Operator Instructions

System Operation

• Display - The OCP uses a graphic display to indicate

the selection for both terrain mode and vehicle load.

Above the selector keys labeled HWY (highway), OFF

HWY (off-highway), and EMER (emergency), an illu-

minated arrow designates the current selection.

• T

errain Selection - The terrain selection is changed

by depressing the desired mode on the keypad.

When the system is actively changing tire pressure,

the arrow above the target mode will flash. Pressing

the key for a current mode will command a pressure

check.

• Loa

d Selection - Vehicle load selection is

represented by an arrow above the rear w

heels in the

graphic display. Depress the keypad

button labeled L/U to change from loaded to

unlo

aded.

Operating a loaded vehicle at unloaded tire pressures may

sult in tire overheating and reduced tire life or blowout.

• Pressure Display

- If the keypad button labeled

Select is pressed after vehicle start, numerical pres-

sures will be displayed sequentially for each active

channel. Subsequent actuation of the

Select key will

lock the display on individual channels, or turn it off

again.

Note: The sys

tem is designed to allow tire pressure increase

due to heat buildup during vehicle use. This system will

not automatically deflate these pressure buildups—

lower pressure mode selection by the operator must be

selected to initiate a deflate.

• Chann

el Indicators - The OCP display includes rings

inside the tires of the truck graphic. The pressure

shown in the display reflects the channel with the

lighted rings.

• Se

rvice Code Indication - The OCP will display ser-

vice codes using a number and letter combination

followed by an excla

mation point (!).

Note: See the Ser

vice Codes Section to diagnose and repair.

• M

etric/English Indicator - The OCP may be pro-

grammed to display pressure in metric (BAR) or

English (PSI) units

(see Programming section).

• RUN F

LAT Indicator - If the TPC System determines

that a tire or tires may not be holding air, it may

reduce the pressure check interval to minimize the

possibility of air loss from the tire by switching to

RUN FLAT operation. (See RUN FLAT in the Key Fea-

tures section).

If RUN FLAT is activated, an asterisk (*) will be illu-

minated in the display of the OCP. This asterisk

matches the symbol on the RUN FLA

T key and it

indicates that the RUN FLAT feature is selected. The

OCP also allows the driver to select RUN FLAT, by

depressing that key, to manually reduce the pressure

check interval. This may be desirable when operating

under conditions (i.e. sharp rocks or construction

debris) where tire punctures may be anticipated. The

RUN FLAT feature will automatically de-select after

10 minutes, but may be re-selected.
