b. Check operation of switch as follows:
Select driver's mirror and operate joystick up and down, checking that voltage on
common
line toggles between ground and +12V and that voltage on driver's mirror
U I D line toggles in opposition ie when common = +12V, driver U / D = ground
and vice versa. Repeat test moving joystick left and right and monitoring common line
against driver
R / L line; the same results should be achieved. Select passenger mirror
and repeat both tests on passenger mirror lines.
