TECHNICAL INFORMATION
lubrication of drive axle wheel bearings at all
times. Refer to chapter 7, "Care And
Maintenance" under "Wheel Bearing Oil Level".
WHEEL HUB 13017
On vehicles equipped with grease lubricated
wheel bearings, pack with wheel bearing grease.
PRE-HEATING SYSTEM
Depending on options chosen, a Webasto
80,000 Btu coolant heater may be installed on
the coolant circuit. The heater can be used as a
pre-heater or as an auxiliary heat source. Heater
is controlled by programmable 24 hour timer.
See Other Features chapter for information on
how to use the timer.

DDEC IV DIAGNOSTIC CODES
To read the diagnostic codes, a Diagnostic Data
Reader should be plugged into the receptacle
located on the lower side panel of the L.H.
control panel. To read diagnostic codes as blink
codes, momentarily depress the STOP ENGINE
OVERRIDE switch while the ignition is ON, the
engine is idling or shut off. Active codes will be
flashed on the STOP ENGINE indicator light
followed by the inactive codes being flashed on
the CHECK ENGINE indicator light. The cycle is
repeated until the operator depresses the STOP
ENGINE OVERRIDE switch again. For example:
code "43" consists of four flashes, followed by a
short pause, then another three flashes in quick
succession. The following table is a list of the
DDEC diagnostic codes.
