The auxiliary code identifies the fan
(1: Auxiliary fan 1, 2: Auxiliary fan 2).
An auxiliary cooling fan (connected to
the fan connectors on the control unit)
is stuck or disconnected.

hardware.
Make sure the front cover of the drive
module is in place and tightened.
Check auxiliary fan(s) and
connection(s).
Replace faulty fan.
Check safety circuit connections. For
