Pedal Percentages and Meter Calibration

The following procedures are used to calibrate the
retarder and accelerator pedals, retarder lever, and the
hydraulic brake temperature and propel system tem-
perature gauges and the speedometer for the soft-
ware. If any of the above components require
replacement during truck servicing or troubleshooting
procedures, the new or rebuilt component must be
recalibrated using the applicable procedure before the
truck is returned to service.
1. Connect the serial communication cable from the
PTU to the PSC port, behind the center console
on the driver's side.
2. Turn keyswitch and Control power Switch ON.
3. Enter the following on the PTU:
¤ c:\>ACNMENU {enter}
¤ Highlight "PTU TCI & PSC" {enter}
¤ Type your name {enter}
¤ Type your password {enter}
¤ Cursor to "Normal Operation" {enter}
¤ Cursor to "View/Set PSC Analog Outputs" {enter}
A: Retard Pedal:
¤ Cursor to the box in the "#" column on channel
one {enter}
¤ Type in: 359 {enter}
1. Parameter name will be rpinhi_ail5.
Record the parameter value with the retard
pedal fully released. (typical value; 1.50
volts).
Record the parameter value with the retard
pedal fully depressed. (typical value; 9.50
volts).
B: Retard Lever:
¤ Cursor to the box in the "#" column on channel
two {enter}
¤ Type in: 344 {enter}
1. Parameter name will be retlever_ail4.
Record the parameter value with the lever
up (typical value; 0.0 volts).
Record the parameter value with the lever
down (typical value; 8.75 volts).
