B/ COMMISSIONING A NEW COMPUTER
1/ COMPUTER CONFIGURATION
– Carry out configuration in accordance with the customer's request (see Configurations and
programming).
2/ VEHICLE IDENTIFICATION NUMBER ENTRY
– run command VP004 Write VIN.
– enter the vehicle identification number using the diagnostic tool keypad,
–confirm.
3/ COMPUTER CALIBRATION AND COMMISSIONING
–In + after ignition feed, run command VP011 Computer calibration and initialisation and carry out
the following 4 steps.
STEP 1 VEHICLE MASS CALIBRATION
Screen 1:
With the dropdown menu, enter the following information:
– vehicle type,
– engine type,
– gearbox type,
– type of driving style,
– equipment level (for Vdiag 04),
– confirm the operation by pressing Next.
Screen 2:
– reread the highlighted information.
– If the highlighted information does not match the vehicle, return to the selection screen by pressing Back,
– if the highlighted information is correct, continue with step 2 by pressing Next.
STAGE 2 INITIALISING A NEW PARKING BRAKE
– Initialise the brake by pressing YES (you should hear a noise as the brake is applied and then released).
– Proceed to step 3 by pressing Next.
STEP 3 SLOPE INITIALISATION
– Calibrate the slope sensor by pressing Confirm. Proceed to step 4 by pressing Next.
STEP 4 INITIALISING ASSISTED BRAKING
– Carry out initialisation by pressing Confirm.
– Return to the selection list screen by pressing Finish. Note:
If the vehicle identification number is not entered and command CF007 Vehicle configuration is not run, step 3
of initialising the computer will not work.
WARNING
To initialise the computer, the vehicle must be on a horizontal surface with the brake cables correctly fitted
(connected to the rear brake callipers) and nobody must be working on the vehicle.

NOTESPriorities when dealing with a number of faults:
Deal with faults DF035 Undervoltage, DF055 Battery undervoltage and DF054
Battery voltage too high first, if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the forced + after ignition is switched on
(seeIntroduction) and an application request using the control lever.
Special notes:
The fault does not usually come from the electronic parking brake computer.
Note:
After a release request, the fault becomes stored.
Replacing the lever with the parking brake applied may cause this fault. If this fault
appears after replacing the lever, release the parking brake and carry out the
procedure again.
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 section.
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 < 3, clear the fault: do not take this fault into account.
Check that the electronic parking brake control lever connector is in good condition and also check its clips
(terminals).
Repair if necessary.
Check that there is a 12 V + before ignition supply on track 6 of the electronic parking brake control lever:
see wiring diagram.
Repair if necessary.
Disconnect the electronic parking brake control lever connector in order to check the insulation, continuity and
absence of interference resistance on the following connection:
Electronic parking brake control lever connector:
1216Electronic parking brake computer connector:
1217
Track 5 Track C4
Repair if necessary.
If the fault is still present, replace the parking brake control lever (the indicator light cannot be separated).
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.

3mm).
This fault appears naturally when the lever is disconnected.
Note:
The fault warning light comes on 10 seconds after the fault appears.
