5. FAULT FINDING LOG
You will always be asked for this log:
●when requesting technical assistance from Techline,
●for approval requests when replacing parts for which approval is mandatory,
●to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY ADVICE
Safety rules must be observed during any work on a component to prevent any damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the appropriate tools, IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS
CARRIED OUT.

PRESENT
OR
STOREDSENSOR SUPPLY VOLTAGE
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.

NOTESNone
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.
AFTER REPAIRCarry out a complete check using the diagnostic tool.
