Scheme 6: SHOCK ABSORBER SOLENOIDS

Type

Damper solenoids: Wire wound solenoids that regulate valves in the shock absorbers.

characteristic

Damper solenoids: Resistance between terminals #1 and #2 should be approx. 5 ohms at +20 °C.

Resistance decreases with increasing temperature.

Other information

In the event of a fault in the Four-C system, the dampers function as standard passive dampers.
