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, one using the HDS and the other without the HDS.
• The learning cannot be done when the EPS indicator is on.

1. Steering Angle Neutral Position - Learn

   Without using 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 slope road.

     • -

       Rapid acceleration and deceleration.

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

   2. Be sure the indicators do not come on.

   With using the HDS 

   1. Do the VSA sensor neutral position memorization .

   NOTE:  VSA sensor neutral position memorization for VSA system is performed, the steering angle neutral position is cleared and overwritten.
