4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of the voltage, resistance and insulation are generally correct, especially if the fault is not
present when analysing (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.
Physical inspection
While manipulating the wiring, 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 their 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 with another wire.
If a fault is detected, repair or replace the wiring harness.

NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Statuses ET704 and ET705 should change status at the same time. If they are inconsistent, consult the
interpretation of fault DF228 Brake signal.
ACTIVE
or
INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
Brake light switch, track 3 Injection computer, connector A,
black, 32-track track E4
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
Continuity between
tracksInsulation between
tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(brake pedal pressed)1 and 2 3 and 4
Replace the switch if the values obtained are not correct.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CHECK
Check the cleanliness and condition of the diagnostic socket contacts which
connect to the vehicle.
Check the condition of the cable from the diagnostic socket to the sensor, and the
cleanliness and condition of the connections.
Check the sensor connections.
Check the condition of the cable from the sensor to the CLIP tool, and the
cleanliness and condition of the connections.
Check the cleanliness and condition of the CLIP socket.
If the fault is still present, contact Techline.
Check the electrical voltage of the battery.
Check the cleanliness and condition of the battery terminals.
Check the condition and tightness of the cable going from the battery + terminal to
the Protection and Switching Unit.
Check the condition of the battery earth cable and ensure that there is a good
electrical connection with the bodywork.
Check the injection computer earth terminal for cleanliness and make sure it is
properly connected to the bodywork.
Check the Protection and Switching Unit's main 30A power supply fuse, plus the
condition and cleanliness of the contacts (see Protection and Switching Unit fault
finding).
Check the injection computer after ignition feed 5A fuse, plus the condition and
cleanliness of the contacts.
AFTER REPAIRRepeat the conformity check from the start.
