Check for continuity between the terminals in each switch position according to the table.
NOTE:
- Make sure the correct test lead (+ or -) is placed on the terminal.
- When checking for continuity across the diode, use the diode setting (→-) on the digital volt/ohm meter to check the diode bias.
- Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).

If the continuity is not as specified, replace the switch.
Install the parts in the reverse order of removal.
