VI. Air Door Switch option #SCC-AM-SW-00
This option is required for buses equipped with power-assisted doors whose 8-way
warning lamp flasher units are not activated by a mechanical door switch. For these
buses, the SCC monitor will not function when the emergency release valve is used to
dump the air from the system. To determine if this switch option will be required please
perform the following procedure:
 Turn the ignition ON.
 Close the front door.
 Activate the Amber warning lights.
 Open the front door's emergency release valve to dump the air from the system.
 Walk over to the front door
 Manually push the front door open.
 Walk to the outside of the bus and check to see if the Red warning lights have
been activated.
 If the Red warning lights are not flashing, then the air door switch option #SCC-
AM-SW is required (Figure 5)
If the SCC-AM-SW-00 switch is required to be installed, please
follow the instructions below:
COMMON (COM) TERMINAL
BRACKET
NORMALLY CLOSED (NC) TERMINAL
 Remove the panel above the air door.
 Bend and/or twist the switch bracket and firmly mount the SCC-AM-SW-00
switch assembly in a position where the switch's roller arm is fully engaged
when the air door is fully closed. Excessive force applied to the switch's roller
arm can cause damage to the switch. Because of this, the switch bracket
should not deflect more than 1/32" when the roller arm is fully engaged.
 Connect the switch's common (COM) terminal to the SCC monitor's front door
terminal #P8.
 Connect the switch's normally closed (NC) terminal to a chassis ground.
 Close the door and inspect the switch making sure the switch's roller arm is
completely engaged.
 Open the front door and inspect the switch. The switch's roller arm should
spring back to its original resting position.
Follow the procedure in SECTION V to test the air door switch. This will
ensure that it is functioning properly.
