Klima Relay questions (1986)
I've done some research in the archives on the Klima Relay. However I want to make sure that the following is correct...
To activate the compressor, output 87 is given +12V
(it's a bit unclear wheter the compressor is engaged with +12v or a ground signal).
Is the output 87z put to +12v to signal the ECU to increase the idle? Alternatives are +5V TTL-level or a ground signal..
The Klima relay being analyzed has part # 002 545 13 05.
