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.

Inspection procedure

Hint:

  1. Inspect battery current sensor assembly

  1. Disconnect the b29 battery current sensor connector.
  2. Measure the resistance of the battery current sensor.

Standard resistance


Hint:

The resistance differs according to the tester type.



  1. Check harness and connector (battery current sensor - ecm)

  1. Disconnect the b29 battery current sensor connector.
  2. Disconnect the b30 ecm connectors.
  3. Measure the resistance of the wire harness side connectors.

Standard resistance (check for open)


Standard resistance (check for short)
