Inspection

Initialization and diagnosis sequence by using diagnostic equipment

Below content summarize the procedure for A/S using Diagnostic equipment

Download Parameter
1.

Select "AFLS" menu after selecting a vehicle.

2.

Select "Parameter download" menu for define a characteristc of vehicle.

3.

Select the LHD/RHD and MT/AT option refer to the vehicle options.

4.

When "Parameter download" is done,display belows.

System Calibration
caution

This menu is applied only if vehicle has a Steel suspension

1.

Select "AFLS" menu after selecting a vehicle.

2.

Select "Sensor initializing-Non ECS" if vehicle has a Steel suspension

3.

When "System calibration" is done,display belows.

4.

When "System calibration" is not done,display as belows.

Actuator Test

When it replace H/Lamp Unit, it necessarily check up by operating actuator test.
