Fault finding - Function
DEACTIVATING THE SYSTEM
–The parking proximity sensor system can be deactivated in two ways:
–Temporary deactivation: briefly pressing (1 second) the parking distance control switch on the instrument panel
deactivates the system (the red warning light on the switch comes on). The function can be switched on again by
pressing briefly for a second time (the red indicator light on the switch goes out) or by switching the ignition off and
back on.
–Permanent deactivation: The parking distance control system can be deactivated for a longer period by
pressing and holding (for approximately 3 seconds) the parking distance control switch on the instrument panel
(the red warning light on the switch comes on). The function can be switched on again only by pressing and
holding the switch again (the red warning light on the switch goes out).
Fault finding:
In the event of a system fault, the driver will be alerted by a 5-second continuous warning sound with a
different pitch to the detection signal.Note:
The diagnostic tool statuses can be used to determine the function status (ready, detecting, suspended or
deactivated) by using status ET003 Parking distance control function (see Conformity check or the relevant
status interpretation).

Fault finding - Role of components
Description of operation
The system consists of four sensors built into the rear bumper, a computer and a buzzer.
The system assists the driver during parking manoeuvres by warning of any obstacles to the rear of the vehicle.
The sensors and the computer calculate the distance between the vehicle and any obstacles.
The ultrasonic sensors are able to detect different obstacles such as:
–A wall.
–A post.
–A fence.
–A square section tube.
–Runner.
The sensors operate over a distance range from between 26 to 30 cm minimum and 150 cm maximum. If an
obstacle is less than 25 cm away, the signal received (after coming into contact with the obstacle) will be disrupted
by the signal emitted by the sensor, therefore, it is possible that measurements made at this distance will be incorrect
The driver is informed of the distances by a buzzer.
The system only works when the vehicle is in reverse gear. Activation is indicated by a brief 0.5 second activation
sound.
The buzzer is activated when the vehicle is 150 cm from the obstacle. As the distance diminishes, the frequency of
the buzzer increases. When the distance reaches 20 - 30 cm, the buzzer becomes continuous.
–The system can only be activated with + after ignition feed and reverse gear engaged.

REPLACING THE PARKING PROXIMITY SENSOR COMPUTER
BEFORE REPLACING ANY COMPUTER IT IS ESSENTIAL THAT YOU CONTACT TECHLINE.
When replacing the computer, apply the following procedure:
–switch off the ignition,
–replace the computer,
–configure the vehicle identification using command CF005 Vehicle identification (refer to Configurations and
Programming),
–if there is a caravan attachment, check that there is no inconsistent warning sound. If there is, adjust the detection
distance with configuration VP003 “Caravan towbar distance”.
–enter the vehicle identification number with the diagnostic tool using command VP001 “Enter VIN”,
–check that the system is operating correctly and make sure that there are no faults.

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.
Activation of the parking proximity sensor is indicated by a brief 0.5 second activation sound (vehicle in reverse
gear).
After having configured the computer, check that the configuration has taken effect by reading the configuration
LC005 Vehicle identification.
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.
There are five selections:
–ZERO,
–LOW,
–MEDIUM,
–HIGH.
–MAXIMUM
Configuration function CF006 Pitch adjustment is used to adjust the pitch of the buzzer.
There are three choices:
–800 Hz,
–1000 Hz,
–2000 Hz (high pitch).
After configuring the computer, check that these configurations have been registered correctly using configuration
readings LC001 “Buzzer volume” and LC006 “Tone adjustment”. Note:
The system must not be in “Detection” mode during this configuration as the buzzer will remain active until the next
time the + after ignition feed is cut off.
