Steering Angle Neutral Position Learning: Procedure

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 .

1. Steering Angle Neutral Position - Learn

   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. Do the VSA sensor neutral position memorization .

   NOTE:  When the VSA sensor neutral position memorization is performed, the current position is cleared and overwritten.
