NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present after a road test using the cruise control then the speed limiter
function.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Disconnect the battery.
Disconnect the injection computer.
Check the cleanliness and condition of the injection computer connections, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Using the Universal bornier, check for insulation and continuity on the following connections:
●86G between components 120 and 331,
●86M between components 120 and 331.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

of capacity). The customer is complaining that the air conditioning is operating
continuously.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the condition of the UPC connectors, component code 1337.
Check the condition of the engine management computer connector, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run a test on the UPC computer (see 87G, Engine compartment connection unit).
