Digi klíma nefúka-nové poznatky 2.

[julinosms]

tak som sa s tym dneska pohral. po štarte klima vzdy funguje.zopne ventilator aj kompresor klimy,trva to nejaku tu chvilu,fuka fajny studeny vzduch(skusal som na LO),potom nieco cvakne,ventilator na chladici sa prestane tocit rovnako aj kompresor vypne.akonahle vypnem klimu na ovl.paneli a vypnem aj motor,nasledne zastartujem a zapnem klimu tak zas nejaky cas funguje az dokym sa sama nevypne.potom sa uz ani na x-ty pokus nezapne,treba vypnut motor a cely postup opakovat..
som objednany na diagnostiku v mercedese,som zvedavy ci sa nieco najde..

Tu som našiel niečo čo by ti mohlo pomôcť: http://www.mercedesforum.com/forum/show ... php?t=5306" onclick="window.open(this.href);return false;
podľa tejto diagnostiky by mali tie tvoje čísla znamenať Coolant Circulation Pump (A31m1) a Left Duovalve (Water Valve) (Y21y1). V preklade to znamená že je niečo s obehovým chladiacim čerpadlom a ľavým dvojventilom (vodným ventilom). Snáď som to správne preložil :)

Diagnostika, ktorú sem dal Fusion je síce na dig. klímu ale vraj "tlačítkovú" teda tú ktorá sa montovala do roku ´95. Tá klíma ktorá má už veľký display a vyzerá ako autorádio by mala mať síce rovnaký diagnostický program, ale čítanie kódov je vraj trochu pozmenené.
Diagnostika novších klím by mala byť nasledovná:

FAULT DIAGNOSIS STEPS
1. IGNITION : Turn to Position 1
2. Temperature selector : set to "LO"
3. Within 20 seconds press the REST and DEFROST buttons simultaneously for more than 5 seconds.
4. The LED in the RECIRCULATE button flashes and "dI A" appears on the display.
5. Press the AUTO button until all DTC's are displayed and recorded.
6. The current faults are displayed first, then the intermittent faults. "END'" is displayed when all codes have been displayed.
7. To erase codes press v and ^ simultaneously for more than 5 seconds. The display will then show "---". Press AUTO to cancel the erase.
8. IGNITION : OFF to end the test program.
