Actuator Test - Each time the cluster is put through the actuator test, the washer fluid indicator will be turned
on, then off again during the LED portion of the test to confirm the functionality of the LED and the cluster
control circuitry.
The FCM continually monitors the washer fluid level switch in the washer reservoir to determine the level of the
washer fluid. The FCM then sends the proper lamp-on and lamp-off messages to the instrument cluster. For further
diagnosis of the washer fluid indicator or the instrument cluster circuitry that controls the indicator, (Refer to 8 -
ELECTRICAL/INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING).
For proper diagnosis of the washer fluid level switch, the FCM, the CAN data bus, or the electronic message inputs
to the instrument cluster that control the washer fluid indicator, a diagnostic scan tool is required. Refer to the appro-
priate diagnostic information.
