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.

Fault finding - Interpretation of statuses
ET002
SIDE LIGHTS SWITCH
STATUS
DEFINITION–ACTIVE: This status indicates that the side light control is active.
–INACTIVE: This status indicates that the side light control is inactive.
NOTES–Ignition on.
–Side lights on.
If the status of the side light control remains at status INACTIVE, apply the following fault finding procedure.
Check fuse F43 (10A) of the passenger compartment fuse box, component code 1016.
Check that the connection and condition of the rev counter connector are correct (see Wiring Diagram Technical
Note, Twingo II, Component code 995).
If there is a repair method (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair)
repair the connector, otherwise replace the wiring.
Check the + 12 V feed on connection LPG of component 995.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Check the continuity and insulation of:
Connection LPG between the passenger compartment fuse box, component code 1016 and the rev
counter, component code 995.
Connection MAM of the rev counter, component code 995.
Connection MAN of the rev counter, component code 995.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
If the fault is still present, contact the techline.

ALP1 No dialogue with the computer
NOTESNone
Test the diagnostic tool on another vehicle which is in perfect working order.
Check that the sensor's green indicator light comes on.
If communication with the second vehicle is impossible, follow the instructions in the CLIP diagnostic tool test
section.
If dialogue with the second vehicle is possible, follow the instructions in the Vehicle check section.
DIAGNOSTIC
TOOL CHECK
Check the cleanliness and condition of the diagnostic socket contacts on 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 of the battery earth cable and ensure that there is a good
electrical connection with the bodywork.
Check the condition and correct connection of the rev counter connector, component
code 995.
If there is a repair method (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair) repair the connector, otherwise replace the wiring.
Check rev counter supply fuse F18 (15 A) on the passenger compartment fuse box
component code 1016, and the status and cleanliness of the contacts.
Check the rev counter after ignition feed supply fuse F2 (15A) on the passenger
compartment fuse box, component code 1016, and the condition and cleanliness
of the contacts.
