●Connection code 14G (low speed windscreen wiper control) between components 645 and 145.
●Connection code 14H (high speed windscreen wiper control) between components 645 and 145.
●Connection code 36E (rear screen wiper timed control) between components 645 and 145.
●Connection code MAN or MAN between component 145 and the earth MAN (left-hand drive) or MAM
(right-hand drive).
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 problem persists, replace the wiper stalk (component code 145). (See MR 411 mechanical systems 84A,
Controls - Signals, Wiper switch: Removal - Refitting).
AFTER REPAIRRepeat the conformity check from the start.
Carry out fault finding on the system.
