1. DEF: Inconsistent current value
NOTESConditions for applying the fault finding procedure to a stored fault:
Apply the fault finding procedure even if the fault is stored.
Special notes:
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).
Check to see if battery polarity has been inverted, if this is the case, clear the fault and check that the electronic
parking brake computer is operating correctly (see System operation).
If the fault is still present, contact the Techline without clearing the fault.
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.

OR
STOREDNO PROTECTION AND SWITCHING UNIT MULTIPLEX SIGNAL
1. DEF: Multiplex signals absent or values invalid (fault with the computer generating
the signal or multiplex line connection fault)
NOTESPriority when dealing with a number of faults:
Deal with faults DF055 Battery undervoltage and DF052 Multiplex network first if
they are present or stored.
Deal with any Protection and Switching Unit computer faults first.
The fault does not usually come from the electronic parking brake computer.
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 it has
been cleared, the ignition has been switched back on (forced + after ignition feed:
see Introduction), and the parking brake is released then applied using the control
lever.
Special notes:
This fault only relates to multiplex signals received from the Protection and
Switching Unit computer.
This fault indicates either that there is no signal or that the signals transmitted are
inconsistent.
Note:
If a multiplex line fault such as this is present, the electronic parking brake computer
may lose all or some of its assisted parking functions (application and release).
If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction section.
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.

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.
