Technical Background

Service
1. Prior to replacing a self-leveling sensor for this condition, inspect each self-leveling sensor for a black colored dot on the body of the sensor
(Figure 1).
Sensors may be marked with more than one colored dot (i.e., a blue dot and a black dot). The black colored dot ensures the latest level part.
-
If sensor(s) are marked with a black dot, the latest part has been installed. Replace only the failed sensor.
-
If the sensors do not have a black dot, replace all 4 sensors with latest version. (See Required Parts and Tools for part numbers.) Prior to
installing new sensors, ensure a black dot appears on the new sensor.
