Removing

CAUTION:

There is a risk of destroying the transmission control module (Mechatronic) with static discharge.

Before touching or removing the Mechatronics unit, you must first discharge yourself of any static electricity by touching (bare handed) some grounded metal object (for example car, lifting platform).
Never touch contacts in 16-pin connector, as the static charge could destroy the control module and thus the Mechatronic unit.

-- Remove the Mechatronic unit. Refer to MECHATRONIC UNIT .

-- To discharge static electricity, touch the transmission housing (without wearing gloves).

-- Disconnect the connector on transmission by rotating screw connections counter-clockwise -arrow-.
