1. DEF: Battery voltage too high
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.
Deal with any other faults.

2. DEF
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.

brake computer is faulty.
