E85 Heating/Air Conditioning System

AA ccaamm mmeeaassuurreemmeenntt ((rreeffeerreennccee rruunn))

takes place the first time the control panel/control

module is operated after:

• Replacing the control panel/control module

• Replacing the cam disc

• Interruption in power supply

During this reference run, the length and distances of both cams with respect to each other

are measured and stored in the control module. A fault code is stored if cam referencing

cannot be concluded successfully after 3 attempts. In this case, adjustment of the central

kinematics for air distribution is possible only within restricted limits.

IHKS Principle of Operation

Blower

When KL15 is switched “ON”, the blower is activated in linear progression from 0 to 8 Volts

(depending on the selected blower speed). When the blower is switched “OFF” (zero posi-

tion) the IHKS is deactivated in addition to the following:

• Blower switched off

• Fresh air/recirculating air flap closed

• Mixed air flap closed (to ensure the heat exchanger does not unnecessarily heat up the

heater/air conditioner)

• Compressor switched off

NNoottee::

Rear window defogger can still be activated

Temperature Control

1. Evaporator

2. Mixed air flap

3. Heat exchanger

4. Stepper motor, mixed air flap
