ACCESS 1 Display
ACCESS 1 display messages and menus can be ac-
cessed from three levels of authorization:
1. Operator Level
2. Service Level - Level 2 (Full Truck Operation)
3. Service Level - Level 3 (No Truck Operation)
Typical navigation button usage: up and down arrows
will scroll through menu choices, right arrow will enter
a menu and left arrow will exit the current menu. The
enter/return button is used to select a function or
choice.
Operator Level
The operator level is accessed by turning the key
switch ON. The operator may choose from the follow-
ing menus (provided a higher priority message is not
active and the necessary features menus are enabled):
• Message (for example Bdi = 70%)
• Pressure (option - the truck must be equipped with
PVAR and F20 Pressure Regulator feature menu
must be enabled)
• Hour
• Events
• Service
• Performance
• Setup Relief Pressures (F20 Pressure Regulator
and F21 User Pressure feature menus must be en-
abled)
The following messages will be displayed in order of
priority (if enabled), regardless of operator selection:
1. PM Due
2. User Code
3. Event Code
4. Return throttle to neutral
5. User selected message
If any message is more than eight characters it will be
scrolled across the display from right to left.
After power up, the display will always show RC 5500
regardless of which menu was selected prior to power-
ing down the truck. To change the message displayed
after power up, enter the Message Mode and select
one of the other choices. A more detailed Message
Mode explanation follows.
