NOTESPriorities when dealing with a number of faults:
If fault DF062 Multiplex line fault is present or stored, deal with it first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the computer fault memory has been cleared, the
ignition has been switched off and on again and the engine has been started.
Use the Wiring Diagrams Technical Note for New TWINGO.
Run a multiplex network test (see 88B, Multiplex).
Run fault finding on the injection system (see 17B, Petrol injection).
Check for the presence, condition and correct positioning of the 15A fuse for the brake lights in the passenger
compartment fuse box.
Check that the indicator light switches off quickly as soon as the brake pedal moves.
Check the connection and condition of the connectors of components 120 and 160.
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check the adjustment of the brake light switch on the pedals.
Check for continuity with the pedal depressed, between connections AP10 (track 2) and 65A of component 160.
Replace the switch if necessary (see MR 411 Mechanical systems, 83D Cruise control, Brake light switch:
Removal - Refitting).
Check there is no continuity with the pedal released, between connections AP10 (track 2) and 65A of
component 160.
Replace the switch if necessary (see MR 411 Mechanical systems, 83D Cruise control, Brake light switch:
Removal - Refitting).
Ensure the insulation to + 12 V, to earth and the continuity of the following connections:
●Connection code 3MT,
●Connection code 3MS,
between components 120 and 119.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any faults detected by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
