Assembly
Check the cover open switch for
proper mechanical operation. If
incorrect, repair as necessary.
Disconnect the cover open switch
cable from J4 at the engine board
and measure the voltage at J4-3. It
measures approxi5 V dc. If
the voltage is incorrect, replace the
engine board. If the voltage is
correct, check the voltage at J4-1. If
the voltage measures greater than
+1.0 V dc, replace the engine board.
If the voltage is correct, check the
continuity between J4-1 and J4-3 on
the cable. If no change in continuity
occurs as the switch is activated,
replace the cover open switch/cable
assembly. If the continuity changes
as the switch is activated, replace
the engine board.
