Battery Current Sensor: Inspection

WARNING: This page is about a different car, the 2007 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT BATTERY CURRENT SENSOR

Inspect the resistance.

Measure the resistance between terminals 1 (VIB) and 2 (GIB).

Standard resistance

TERMINALS RESISTANCE SPECIFICATION

Tester Connection	Resistance
Positive probe to terminal 1 (VIB) Negative probe to terminal 2 (GIB)	3.5 to 4.5 kΩ
Positive probe to terminal 2 (GIB) Negative probe to terminal 1 (VIB)	5 to 7 kΩ

If the results are not as specified, replace the battery current sensor.

Measure the resistance between terminals 1 (VIB) and 3 (IB).

Standard resistance

TERMINALS RESISTANCE SPECIFICATION

Tester Connection	Resistance
Positive probe to terminal 1 (VIB) Negative probe to terminal 3 (IB)	3.5 to 4.5 kΩ
Positive probe to terminal 1 (VIB) Negative probe to terminal 3 (IB)	5 to 7 kΩ

If the results are not as specified, replace the battery current sensor.

Measure the resistance between terminals 2 (GIB) and 3 (IB).
Standard resistance:

0.2 kΩ or less

NOTE: Even if the probes are changed around, the resistance will not vary.

If the result is not as specified, replace the battery current sensor.
