CC.0: Short circuit to earth
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:
The sensors are directly supplied with + 12 V by the computer.
With the parking proximity sensor computer 16-track connector connected and with the ignition on, measure the
sensor power supply coming from the computer. The voltage should be equal to the battery voltage (± 0.5 V)
when measuring between connections 151U (+ 12 V) and 151V (earth).
If there is no + 12 V supply between connections 151U and 151V, remove the rear bumper to access the sensors.
Switch off the ignition, and disconnect the parking proximity sensor computer to check the insulation and
continuity and the absence of interference resistance on the following connections:
●Connection code 151U,
●Connection code 151V.
Between components 1222 and 1218, 1219, 1220, 1221.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring or replace it.
If the sensor power supply is correct (no short circuit), reconnect the computer connector and four sensor
connectors.
Turn on the ignition and disconnect the sensors, one at a time, to see if any of the sensors causes the power supply
to drop. Replace the defective sensor.
If the sensor supply lines are not correct, check the presence and condition of fuse F6 (15A); replace it if necessary.
Check for the + 12 V supply on connection AP3 between components of component 1222 and 1016. Check for
earth on connection MG between components 1222 and earth MG.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the stored faults.
Follow the instructions to confirm repair.
Deal with any other faults.

NOTES None
After following the instructions, if the fault recurs, switch off the ignition and disconnect the supply fuse from the
parking distance control computer F6 (15A).
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 proximity sensor computer connector (no
damage to the connections).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the ignition switched off, disconnect the parking proximity sensor computer connector to check the
conformity of the feeds and to check the insulation, continuity and the absence of interference resistance
on the following connections:
Connection code AP3,
Between components 1222 and 1016.
Connection code MG.
Between component 1222 and the rear left-hand earth.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the stored faults.

Check that the parking distance control system is activated using status ET003
“Parking distance control” function (parking distance control switch indicator light
off) and check that status ET001 “Reverse gear engaged” shows “YES”.
If the status displays “suspended” or “deactivated”, restart the system by pressing
for 1 or 3 seconds, consult the interpretation of status ET003 “Parking distance
control function”.
Check, when the vehicle is close to an obstacle (between 26 and 150 cm), that the
distance evaluated corresponds to the distance displayed by the diagnostic tool
(PR001 to PR004).
If the distance is inconsistent or if the distance parameters remain at 0 cm, consult
the interpretation of faults DF002 “Left-hand outer sensor”, DF003 “Left-hand
inner sensor”, DF004 “Right-hand outer sensor”, DF005 “Right-hand inner
sensor”.
Check that status ET001 “Reverse gear engaged” is “YES”. Check that the buzzer
volume is not at a zero setting (LC001: ZERO).
If the configured volume is ZERO, reconfigure the computer using command CF001
Buzzer volume. Select the volume setting preferred by the customer (ZERO, MINIMUM,
VERY LOW, LOW, MEDIUM, HIGH, MAXIMUM).
Switch off the ignition, and disconnect the parking distance control computer to check
the insulation and continuity and the absence of interference resistance on the
following connections:
Connection code 151R,
Connection code 151S.
Between components 1222 and 1016.
If the connection or connections are faulty and if there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring or replace it.
Check the condition of the buzzer and that it is operating correctly.
Measure the resistance between the buzzer's two tracks.
Replace the buzzer if its resistance is not approximately 48 ΩΩ Ω Ω
.
If the fault is still present, replace the buzzer.
AFTER REPAIRRepeat the conformity check from the start.

PARKING PROXIMITY SENSOR FUNCTION
NOTESSpecial notes:
If the parking proximity sensor system is suspended or deactivated, the parking
proximity sensor switch indicator light comes on.
This status indicates whether the parking distance control system is on or off:
ET003: READY This means that, when reversing, the parking distance control detects
obstacles and the buzzer sounds (the parking distance control switch
indicator light goes out).
ET003: DETECTING This information is displayed when reverse gear is engaged.
This status indicates that the parking distance control system has
detected an obstacle.
ET003: SUSPENDED This means the parking distance control system is switched off
(no detection possible). The suspension is temporary because the
parking distance control system will come back on after the ignition
is switched off and on. Briefly pressing the parking distance control
switch enables the system to be suspended or reactivated manually.
ET003: DEACTIVATED This means the parking distance control system is switched off
(no detection possible). This suspension is permanent (switching
the + after ignition off and on again will not reactivate the system).
Pressing and holding (3 seconds) the parking distance control
switch enables the system to be deactivated or reactivated.
Check the condition of the fuses F6 (15A), F42 (10A), and replace them if necessary.
If the status does not function as described, check the + 12 V supply on connection LPD between components
1440 and 1016. Check for earth on connection MAN of the connector of component 1440.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for a + 12 V supply on connection AP3. Check for an earth on connection MG of the connector of component
1222.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRRepeat the conformity check from the start.

With the ignition off, disconnect the parking proximity sensor switch to check the insulation (against the earth
and + 12 V), continuity and the absence of interference resistance on the following connection:
●Connection code 151W,
Between components 1222 and 1440.
If the connection is faulty (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, or replace it.
If the connection just checked is correct (no open circuit or short circuit) and there is an earth on connection MAN
of the switch but the fault is still present, check the switch operation with an ohmmeter.
Switch not pressed: insulation between connections 151W and MAN.
After pressing the switch: continuity between connections 151W and MAN.
Replace the parking proximity sensor switch if it fails to function as specified.
AFTER REPAIRRepeat the conformity check from the start.
