 Charge Air Cooler Relay Circuit

The ECU controls the CAC fan with the CAC fan relay. A circuit
breaker is installed on the fan’s power circuit to prevent fan /
electrical system damage in the event the fan becomes jammed
or obstructed. The circuit breaker will reset itself when given
time to cool down.
