A/C Switch

WARNING: This page is about a different car, the 1987 Toyota Supra. However, it is still accessible from the selected car via links, so may be relevant.

A signal is sent to ECU when the air conditioner is activated. The ECU requires this input for controlling idle speed during A/C operation.
