Critical error "too many current" on Panda EPS

[dallas140cv]

After changing the battery, yesterday I've used FES to delete some errors on ecus of my Panda 1.2. One of them was suprisingly strange: on the EPS, the error screen report a critical error on EPS, but the lamp was not illuminated yet (and the lower screen explain that for this error the alarm lamp will not active), while on the parameter screen I can read in some conditions (also with stopped steering wheel, in various positions) "too many current" as motor current. During steering, instead, the current level is OK. What have I to do for this error? The EPS seems work correctly....
