Toyota RAV4. Battery current sensor circuit


Description

Toyota RAV4. Battery current sensor circuit


The battery current sensor installed on the positive (+) battery terminal detects the amount of current supplied from the generator.

The battery current sensor changes current to voltage (at the positive (+) battery terminal) and sends it to the ecm. The ecm controls the voltage of the generator based on the signals from the battery current sensor.
