2)If white cable is not visible through the product's 10 O' Clock Neutral Check Window, then manually adjust the setting to neutral.

Neutral Check Window : Normal	Neutral Check Window : Fault
White cable is visible through 10 O' Clock Neutral Check Window	White cable is not visible through 10 O' Clock Neutral Check Window

6.Clock spring manual neutral setting procedure.

(1)Press the Auto Lock at 6 O' Clock and turn clockwise 3 rotations.

(2)Press the Auto Lock at 6 O' Clock and turn counter-clockwise 3 rotations.

(3)If white cable is visible through the 10 O' Clock Neutral Check Window, then the spring is set to neutral.

7.Install the steering wheel column shroud and the steering wheel.(Refer to Body - "Steering Column Shroud Panel")
