Operator Instructions
• Service Code Indication - The DDM will not display
service codes directly but will exhibit two dashes if
service is required. (Accessing the service codes will
require a diagnostic tool).
Note: See the Service Codes Section to diagnose and repair.
• RUN FLAT 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, the DDM will alternate the
display of the terrain setting and RF and the CHECK
TIRE indicator will be illuminated.
Tire Pressure Control System
Programming
Spicer's Tire Pressure Control System is fully programmable,
allowing the technician to program tire pressures for each
channel (axle group) and maximum speeds for each terrain
mode. If equipped with the Driver Display Module (DDM),
programming must be done with a diagnostic tool.
Programmable settings include:
• Individual pressure settings for the front, rear, and
trailer axle groups.
• Loaded and unloaded axle group programming for
highway, off-highway, and emergency conditions.
• Over speed warning threshold for highway,
off-highway and emergency conditions.
