ERRORS DISPLAY

This screen page shows potential errors detected
in the vehicle (ATT) or stored in the control unit
(MEM) and it allows to check error clearing (STO).

Notes
Electrical fault in sensor or cable harness
Faulty sensor or signal interference
Possible tone wheel fault due to deformations or
dirt; possible alterations on the wheel bearing sur-
face. In very rare cases, abnormal tone wheel
vibrations
Faulty sensor or missing sensor/tone wheel or ex-
cessive distance between the sensor and the tone
wheel or tone wheel with wrong number of teeth
Faulty sensor or missing sensor/tone wheel or ex-
cessive distance between the sensor and the tone
wheel
Faulty sensor/tone wheel, or tone wheel with
wrong number of teeth or wrong tyre size
