NOTESSpecial note:
To display this fault as present or stored, run command
AC016 Electrical supply circuits test.
Use Wiring Diagrams Technical Note for Mégane II or
Scénic II.
Check that UPC fuses F8 (25A), F12 (20A) and F20 (20A) are correct.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–BP14, between components 1337 and 118,
–BP42, between components 1337 and 997,
–BP42, between components 1337 and 119,
–BP27, between components 1337 and 449.
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.
If the fault is still present, contact the Techline.
AFTER REPAIRRun command AC016 Electrical supply circuits test.
Clear the computer fault memory, switch the + after ignition supply off and back on, and
run another check with the diagnostic tool.

NOTESSpecial notes:
Check the condition and connection of fuse 21 (15A) on the Protection and
Switching Unit. Replace it if necessary.
The headlight washer pump operates if the dipped headlights are lit and the
windscreen washer switch is pressed and held.
Use Wiring Diagrams Technical Note for Mégane II or Scénic II.
Check the condition and connection of the headlight washer pump component code 219 (tabs bent, broken or
oxidised).
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 connector.
Check the condition and connection of the Protection and Switching Unit connector (tabs bent, broken, or
oxidised).
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 connector.
To check that the pump is working properly, supply the pump's tracks directly in one direction and then the other.
If the pump does not rotate, replace it.
Check for + 12 V alternately on connection code 39C of the headlight washer pump connector.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–39A, between components 1337 and 219,
–39C, between components 1337 and 219.
If the connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
