Fault finding - Interpretation of statuses
ET002
FRONT WIPER PROTECTION
NOTESSpecial notes:
Only apply the checks if the status is ACTIVE or BLOCKED.
If the status is ACTIVE, this indicates that after a wiping request, the Protection and
Switching Unit has detected abnormal operation for more than 6 seconds
(constrained or blocked).
If the status is BLOCKED, this means that the total duration of intermittent pauses is
greater than 2 minutes.
The status returns to INACTIVE as soon as the UCH requests another wiping setpoint
(wiper control adjusted, or request by the rain sensor).
Use Wiring Diagrams Technical Note for Mégane II or Scénic II.
Make sure that nothing is mechanically blocking the movement of the wiper arms (blades stuck, condition and
assembly of the wiper mechanism linkage and that there are no objects that could impede the movement of the
mechanism).
Check that the wiper mechanism is not seized.
Repair if necessary.
Check the condition and connection of connectors CT1 and CN on the Protection and Switching Unit,
component code 1337.
If the connectors are 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 windscreen wiper motor connector, component code 212.
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 insulation, continuity and the absence of interference resistance on the following connections:
–14M between components 1337 and 212,
–14L between components 1337 and 212,
–14K between components 1337 and 212.
If the 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 REPAIRRepeat the conformity check from the start.
