FIGURE 6-10. BATTERY CONNECTION
After Replacing the Battery
While replacing the battery, the backup power source
for the memory inside the payload meter is momentar-
ily disconnected.
This can allow unwanted data (garbage) to enter the
memory and affect the meter's recognition proce-
dures. The following will remove this unwanted data.
1. Turn the keyswitch to the ON position.
may flash.
2. Using the Operator Check Mode, set the speed
limit option code, time and date. (These were
erased from memory when the battery was dis-
connected).
3. Without turning the keyswitch to the OFF position
advance to the start position. With the engine
running, the display:
4. Perform the Calibration procedure.
Refer to Page 15.
5. Load the truck to the rated payload, or close to it.
Dump the load.
6. Move the truck to a safe area, wait at least 5
seconds after dumping the load, then shut the
truck down.
7. Turn the keyswitch back to the ON position but do
not start the engine.
8. Perform the Data All Clear in the Operator Check
mode.
9. Forcibly clear the data for the total payload and

SUSPENSION PRESSURE SENSOR
The pressure sensors are mounted on top of each
suspension. The sensors produce a voltage signal
from 1 -- 5 volts output.
The pressure sensor is mounted to the suspension
cylinder using a Schrader Valve assembly, adapter
and sensor. The sensor can be replaced without re-
leasing the pressure in the suspension by removing
the sensor with the adapter.
Removal
Make certain the adapter and sensor are removed
together from the valve assembly. Removing the
complete valve assembly or just the sensor may
result in the component being forced out of the
suspension by the gas pressure inside.
1. Disconnect sensor from truck wiring harness.

Note: The Schrader valve in the valve assembly
will prevent gas from escaping when adapter

escape, recharging of the suspension will be
required.
