Default Re: WRX FA20DIT failsafe issue

Please explain how do you initiate failsafe on and failsafe off?

1. Check the DR1 jumper is linked
2. Put the jumper link to "DFS" can let me know if stops the CEL.
3. If it doesn't, short out the white and brown wire near the ecu.

Let me know. the above tests are try to establish where the loss of connection lies.

Post a picture of the jumper settings here
