Air Conditioning Compressor Signal and ELS Circuit Diagram

The picture below provides Air Conditioning Compressor Signal (A/C) and Electrical Load Signal (ELS) Circuit Diagram for particularly Toyota cars. The A/C signal used to determine when the air conditioning compressor is loading the engine.

The ELS circuit signals electrical load on the charging system so that the ECU uses the information needed for maintaining a stable idle speed.
