Lane Keeping Assist Steering Intervention Fault

on 2014 Ram 2500 6.7L I6 Cummins Diesel · 4WD

What this code means

The lane keeping assist system cannot apply corrective steering through the EPS system.

Symptoms

  • LKA disabled
  • Lane keep warning light
  • System available in warning mode only

Common causes

  • EPS fault preventing LKA torque application
  • Steering torque sensor error
  • LKA module communication fault
  • Steering angle sensor not calibrated

Diagnostic steps

  1. Check for EPS trouble codes
  2. Verify steering angle sensor calibration
  3. Test EPS torque application capability
  4. Check CAN communication between LKA and EPS modules
  5. Inspect steering system for mechanical issues

Repair notes

Resolve EPS faults first. LKA requires a fully functional EPS system to apply corrective steering.
