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, Low tire pressure/TPMS 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 on a straight section at speeds above 9 mph (15 km/h) until indicators go off.

   NOTE: 

   • If the indicators go off, the learning is completed.
   • When drive the vehicle on stable straight, the learning will complete for about 10 seconds.
   • Difficult situations for learning are below:
   • • -

       Driving on a non straight section.

     • -

       Driving on a rough road.

     • -

       Driving in 9 mph (15 km/h) or less.

     • -

       Driving on a sloped road.

     • -

       Rapid acceleration and deceleration.

   • If the learning does not complete, check the EPS system.

   2. Be sure the indicators do not come on.

   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.
