Re: Engine light check - Smog Check purgatory
¿ªÔÆÌåÓýThanks Christoph ¨C I am still learning/looking for a solution. Do you (or anybody) know which pin from the ECU I need to find? According to what I saw on Busaru.com, it should be part of connector F47, pin 19. Attached is the document from which I got this information. Check the bottom of the second page of this PDF ? If I have located this pin correctly (hard to know the orientation of the connector on the ecu), it has a red/yellow wire currently connected. A similar red/yellow wire can be found in the main VW cluster connection, but it is for coolant heating (per cluster images and VW information available), not anything to do with the CEL. ? I tried checking for voltage at that ECU pin, but got zero reading. This could be operator error (me!) as I am not sure the volt meter lead was getting any electrical connection in the first place. It¡¯s a small opening, and the red/yellow wire is firmly seated within it. Not much room for a volt meter lead. I¡¯ll try again later today. ? Thanks for the advice and knowledge. Am soaking it all up as fast/best as I can. ? tc ? ? ? From: [email protected] <[email protected]> On Behalf Of Christoph Pistor

Just like Wayne says you need to run a long wire from the ECU CEL pin to the LED in the dash. You really want that also to check error codes. Just because the light is not on does not mean you don't have any error codes. this is a good site to understand which codes are allowed at the SMOG and which are not: ? ? Christoph ?
