SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
Short-Circuit to battery on wiring to
component
Faulty wiring, faulty heater relay (K27-K31),
defective heating valve (Y31),
broken element in heating.
Open Load on wiring to component
relay defect
relay not connected wiring harness broken
problems with supply voltage

Action
Check wiring, component
Disconnect plug from heating valve (Y31) and
reset fault.
If fault is still present you have to look in the
wir- ing of Y31 to the control unit Pin A:92.
If error is no longer present, you have to check
the wiring of Y31 via relay K31
and possibly the heating cables and relay
(K27- K30).
