4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

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.

PARKING DISTANCE CONTROL SWITCH
NOTESSpecial notes:
Only apply the interpretation of this status if the position of the parking distance control
switch is not consistent with the information supplied by status (“Brief press” or
“Released”).
There must be no present or stored faults.
Check the condition of fuses F6 (15A), F42 (10A) and replace them if necessary.
Check that there is a + 12 V supply on connection LPD between components 1140 and 1016. Check that there is
an 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 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.
With the ignition off, disconnect the parking distance control button connector to check the insulation (against
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 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 connection just checked is OK (no open or short circuit), and there is an earth on track A2 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.

Try the diagnostic tool on another vehicle.
Check:
–The connection between the diagnostic tool and the diagnostic socket (lead in good condition).
–The injection, engine and passenger compartment fuses.
Check the condition of fuses F6 (15A) and F11 (20A) and replace them if necessary.
Check that there is a + 12 V battery feed on connection BP19 of the diagnostic socket. Check that there is an
earth on connections MAM and NAM of the diagnostic socket.
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 for a + 12 V supply on connection AP3. Check for 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.
Switch off the ignition, and disconnect the parking distance control computer 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 components 1222 and the MG earth.
●Connection code HK between components 1222 and 225.
●Connection code BP19 between components 225 and 1016.
●Connection code NAM between components 225 the earth NAM.
●Connection code MAN between components 225 and earth MAN.
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 Techline.
