Fault finding - Configurations and programming
CONFIGURATION AFTER REPLACING THE COMPUTER
After replacing the computer, configure the parking distance control computer with the vehicle type using
configuration CF005 Vehicle identification (repair mode menu, diagnostic tool configuration function). The
configuration adapts the sensors' detection field to the type of body.
Depending on a vehicle's gearbox type (automatic or manual), the parking distance control can be delayed from
working. Activation of the parking distance control is indicated by a brief 0.5 second activation sound (vehicle in
reverse gear). On vehicles with an automatic transmission, the 3-second delay prevents the activation noise from
sounding every time the driver shifts from Park to Drive.
After having configured the computer, check that the configuration has taken effect by reading the configuration
LC005 Vehicle identification.
Special note (Vdiag 08 only):
If a vehicle is fitted with a caravan towbar and if there is a continuous beeping noise, take the towbar out of the
detection field for the rear sensors, run the command for parameter VP003 Caravan towbar distance, then increase
the detection area centimetre by centimetre. To avoid impairing the detection, the parameter PR026 Caravan towbar
distance must not exceed 40 cm.
SETTING OPTIONS
The volume and the tone of the buzzer can be changed if the customer desires.
Configuration CF001 Buzzer volume is used to adjust the volume of the buzzer.
Configuration function CF006 Pitch adjustment is used to adjust the pitch of the buzzer.
After configuring the computer, check that the configurations have been registered correctly using configuration
readings LC001 Buzzer volume and LC006 Tone adjustment.

1.DEF : Internal electronic fault
2.DEF : Internal electronic fault
3.DEF : Internal electronic fault
4.DEF : Internal electronic fault
NOTESConditions for applying the fault finding procedure to stored faults:
The fault reappears present or stored after its has been cleared, the ignition is switched
on and off again and reverse gear is selected.
Special notes:
If the fault is present and is represented by 1.DEF or 2.DEF, the system operates in
defect mode (substitute values are used).
If the fault is present and characterised 3.DEF and the buzzer fails to sound when
shifting into reverse, contact your Techline.
1.DEF
2.DEF
NOTES None
After following the instructions, if the fault recurs, switch off the ignition and disconnect the parking distance control
computer supply fuse (see vehicle diagram).
Reconnect the fuse, switch the ignition back on, and perform a fault reading.
If the fault recurs, check the connections and condition of the parking distance control computer 16-track
connector (no damage to the connections).
Repair if necessary.
With the ignition switched off, disconnect the parking distance control computer 16-track connector to check
the conformity of the supplies and to check the insulation, continuity and the absence of interference
resistance on the following connections:
16-track parking distance control computer connector with 1 connector:
Track 1+ after ignition feed
Track 3earth
AFTER REPAIRClear the stored faults.
Follow the instructions to confirm repair.
Deal with any faults.

NOTESSpecial notes:
Before searching for a fault with these parameters, make sure no fault is present or
stored. If there is a fault, apply the interpretation for the fault detected by the
diagnostic tool.
Note:
The ultrasonic sensors are very fragile. Therefore, when removing the rear bumper, be
careful not to scratch them.
An obstacle which is further than 150 cm away cannot be detected, the parameter
value is 255 in this case. For an obstacle which is between 20 and 150 cm away, the
parameter value is the distance to the obstacle.
For an obstacle which is closer than 20 cm away, the value of the parameters is 0.
Using the diagnostic tool configuration reading screen (repair mode menu), check that the parking distance
control system is configured correctly for the vehicle type to which it is fitted (LC005 Vehicle identification).
If necessary, reconfigure the computer using command CF005 Vehicle identification.
Check, when the vehicle is close to an obstacle (between 20 and 150 cm), that the distance evaluated corresponds
to the distance displayed by the diagnostic tool (PR001 to PR004).
If the distance is incorrect or if the distance parameters remain at 255, make sure nothing is interfering with the
reading (sticker, mud, snow etc. on the rear bumper).
If the distances displayed by the sensors seem incorrect or if 255 is displayed continuously, check the condition of
the sensor(s). There must be no scratches on the detection component (outer metal section) of the sensors.
Replace the defective sensor.
If the fault is still present, apply the fault finding procedure to the sensor whose distance parameter is incorrect
(even if the diagnostic tool does not report a fault).
AFTER REPAIRRepeat the conformity check from the start.
