NOTE! If the car has a passenger compartment ventilation filter the control module must be programmed with this information. This causes the control
module to increase blower fan speeds and the air flow to compensate for the resistance from the filter unit. If the control module is not programmed for a
ventilation filter when there is a filter installed, the air flow will be reduced as will the efficiency of the demisting of the interior of the windows, however
the noise levels from the blower fan will be slightly lower. If on the other hand, the control module is programmed for a passenger compartment
ventilation filter and the filter is not installed, this will cause a higher air flow which can make demisting of the interior glass easier, but also gives a
slightly higher noise level.
Remove the cover panel over the blower fan air intake to determine if the car has a passenger compartment ventilation filter installed.
Use the Programming function to read off and program the ECC control module. Programmable data is: with or without passenger compartment
ventilation filter. If the control module was not previously programmed no data can be read off.
Read off if a passenger compartment ventilation filter is programmed. Make a note of the reading. If the programming is not correct, program in the
Any further programming to do?
