EDITOR'S NOTE: This article replaces "VSA Neutral Memorization Won't Complete," posted in January 2015.
When removing and installing a cable reel, you need to keep both the cable reel and the steering angle sensor in
position. If you don't, the VSA indicator may come on along with one or more VSA DTCs. And when you run the Neutral
Memorization Procedure in the i-HDS, it won't complete.
By the way, this procedure is covered as VSA Sensor Neutral Position Memorization in the service information.

To keep those parts properly positioned, here's a tip: First, make sure the front wheels are pointed straight ahead with
the steering wheel in the straight-ahead position. Then, before removing the cable reel, tape both the cable reel and
steering angle sensor together. This not only keeps the parts properly positioned, but keeps the sensor from accidently
moving.
But what if for some reason the sensor moves? If so, you'll need to manually adjust it. It's an easy process that uses the
i-HDS, but keep in mind it's not included in the service information.
To better understand it, let's take a quick look at steering angle sensor operation. When you turn the steering wheel to
the right (or the sensor clockwise), the reading increases or moves in a positive direction. When you turn it to the left
(or the sensor counterclockwise), the reading decreases or moves in a negative direction.
To manually position the steering angle sensor, you first need to determine its current position with the i-HDS. How you
do that depends on how far along you are with your repair.
For instance, if you've completely assembled the steering column, you'll need to go to the ABS/TCS/VSA Data List and
check the STEERING ANGLE (CAN) value. If you haven't yet installed the steering angle sensor, you'll need to at least
hook up the sensor, the cable reel, and either the airbag assembly or the applicable simulator tool, then read the sensor
value in the data list.

In this example, the STEERING ANGLE (CAN) value is reading a positive 180°, which tells you the steering angle
sensor is 180° out of position clockwise. To fix this, you'll need to remove the sensor from the cable reel and turn the
two tabs 180° counterclockwise to bring the sensor back to center or 0°.
When you're done, you'll then need to install all of the removed components and repeat the Neutral Memorization
Procedure. If you've done the sensor adjustment right , the procedure should complete and you can then move on with
your repair.

Steering Angle Sensor."
