Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

This code here can be a short in wiring or the steering angle sensor at fault or the VSA modulator control unit at fault.The diagnostic procedure below does have to be followed to pinpoint which component is at fault and then repaired from there.This has to be done with special test equipment.But you can follow it yourself to pinpoint this issue or have another facility do the diagnostic testing to pinpoint the issue.

DTC 64: Sensor Power Voltage

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch OFF, then disconnect the HDS.
4. Test-drive the vehicle around a number of corners.
5. Check for DTCs with the HDS.

Is DTC 64 indicated?
