•
Electrically-adjustable steering column adjustment is restricted and does not adjust vertically.
•
Incorrect operation of Easy Entry is not the cause. It is unlikely that external forces have led to the loss of the
stored end positions of the adjustment movement. See TSB 2015819, 48 Easy Entry function of the power
adjustable steering column intermittently does not work , for more information.
•
Seat adjustments can be used to maintain the 10-inch minimum recommended distance from the steering wheel
in case of airbag deployment. The axial adjustment is still functional during this condition.
Technical Background
The steering column may be under tension due to unfavorable tolerances of the steering column and module cross
carrier. As a result, the current draw of the regulator motors is above specification, which causes the electric
steering column adjustment to fail. Once the vehicle electrical system control module, J519 (address word 09),
detects an excessive current draw, the basic settings will be erased. If basic settings are not stored in the vehicle
electrical system control module, the module will not send voltage/current to the motor to operate the vertical
adjustment.

Checking the electrically-adjustable steering column
1. Remove the steering column trim to gain access to the 8-pin (black) connector located under the dash.
2. Identify wires on T8d/1 and T8d/5. Install the current pick-up clamp around these wires (Figure 1).
Note:
Current will only flow on one wire at a time (up/down), so the current clamp can be placed over both wires.
Current will only flow after basic settings have been set in the central electrics control module, J519.
Figure 1. Current clamp installed (left), pins 1 and 5 (right).
3. Perform basic settings of the steering column in the J519 control module. Record the peak current values during
the length and height adjustment.
•
The expected current draw in correct steering columns is about 1A for axial adjustments and about 2.8A 3.4A for vertical adjustment (lower current draw typically found during testing, 2.0A-2.5A). Current draws
above these values are an indication of binding or a tight steering column.

4. Loosen the steering column from the cross carrier, then tighten the
column according to ELSA instructions (Figure 2). This should
relieve any tension between the steering column and cross carrier,
if any existed.
Figure 2. Tightening sequence (see ELSA
for correct torque specifications)
5. Operate the steering column up and down and note the peak current draw:
•
If the current draw is lower and within the specifications after the mounting bolts have been loosened and
retightened, the steering column had tension. If the current draw stays low after the reinstallation, the tension
is only caused by the installation. An adjustment of the steering column is not necessary.
•
If the current draw rises to its original level after the reinstallation, the tension is caused by unfavorable
tolerances of the components. The steering column must be adjusted as described in the instructions that
follow.
Adjustment of the steering column to reduce belt tension
Tip: Changing the tension of the belt drive may lead to an increased noise level during adjustment of the
steering column.

1. Loosen the belt cover of the steering column:
•
If necessary, remove the footwell and steering column
covers.
•
Next, move the height adjustment of the steering
column to a central position.
•
Then, carefully loosen the side clips without damaging
the clasps (Figure 3).
Note:
Do not disconnect the wiring harness at the side on the
cover attachment.
Figure 3. Side clips.
2. Carefully remove the gear belt from one gear wheel, using
a fine screwdriver (Figure 4). Leave the gear belt removed
from one wheel for step 3.
Figure 4. Remove the gear belt with a fine
screwdriver.
3. Reduce the tension in the steering column:
•
Mark the gear’s original location on the gear, on the
housing, and on the belt (Figure 5).

Place the original marking of the gear in the center of
the two greatest resistance markings (Figure 8).
Figure 8. Placing a green dot in between the two
yellow dots and turning the gear (red dot) to match
the green dot on the housing.
4. Place the gear belt, by hand, on the gear wheel (Figure 9).
Note:
The gear may have to move slightly to engage the belt
during installation but other than that, the gear and green
dot should line up (+/- ½ tooth). This will ensure that the
gear is now centered between the two greatest resistance
points.

5. Carefully reinstall the cover on the housing (Figure 10).
Figure 10. The cover, installed on the housing.
6. Perform the basic settings:
•
First, re-program the steering column with V.A.G. scan tool in the basic settings for the electronic central
electrics module, J519.
•
Next, verify that the changing current values during length and height adjustment are no greater than
specification (2.8A - 3.4A).
•
Perform a function check.
7. Reassemble the steering column.
8. Verify the proper function of the adjustment.
9. If concern is still present or there is excessive noise in the column, the column may need to be replaced. Please
continue diagnosis of the steering column and follow ELSA instructions for further diagnostic steps and claiming
information.
