The Battery Monitoring Control Module -J367- will be called battery monitoring control module in the information that follows.
Battery -A- will be called battery in the information that follows.
Disconnecting
-- End the drive ready mode.
-- 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
Risk of suffocation due to refrigerant R744.
During procedures on the vehicle for which the 12 V battery is disconnected, the vehicle interior carbon dioxide concentration sensor is not working.
- Only perform procedures in the vehicle interior with open doors.
-- Pay attention to the safety precautions when working on A/C 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.
-- Disconnect the connector -2- from the Battery Monitoring Control Module -J367-.
-- Wait 1 minute.
-- Check the voltage of the 12V vehicle electrical system using a commercially available voltmeter.
Conditions
- The voltage must be 0V.
Vehicles with a voltage greater than 0V
-- Refer to HIGH-VOLTAGE SYSTEM, DE-ENERGIZING .
-- Check the voltage of the 12V vehicle electrical system using a commercially available voltmeter.
Conditions
- The voltage must be 0V.
Continuation for all vehicles
Connecting
Risk of damaging the positive and negative battery terminal clamps and of the battery terminals.
- The battery terminal clamps for the positive terminal and negative terminal must only be attached by hand and without force.
- Do not put any grease on the battery terminals.
- The battery terminal clamps for the positive terminal and negative terminal must be installed in a way that the battery terminal is flush with the battery terminal clamp or stands out.
-- Attach the battery monitoring control module -3- onto the battery negative terminal.
-- Tighten the nut -1-.
-- Connect the connector -2- from the Battery Monitoring Control Module -J367-.
-- 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.
Conditions
- When the "convenience function" is activated, the door windows must close without holding the window regulator button.
