1. DEF: Inconsistent braking value
2. DEF: Normal brake application value not reached
3. DEF: Normal brake release value not reached
4. DEF: Insufficient braking force
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.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the ignition is switched on (forced + after ignition
feed, see Introduction) and an application request on a slope.
1. DEF
NOTESSpecial notes:
The 1.DEF code indicates an inconsistency between the
measured force value (PR004) and the parking brake status
(ET030: Electronic parking brake operation when there
is a fault in the fault context).
This fault can appear after disconnecting the battery
(parking brake applied).
Check the context of the fault when the fault appears:
If ET030 is S TAT U S 5 , S TAT U S 6 , S TAT U S 7 , S TAT U S 8 , S TAT U S 9 o r S TAT U S 1 0 and if PR004 is greater than
450 N and if PR012 Vehicle speed is 0 mph (0 km/h) when the fault appears:
– check to see if the battery has been disconnected, if it has, the appearance of this fault is normal, clear the
fault,
– if not, check the computer supply voltage and the battery.
Repair if necessary.
If the fault persists, contact the Techline.
If ET030 is S TAT U S 5 , S TAT U S 6 , S TAT U S 7 and if PR004 is less than 450 N and if PR012 Vehicle speed is
less than 3 mph (5 km/h) when the fault appears:
– Check for traces of heating on the brakes:
– Check that the pads have returned correctly to the rest position.
– Check that the small lever has sufficient return force.
– Check that there is no friction or points of resistance on the cables.
– If there is no indication of any defective operation of these components and if PR019 < 3 and PR022 >
25 and PR018 < 15, then clear the fault.
– If not, contact the Techline.
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.
