VSA DTC Troubleshooting: 27-12, 27-13
DTC 27-12: Steering Angle Sensor Stuck
DTC 27-13: Steering Angle Sensor Output Signal Malfunction
NOTE:
This DTC may set if the vehicle is driven on a lift (wheels are turning) and the steering wheel is turned significantly. This is normal, ignore it.
Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.
