Summary of change:
EVAP Subpage of MembersPage/VasilisP AAN ECU serialnr ? '''EVAP valve''' Investigating * if some connection needed (from EC10 or SSC6) ** can you check your EC10 pinout on paper (fill in EC10 section below !) * or if some output is already connected inside ECU to mot55/pin5 Can you '''please measure''' * (ignition off) what is the resistance of the EVAP valve ? * can you measure +12V on one pin of EVAL valve (ignition ON) ? ** please do measure and take note as a verification, (not just write something as "standard") * can you measure connectivity from mot55/pin5 to EVAP valve ? ** [http://www.s2forum.com/forum/showthread.php?t=24073&page=2 drawing] shows mot55/pin3 connected to EVAP, but that must be an error (mot55/3 = fuelpump relay and mot55/5=EVAP, right ?) ---- '''When i test the i259/7 output, the EVAP valve does not operate''' Under misc output 2 settings channel selector I259 channel 7 Under output channel setup, misc 2 has: '''ignition output 7 (7A)Grounding EC36, pin10''' (no conflict, eg. not configured on other output) * as a test: toggle inverted / not inverted checkbox ** can you measure voltage between the EVAP valve pin (whichever is connected to MOT55/pin5) and +12V ? (or +5V can also be used as measurement reference) ---- '''EC10''' Check your EC10 pinout on paper and compare to [http://vems.hu/download/v3/Motronic55/Audi/aan_typical_EC10_pinout.pdf typical EC10 pinout] ? * when misc2=i259/2 and '''toggling inverted / not inverted''' ** please '''measure voltage between EC10/pin8 and +5V''' ** or +4V (WBO2 pump- eg. LSU4.2/pin5 or LSU4.9/pin2) can also be used as measurement reference * same test for i259/3 and EC10/pin9 If the EC10 pin is pulled to GND when i259/.. activated, that can be used for EVAP activation easily * connect to the wire that is verified to be connected to EVAP * a diode (BY399 or min 1n4007) across EVAP valve is nice (cathode to +12V) ---- '''Config''' 1) I have in the aux outputs on my config settings to operate the '''n80 audi valve for recirculating the fuel vapors''' from the engine. * please publish config sometime ** does it pass "validate", or shows some errors ? If yes, can we see and investigate errors, one by one ?
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
