Troubleshooting
For effective troubleshooting and repairs, there must be
a good understanding of the electrical circuits and com-
ponents used on the Sonic Boom System (see Sonic
Boom System Operation in this chapter).
NOTE: When troubleshooting an electrical problem on
your Sonic Boom System, refer to informationregarding
the sonic boom light in this section. Also, use the Diag-
nostic Display (see Special Tools in this c hapter) to test
electronic control unit (ECU) inputs and outputs.
Sonic Boom Light
The Sonic Boom System is designed to automatically
adjust the sprayer boom height ifchanges inthe turf sur-
face are detected. The sonic boom light should be illumi-
nated wheneverthe vehicle ignition switch isON and the
sonic boom switch is in either the automatic or manual
position.
The sonic boom light flashing quickly indicates that the
Sonic Boom System is in the calibration mode. This
mode allows the spray booms to be adjusted for the de-
sired boom height.The calibration modelasts for twenty
(20) seconds after which the boom light should quit
flashing.
NOTE: A sequence of switch movements is necessary
to engage the calibration mode. Refer to the Sonic
Boom Kit Installation Instructions for this sequence.
The sonicboom light flashing slowly indicatesthat a sys-
tem error has been encountered. If the boom light is
flashing slowly, lower the affected boom(s) with the
boom actuator switch(es) to clear the error. If the error
continues, there may be an issue with the Sonic Boom
System electronic control unit (ECU). If this occurs, see
Diagnostic Display and Troubleshooting Chart in this
section.

Sonic Boom Calibration
The Sonic Boom sensor calibration process is critical to
the correct operation of the Sonic Boom System. The
calibration process establishes the sensor target dis-
tance between the boom and the turf surface. Typically,
this distance is approximately twenty (20) inches. Steps
needed for proper calibration are identified in the Sonic
Boom Kit Installation Instructions.
While calibrating the Sonic Boom sensors, it is best to
perform the calibration process on turf. A shiny surface
(e.g. cement shop floor) can skew sensor signals. Also,
ensure the calibration area is free of buildings, trees, un-
derground plumbing and other machines that could in-
terfere with sensor signals.
