1.DEF : Communication disrupted
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.
Special note:
Default value PR145 Engine coolant temperature = 20 ˚C
Use the Wiring Diagrams Technical Note for New TWINGO.
Run a multiplex network test (see 88B, Multiplex).
Run a check of the injection system (see 17B, Petrol injection).
Check the connection and condition of the connectors of components 120 and 119.
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 connection and condition of the coolant temperature sensor connector (component code 244)
integrated with the injection system.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
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.

PR145
ENGINE COOLANT TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the coolant temperature in ˚C.
NOTESNone
Engine stopped, ignition on
PR145 = 20 ˚C in default mode
Compare the value of parameter PR145 with the value measured by the coolant temperature sensor in the
domain of the injection computer (see 17B, Petrol injection).
If not correct, run a multiplex network test (see 88B, Multiplex).
AFTER REPAIRCarry out another fault finding check on the system.
Deal with any other faults.
Clear the stored faults.
