Idle Stabilization Control Unit: Vanagon

The idle stabilization control unit is located in front of the right-hand taillight assembly. If engine idle speed differs from the value stored in the idle stabilization control unit, the idle air stabilizer valve adjusts the volume of air entering the engine at idle. The idle stabilization control unit receives information from the following:

Coolant Temperature Sensor
ECU Control Relay
ECU
Oxygen Sensor
Power Steering Oil Pressure Switch

NOTE: Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by the control unit. The second category covers OUTPUT SIGNALS, which are components controlled by the control unit.
