NOTE: Initial calibration of the Sonic Boom sensors is
required for proper operation of ECU inputs. Refer to
your Sonic Boom Kit Installation Instructions for infor-
mation on initial sensor calibration.
NOTE: Right and left side Sonic Boom sensors are
identical so they can be exchanged to assist in trouble-
shooting. If a problem follows the exchanged sensor,an
electrical problem likely exists with the sensor. If the
problem remains unchanged, something other than the
sensoristheproblemsource(e.g. switch, circuit wiring).
