Battery Charger :VAS5095A SUPPORT MODE
Special tools and workshop equipment required
- Battery Charger :VAS5095A
General Information
The support mode provides the vehicle electrical system with voltage when the Battery -A- is removed or disconnected.
For more information. Refer to the :VAS5095A Operating Instructions.
The support mode is used for the following situations:
- Vehicle electrical system support mode with the Battery -A- not installed
- Maintaining the voltage when the battery is being replaced
- Systems test without the Battery -A-
Risk of injury. Follow all warning messages and safety precautions. Refer to WARNINGS AND SAFETY PRECAUTIONS .
Do not check or charge a Battery -A- when the visual indicator has >>no color or is bright yellow<<. Jump starting must not be used!
There is a risk of explosion during testing, charging or jump starting.
These Batteries -A- must be replaced.
Procedure
- The polarity protection of the charger clamps is not active in the operation mode "charging severely discharged batteries/Support mode". Connect the charger clamps to the battery terminals correctly according to polarity!
- It can result in sparks due to short circuit.
- This constitutes an explosion risk.
- Make sure the charging clamp connections are secure.
-- Remove the Battery -A-. Refer to BATTERY, REMOVING AND INSTALLING .
Whenever the Battery -A- is removed, be careful to prevent contact between the connected charge clamp on the positive terminal and the body ground. Likewise prevent contact between the battery terminals.
-- Clamp the red charging clamp (+) to the vehicle positive battery terminal.
On vehicles with a Start/Stop function and an installed Battery Monitoring Control Module -J367-, the black charge terminal (-) must be connected to the body ground. The Start/Stop system will malfunction when it is connected to the Battery -A- negative terminal.
-- Attach the black charging clamp (-) to the vehicle battery negative terminal.
-- Check the setting for the support mode/standard operation switch. Refer to Battery Charger . It must be set to "support mode".
-- Check correct polarity connection of charger clamps.
-- Switch on the :VAS5095A . Refer to Battery Charger .
The :VAS5095A starts the support mode.
End the Battery Support Mode
-- Switch off the :VAS5095A . Refer to Battery Charger .
-- Remove the charging clamps from the battery terminals.
-- Disconnect the :VAS5095A from the power.
