Substitute Value 

  • ABS function not affected.
  • Anti-spin function blocked.

Possible Source 

  • Anti-spin control in action too long.
  • Brakes on too long (brakes have been used so much that brake disc temperature has become too high).

Fault symptom[s]

  • Anti-spin warning lamp lit.
  • Anti-spin does not function.
    NOTE:

    Anti-spin function is deactivated until brake disc temperature is below 350°C (662°F).
