00778 Steering Angle Sensor Defective

Fault code 00778 Steering Angle Sensor Defective is set in steering column electronic or ABS control module. when there is any changes occurs in reading or steering angle sensor. Steering angle sensor usually turn 360 degree right and 360 degree left. When there is any changes occurs at this 360 degree while turning steering left or right. Control module set fault code 00778 Steering Angle Sensor Defective.

Steering control module use steering angle sensor to turn steering. When driver turn steering , steering angle sensor turn accordingly. Steering control module recieve this turning signal of steering angle sensor and actuate steering motor to turn steering. If in any case steering angle sensor is not sending any signal of steering control module, steering control module will not actuate steering motor to turn steering, due to which steering operation will become hard to turn.

00778 Steering Angle Sensor Defective

Causes of 00778 Steering Angle Sensor Defective:

  • Faulty steering angle sensor.
  • Blown fuse.
  • Faulty ride height control module.
  • Damage wiring harness.
  • Faulty steering control module (electric steering).

Symptoms :

  • Traction warning light will illuminate on cluster meter.
  • Hard Steering operation.
  • Fault code will store.
  • Steering warning light will illuminate on cluster.

How to trouble shoot :

  • When found this fault code mechanic need check reading of steering angle sensor. With the help of scan tool check reading of steering angle sensor if it is working fine or not. If reading of steering angle sensor is moving while turning steering. Than it might be possible that angle sensor is good. It need to be perform calibration or basic setting which can be remove this fault code from control module.
  • CASE #2If in case scan tool is not able to read steering angle sensor reading than it might be possible that angle sensor is faulty. replace faulty steering angle sensor that will solve problem.
  • Than turn steering wheel full right and check reading of steering angle sensor, do same with turning steering towards left side. From both the side steering angle sensor reading should be same.
  • if reading of angle sensor from both the side is same than remove angle sensor out side and aligned it to centre position than again fit it and perform calibration. If after aligned steering angle sensor it show fault code that mean steering angle sensor is faulty.
  • CASE #3Sometime faulty ride height control module also creat this fault code. ride height control module is located at rear trunk. there is also a fuse box, check all the fuses and relay if found any falty fuse replace it. if all fuse and relay is good than replacing height control module can solve problem.

Solution of 00778 Steering Angle Sensor Defective :

  • Replace blown fuse.
  • Repair damage wiring harness.
  • Replace faulty steering angle sensor.
  • Perform steering angle sensor calibration.
  • Replace faulty ride height control module.
