AUTO MODE WITH Battery Charger:VAS5908
Special tools and workshop equipment required
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
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.
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.
OR
-- 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.
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.
