Electric Load Current Sensor On-Vehicle Inspection

Precautions: General safety (00)

Battery Current

Using SUZUKI scan tool

1)When ignition is “OFF”, connect SUZUKI scan tool to DLC.

2)Check that “Battery Current” displayed on SUZUKI scan tool changes to values as electric load increases.

•Non-ENG A-STOP model:

•ENG A-STOP model:

If check result is not as specified, check the following points.

•Electric load current sensor circuits (power, ground and output)
•Battery negative (–) cable
•The following charging system components

—Battery

—Generator

—Generator output circuit
—Generator LIN communication circuit according to Step 2 under DTC U2001:D16AA

If electric load current sensor circuits and charging system are in good condition, replace electric load current sensor (1).

Without using SUZUKI scan tool

1)When ignition is “OFF”, disconnect electric load current sensor connector.

2)Using service wire (1), connect electric load current sensor (2) and electric load current sensor connector (3).

3)With ignition “ON”, check that voltage varies depending on electric load.

•Non-ENG A-STOP model:

•ENG A-STOP model:

If check result is not as specified, check the following parts and circuit.

•Electric load current sensor circuits (power, ground and output)
•Battery negative (–) cable
•The following charging system components

—Battery

—Generator

—Generator output circuit
—Generator LIN communication circuit according to Step 2 under DTC U2001:D16AA

If electric load current sensor circuit and charging system are in good condition, replace electric load current sensor.

Temperature

1)When ignition is “OFF”, disconnect electric load current sensor connector.

2)Connect ohmmeter to electric load current sensor (1) as shown in figure.

3)Check that resistance varies depending on battery temperature as shown in the following graph.
If check result is not as specified, replace electric load current sensor.
