Fault symptoms

Poor heating of cabin

Heater not permitted to start

Conditions

The heater has made 10 failed start attempts.

Diagnostic help

The heater is provided with extra cabling and connector which is isolated from the ordinary cabling from the heater. This cabling and connector is not used but is connected to the control module, therefore always check that this cabling is undamaged before beginning fault tracing.

Note also that in the ordinary cabling between the heater and the 8-pin connector, there is an extra light green lead that is cut and is not used.
