Diagnostic – Failures interpretation
DF119
MEMORIZED WINDSCREEN WIPER FIX POINT STOPPING
Diagnostic application conditions to the memorized failure:
RECOMMENDATIONS - failure declared present further to wiper control
REMARK: wipers random operation in timing position
(timing non-respected)
Check that fix point stopping state ET 005 is active each time when wipers blades reach the
pause position and then pass to inactive.
Check the branching and the state of connectors of the Cockpit Central Unit.
Replace the connector, if necessary.
Check the insulation , continuity and absence of parasite resistance of lines:
Pin A6 of UCH connector P1 pin 2 windscreen wiper motor
Mass pin 1 windscreen wiper motor
Fix if necessary.
Check connection and condition of the connector of the windscreen wiper motor
Check the windscreen wiper motor
Check the windscreen wiper mounting
Replace, eventually, the wiper motor.
Apply the recommendation
AFTER REPAIRING Fix all others failures
Erase the memorized failures.
