OPERATOR’S MANUAL
Accessory Sensors
Voltage readings of accessory sensors relate to voltage feedback from
specific sensors in their current position. When sensor position changes,
the voltage reading changes.
–
A zero (0) voltage reading indicates a faulty sensor or bad
connection.
Ground Speed Frequency
Ground Speed Frequency identifies the pulses per second coming into the
control module and could indicate a potential problem with the module, not
reading a signal from the sensor, or a speed sensor failure.
Voltage Readings
Voltage readings from the truck battery are displayed for the following:
–
Solenoid Power (voltage from battery to solenoid relays)
–
Solenoid Ground (voltage from battery to solenoid relays)
–
ECU Power (voltage present at rate controller module)
–
ECU Ground (voltage present at rate controller module)
