NOTESConditions for applying the fault finding procedure to a stored fault:
Insert the card into the card reader, switch on and switch off the engine leaving the
card in the card reader. Carry out fault finding on the card reader circuit with the card
in the card reader (after the engine is switched off, the card reader is supplied and
controlled for 20 min).
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
CC.0
NOTESNone.
Check the condition and connection of the card reader connector (tabs bent, broken, oxidised, etc.).
If the connector is 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.
Check the condition and connection of the PE2 and PE1 connectors of the UCH (tabs bent, broken, oxidised,
etc.).
If the connector is 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.
Ensure the continuity and insulation from earth of the following connections:
●Connection code 26BG,
●Connection code 26BD,
●Connection code 26BH.
Between components 645 and 1082.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Using the oscilloscope, check for a square pulse signal on connection 26BH of the card reader connector:
Connect the oscilloscope between connection 26BH of the connector and a bodywork earth.
Set the oscilloscope as: Calibration at 5 V/division
Time base 100 ms/division
Check for a square pulse signal from the UCH on connection 26BH of the card reader connector.
If there is no signal, replace the UCH.
If there is a signal, replace the card reader.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
