Power steering Control Module
In the previous example we looked at
diagnosing an ignition switch using the Tech 2.
Now lets take a quick look at diagnosing the
electronic stability Control (esC) system. All
vehicles, 2011 and newer, must be equipped
with the esC system. however, this system was
widely used starting in 2008. What does this
mean to you? It means that if you are
performing alignments on vehicles, you must
check the steering angle sensor PID and
ensure that it is reading 0° with the steering
wheel centered.
For our subject vehicle the steering angle sensor PID is located in the Data Display section of the
Power steering Control Module option. you can see that in the screen capture the tool is
currently reporting the steering Wheel Position at 0°.
If after you have performed an alignment and
you find that the steering angle sensor is not
reading 0° with the steering wheel centered,
you will need to reset the sensor.
To reset the sensor you need to enter the
special Functions option at the steering main
menu.
