Sensor electrical conformity
Check the continuity and absence of interference resistance of the following connections:
–3LR between components 120 and 921,
–3LS between components 120 and 921,
–3LT between components 120 and 921,
–3LU between components 120 and 921,
–3LW between components 120 and 921,
–3LV between components 120 and 921.
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.
