Disconnecting
-- Switch off the ignition and electrical equipment.
-- Place the vehicle key and other start authorization systems (such as smartphones) outside of the vehicle interior.
Vehicles with refrigerant R744
Danger of suffocation by the refrigerant R744
The vehicle interior carbon dioxide concentration sensor is not active during procedures at the vehicle with disconnected 12 V battery.
- Only perform procedures in the vehicle interior with open doors.
-- Mind the safety precautions when working on air conditioning systems.
Continuation for All Vehicles
-- Open the negative terminal cover above the battery monitoring control module -3-.
-- Loosen the nut -1- several turns and remove the battery monitoring control module -3- from the battery negative terminal.
-- Check the voltage of the 12V vehicle electrical system using a commercially available voltmeter.
- The voltage must be 0V.
Vehicles without de-energized vehicle electrical system
-- Refer to the appropriate Service Information .
-- Check the voltage of the 12V vehicle electrical system using a commercially available voltmeter.
- The voltage must be 0V.
Continuation for All Vehicles
Risk of damaging the positive and negative terminal battery clamps and of the battery terminals.
- The positive and negative terminal battery clamps must only be attached by hand and without force.
- Do not put any grease on the battery terminals.
- The positive and negative terminal battery clamps must be installed in a way that the battery terminal is flush with the battery clamp or stands out.
-- Attach the battery monitoring control module -3- onto the battery negative terminal.
-- Tighten the nut -1-.
-- Refer to BATTERY MONITORING CONTROL MODULE -J367-, ADAPTING
-- Switch the ignition on.
-- Open and close the door windows all the way.
-- Then, with the windows closed, pull the door window regulator switch until the relay audibly switches.
-- Check the convenience closing from the window regulator motors.
- When the "convenience function" is activated, the door windows must close without holding the window regulator button.
