.

Check that an additional booster battery has not been used when starting, if this is the case, this fault may appear.
Use the diagnostic tool to carry out a multiplex system test.
This check ensures that the various multiplex system connections are correct and finds any faulty segments.
Carry out any necessary repairs.
If the multiplex system test has not made it possible to find the defective connection, disconnect the electronic
parking brake computer connector to check it is in good condition and check the condition of the clips (terminals)
and in particular the clips for tracks A2 and A3.
Replace the clips if necessary.
With the electronic parking brake computer connector disconnected, check the insulation, continuity and the
absence of interference resistance on the connections between tracks A2 and A3 of the electronic parking
brake computer and the following computers:
– anti-lock braking system (see diagram of the various computers),
– injection (see diagram of the different computers),
– automatic transmission (see diagram of the different computers),
– UCH (see diagram of the different computers),
– Protection and Switching Unit (see diagram of the different computers).
Repair if necessary.
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.

NOTESPriorities when dealing with a number of faults:
Deal first with faults DF003 (1.DEF; 2.DEF), DF004, DF028, DF029, DF041, DF042,
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.

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).

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.

NOTESSpecial notes:
This fault is generated after the automatic parking brake is
switched on whilst driving or following an internal reset.
With the anti-lock braking system, this detection is active at
> 0.6 mph (> 1 km/h), otherwise the multiplex signal
emitted by the injection computer must be 1.
Note:
The driver is only informed of this fault after 16 successive
detections.
This fault may be due to battery disconnections or vehicle
supply faults, in which case it is associated with fault 1.DEF
(battery voltage too low) dealt with previously.
If the frequency counter (PR016) > 3 and if the onboard network (battery, wiring) analysis does not bring up any
present or stored fault under battery voltage, contact the Techline.
Check that the battery, battery - starter - alternator connection lead, battery earth - chassis lead and the chassis
earth - engine and transmission assembly lead are in good condition.
Repair if necessary.
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).
Carry out the necessary repairs.

Start the electronic parking brake computer configuration process again: run command VP011 Computer
calibration and initialisation (see Replacement of components).
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).
