Question

the main electronic components in a fan hydraulic system are:
□ 1) diverter valves
□ 2) ecm
□ 3) fan speed control valve solenoid
□ 4) reversing solenoid

Explanation:

In a fan hydraulic system, the main electronic components typically include ECM (Engine Control Module, which can manage fan - related functions), fan speed control valve solenoid (to control fan speed via hydraulic valve actuation), and reversing solenoid (for reversing functions). Diverter valves are more hydraulic - mechanical components rather than electronic. So the correct options are 2) ECM, 3) Fan speed control valve solenoid, 4) Reversing solenoid.

Answer:

1. ECM, 3) Fan speed control valve solenoid, 4) Reversing solenoid
