Removal and installation of the central control unit of the comfort system "J393"
Instructions: When replacing the central control unit for comfort systems "J393", it is essential to read its coding "Replacement/coding of the central control unit for comfort systems "J393".
Switch off the ignition and all electrical consumers, remove the ignition key. Remove the glove compartment. Press the locking lever "1" of the mount "2" of the central control unit of the comfort system "3" in the direction of "arrow A". At the same time, move the central control unit "3" in the mount "2" by approximately 5 mm in the direction of "arrow B" to the first locking position.
Instructions: For clarity, the central control unit of the comfort system is shown in the following figure in a removed state. The plugs can only be unlocked and disconnected if the "arrow" grooves of the plugs and the holder exactly match.
Unlock and disconnect the "arrow" connectors from the central control unit for the comfort system "J393".
Instructions: The number of plugs depends on the vehicle configuration. All plugs can only be installed in one position, therefore, marking the plugs is not required. Central control unit of the comfort system "J393" "2" initially remains in holder "3".
Unclip the holder "3" from the fasteners "1" and remove it "3" in the direction of the "arrow".
Press the locking lever "3" in the direction of arrow A and at the same time move the central control unit of the comfort system "J393" "2" in the direction of arrow B from holder "1".
Installation is carried out in the reverse order. Insert the central control unit of the comfort system "J393" into the holder first only in the first locking position, so that the grooves of the "arrow" of the plug and the holder are located exactly one above the other. Install the connectors "arrows" Place the holder "3" together with the connected control unit "2" on the locks "1". Insert the control unit "2" into the holder until the connectors are locked until they stop (second fixation position).
