Washer Fluid Light

TEST CONDITION(S)
1. Ignition 3 voltage is present

FAILURE CONDITION(S)
1. Low washer fluid level exists for at least 15 seconds

ACTION TAKEN.
1. Display the Washer Fluid telltale on the IPC

DESCRIPTION.
The BCM provides system voltage to the low washer fluid circuit, and the washer fluid level switch provides the single path to ground. The BCM supplies and internally monitors the voltage level of the circuit at pin 2A6 (BI09). When the washer fluid level circuit is open the BCM will detect system voltage. but if the washer fluid level switch provides a path to ground (low washer fluid condition present), the BCM will detect low voltage. If this condition exists for at least 15 seconds, the BCM will turn on the Washer Fluid light on the IPC.

DIAGNOSIS
