Using the diagnostic tool, run fault finding on the multiplex network and particularly on the injection computer -
electronic parking brake computer segment.
This check ensures that the various multiplex system connections are correct and finds any faulty segments.
Carry out any necessary repairs.
If the multiplex network test did not find the faulty connection, carry out a conformity check to check that the
statuses and parameters coming from the injection computer are present and correct (ET019, PR015, PR017).
If the status and parameters shown here are not correct, carry out fault finding on the injection.
If the fault is still present, disconnect the injection computer connector to check that it is good condition as well
as its clips (terminals), in particular the clips for the multiplex tracks (refer to the wiring diagram for the injection
system fitted to the vehicle).
Replace the clips 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.

1. DEF: Multiplex signals absent or values invalid (fault with the computer generating
the signal or multiplex line connection fault)
NOTESPriority in the event of a number of faults:
Deal with faults DF055 Battery undervoltage and DF052 Multiplex network first if
they are present or stored.
Deal with any ABS computer faults first.
The fault does not usually come from the electronic parking brake computer.
Note:
If this fault is present, the parking brake loses its assisted application and release
functions.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault reappears as present or stored after a
fault has been cleared and the ignition has been switched off and on again
(forced + after ignition feed: see Introduction).
Special notes:
This fault only relates to multiplex signals received from the ABS computer.
This fault indicates either that there is no transmission, or that the signals received by
the electronic parking brake computer are inconsistent.
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.
If the fault is stored and PR019 < 10, 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.

Using the diagnostic tool, run fault finding on the multiplex system and particularly on the ABS computer-
parking brake control unit segment.
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 did not find the faulty connection, carry out a conformity check to check that the
parameters coming from the ABS computer are present and correct (PR012, PR013, PR014).
If the parameters mentioned are not correct, carry out an ABS computer fault finding procedure (see 38C, Anti-
lock braking system).
If the fault is still present, disconnect the computer connector to check that it is in good condition as well as its
clips (terminals), in particular the clips for the multiplex tracks (refer to the wiring diagram for the ABS computer
fitted to the vehicle).
Replace the clips if necessary.
If the fault persists, contact the Techline.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline), initialise the

Check the vehicle gearbox configuration: check that the configuration is not for a manual gearbox when the
vehicle is fitted with an automatic transmission, or that it is not configured for an automatic transmission when the
vehicle is manual.
Using the diagnostic tool, run fault finding on the multiplex system and particularly on the automatic
transmission computer-parking brake control unit segment.
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 did not find the faulty connection, carry out a conformity check to check that the
status coming from the automatic transmission computer is present and correct (ET018).
If status ET018 is not correct, carry out fault finding on the automatic transmission.
If the fault is still present, disconnect the automatic transmission computer connector to check that it is sound as
well as its clips (terminals), and in particular the clips for the multiplex tracks (refer to the wiring diagram for the
automatic transmission computer fitted on the vehicle).
Replace the clips if necessary.
If the fault persists, contact the Techline.

Special notes:
The slope sensor is internal to the electronic parking brake computer, it cannot be
separated.
Before replacing an electronic parking brake computer, save the data from the old
computer (for vehicles fitted with a manual gearbox).
For this operation, (see Replacement of components).
Contact the Techline without clearing the faults.
