–Connection code 60AF between components 756 and 1029.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Use the "universal bornier" to check the continuity of the following connections:
–Connection code 60AJ between components 756 and 1029,
–Connection code 60AF between components 756 and 1029.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
