NOTE:

If software updates or flash campaigns/actions are performed on a vehicle, a charger with at least 70A charging current must be used in order to avoid problems during software updates and flash campaigns/actions.

Battery Charger "VAS 5903". Refer to Battery Charger .

Battery Charger "VAS5908". Refer to Battery Charger .

The >>AUTO MODE<< serves to maintain the voltage in the vehicle electrical system (retention charge) during flashing or diagnostic procedures, for example. With integrated load detection, the Battery Charger:VAS5908 recognizes if a battery or an electrical consumer is connected with resistive load when in >>AUTO MODE<<.

Starting Power Supply

NOTE:

If the charging clamps are connected to an electrical consumer or a battery before turning on the charger, the Battery Charger:VAS5908 will start automatically after turning it on with maintenance charging in >>AUTO MODE<<.

-- Switch the Battery Charger:VAS5908 on.

-- With the ←↓ buttons, select AUTO MODE and confirm with the ENTER button.

-- Connect the red charging clamp "+" to the vehicle battery positive terminal.

NOTE:

On vehicles with a Start/Stop system and an installed Battery Monitoring Control Module -J367-, the black charge terminal "-" must be connected to the body ground.

When connecting to the battery negative terminal, the Battery Monitoring Control Module -J367- is bypassed. Malfunctions in the Start/Stop System may be the result.

-- On vehicles with a Start/Stop System, connect the black charging clamp "-" to the body ground.

-- On vehicles without a Start/Stop System, connect the black charging clamp "-" to the vehicle battery negative terminal.

-- Connect the charging clamps on the electrical equipment with an resistive load.

-- Select START in the menu using the ←↓ buttons and confirm with ENTER to start the supply.

NOTE:

The Battery Charger:VAS5908 automatically adapts to the thresholds of power and voltage for the auto mode.

Ending Supply

-- Select STOP in the menu using the ←↓ buttons and confirm with ENTER to stop the supply.

-- Switch the Battery Charger:VAS5908 off.

-- Disconnect the black charging clamp "-" on the battery charger from the vehicle battery negative terminal or from the electrical equipment.

-- Disconnect the red charging clamp "+" on the battery charger from the vehicle battery positive terminal or from the electrical equipment.

-- Remove the power supply plug.
