4.2 Sensor Level Check Procedure
To achieve an accurate alignment, it is important that the sensors hang level when the
sensor lock knob is loosened. A sensor must be balanced correctly to hang level.
To check the balance of a sensor:
Mount the sensor on a wheel adaptor.
Mount the wheel adaptor onto a wheel without connecting the sensor cable.
With the sensor lock knob loosened, wait until the sensor does not rock on
the wheel adaptor.
Observe the level in the sensor.
If the bubble is in the center of the level, as shown below, the sensor is
balanced.
NOTE: A level reminder icon will appear on the vehicle plan view
indicator when a sensor is severely out of level.
BUBBLE
If the bubble is off to one side of the level, as shown below, the sensor must
be adjusted to restore the sensor to level.
BUBBLE
To balance sensors, loosen the screws securing the weight to the toe arm. Slide the
weight in the proper direction to center the bubble in the level.
