Idle Validation Switch

Idle Validation Switch
The idle validation switch signals the PCM that the accelerator pedal is in the idle position.

A PCM detected/ETC IVS Switch will illuminate the Malfunction Indicator Lamp. An inoperative ETC/IVS Switch detected by the PCM will only allow the engine to run at idle.
