Steering Angle Neutral Position Learning

NOTE:
If the steering angle neutral position is cleared, do the steering angle neutral position learning procedure.
The steering angle neutral position is cleared whenever you do any of these actions:
?
EPS motor/control unit replacement, removal, or installation.
?
12 volt battery terminal is disconnected from the 12 volt battery.
?
The power is disconnected from the EPS control unit.
?
The power supply voltage for the EPS control unit is decreased.
If the steering angle neutral position is cleared, the VSA indicator, VSA OFF indicator, deflation warning system indicator, and CMBS indicator (if equipped) will come on.
There are two learning methods.
The learning cannot be done when the EPS indicator is on.
If the learning does not complete, check the EPS system.

Learning method without the HDS
1.
Drive the vehicle in a straight line at speeds of 10 mph (15 km/h) or more until the indicators go off.
NOTE:
The learning will complete after driving in a straight line for about 10 seconds.
Difficult situations for learning are below:
?
Driving on a non straight line.
?
Driving on a rough road.
?
Driving under 10 mph (15 km/h) or less.
?
Driving on a sloped road.
?
Rapid acceleration and deceleration.
2.
Check that the indicators go off.


Learning method with the HDS
1.
NOTE: When the VSA sensor neutral position memorization is performed, the current position is cleared and overwritten.
