Make sure that the wiring harness "3" of the ELV control unit "J764" "1" when moving the steering column, it does not get pinched or touch sharp edges.





Observe the installation sequence: Insert the mounting tabs "1" of the steering column into the mounting holes on the central pipe. Tighten all bolts, but do not tighten them. First, tighten bolt "2" to the specified tightening torque. Then tighten bolt "3" to the specified tightening torque. Then tighten bolt "4" and bolt "5" to the specified tightening torque. If present, install the right energy absorbing element in the driver's side footwell. Lastly, tighten bolt "6" and bolt "7" to the specified tightening torque. Tighten bolt "8" and bolt "9" to the specified tightening torque. When replacing the steering column, replace nut "10".



Place the intermediate steering shaft "3" on the steering column "1" as far as it will go and tighten the bolt "2". Install the steering column switch module (SMLS). Install the steering column trim.

Checking the steering column for damage

External inspection: Check for damage to steering column parts.

Functionality check: Check for jamming and ease of rotation of the steering column. Check for easy adjustment of the steering column in length and height. Check for absence of pipe movement "in the direction of arrow A" or "in the direction of arrow B".



If the pipe moves, the steering column should be replaced.
