Veröffentlicht Oktober 10, 200816 j Kalibrierung Klimaautomatik Quellthread: http://www.saab-cars.de/showthread.php?p=333598#post333598 Hier der Weg, die Klimaautomatik zu kalibrieren: 1) Motor starten 2) Die Tasten "Auto" und "off" gleichzeitig drücken 3) Es erscheint im Display eine "0", das Display wird heller, die Motoren der Luftklappen werden hörbar gestellt. 4) Zum Abschluß stellt sich das Display wieder zurück auf die normale Helligkeit und auf die ursprünglich eingestellte Temperatur. 5) Sofern ein Fehler vorliegt, wird er vor dem Zurückschalten in den Normalzustand in Form einer Ziffer angezeigt. Der Range reicht von 1 - 23. Wenn jetzt noch jemand beitragen kann, wo die Erklärung zu den Fehlermeldungen zu finden sind, wäre die Zusammenfassung für die KB komplett. Viele Grüsse Thomas

Oktober 10, 200816 j Autor Tech 2 Hinweise zu Fehlermeldungen Klimaautomatik ... und hier wird es noch detaillierter. Die Fehler, die den gleichen Tech 2 Hinweis enthalten, sind nicht nochmal erläutert. Fault Code Defective function/component Malfunction Tech2 Code __________________________ 1 Control module Internal control module malfunction Fault symptoms: ACC panel does not function B1605 __________________________ 2 Cabin temperature sensor Open circuit or short to B+ Fault symptoms: Perceived temperature in cabin too high or too low compared to the set temperature. Conditions The following conditions apply: • Open circuit or short to B+ on pin 20 >4.9 V. • Short to ground on pin 20<0.1 V. • Measured every 440 ms and 5 consecutive measurements are required to set a diagnostic trouble code. • The diagnostic trouble code is deleted after the ignition has been switched on 20 times if the malfunction conditions have not been fulfilled. • When the diagnostic trouble code is set, the control module uses a default value. When the ignition is turned on, the outside temperature is used as a default value and after that, a mean value of the calculated temperatures at head height for the front seat passenger and the driver is used. B1350 __________________________ 2 Cabin temperature sensor Short-circuit to ground B1350 __________________________ 3 Solar sensor Open circuit or communication error Fault symptoms: Perceived temperature in cabin too high or too low compared to the set temperature. Conditions The following conditions apply: • Open circuit or communication error. • The solar sensor sends an identification pulse continuously, 5V-0V-5V. The control module searches for identification pulses during time periods of 440 ms. When five successive measurements have been made with no pulse pattern, a DTC is generated. • The diagnostic trouble code is deleted after the ignition has been switched on 20 times if the malfunction conditions have not been fulfilled. • When the diagnostic trouble code has been generated, the control module uses a default value, that being the latest valid value. When ignition is turned on, 0 W/m 2 . Diagnostic help Check that a value is obtained from all 5 directions. B1340 __________________________ 4 Mixed-air temperature sensor, LH Open circuit or short to B+ Fault symptoms: Perceived temperature in cabin too high or too low compared to the set temperature. Conditions The following conditions apply: • Open circuit or short to B+ on pin 19 >4.9 V. • Short to ground on pin 19<0.1 V. • Measured every 440 ms and 5 consecutive measurements are required to set a diagnostic trouble code. • The diagnostic trouble code is deleted after the ignition has been switched on 20 times if the malfunction conditions have not been fulfilled. • When the diagnostic trouble code is set, the control module uses the default value, which is the relative opening of the air-mixing flap in question multiplied by the coolant temperature. B1345 __________________________ 4 Mixed-air temperature sensor, LH Short-circuit to ground B1345 __________________________ 5 Mixed-air temperature sensor, RH Short-circuit to ground Fault symptoms: Perceived temperature in cabin too high or too low compared to the set temperature.
