Actuator Test - Each time the cluster is put through the actuator test, the odometer OLED will display all of its segments simultaneously during
the OLED portion of the test to confirm the functionality of the OLED and the cluster control circuitry.
The PCM continually monitors the vehicle speed pulse information received from the wheel speed sensors, then sends the proper messages to the
ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).
For proper diagnosis of the wheel speed sensors, the PCM, the EMIC, the CAN data bus or the electronic communication related to odometer operation a
diagnostic scan tool is required. Refer to the appropriate diagnostic information.
