Re: Wiring for Check Engine Light
Below is an old post from this group that may help you.
It is slightly trimmed and from the old yahoo group. Mark -------- Forwarded Message -------- Subject: Re: Wiring for Check Engine Light Date: Mon, 26 Jun 2017 22:36:09 -0400 From: Larry A Rich, I don't know what KEP tells you about the check engine light; Having said all that, I will tell you what I feel is relevant. The most important info you need is what pin on the ECU goes to the CEL on that year and model. You should be able to find this out from the files on our group site or on sites that are linked to. That pin on the ECU goes low (to ground) when the ECU wants to turn on the CEL. Thru a resistor, that pin needs to be connected to the LED that you use for the CEL. You did not mention whether you want to install it in the instrument cluster or near the ECU. In any case you need to connect the other end of the LED to a source of +12V that is on when the ignition is on. Such a source of 12v can be found on the instrument cluster or on the wires supplying the ECU. The resistor in the circuit is needed to prevent the LED from being overloaded by too much current. I would use something like 500 to 800 ohms, 1/2 watt or 1/4 watt. The LED will light only when it is connected in the right direction. You can check this using a 9V battery if you wish, again using the resistor to limit the current. Good luck, Larry A. |
Re: Engine light check - Smog Check purgatory
开云体育Thanks Christoph – 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

Re: Engine light check - Smog Check purgatory
开云体育There would only be a trans code if the ecu is from an automatic. You can get rid of that code too by grounding the single wire from the ecu for the auto trans.? On Jan 18, 2024 6:50 a.m., Richard W Stratford <daritysden@...> wrote:

Re: Engine light check - Smog Check purgatory
All you have to do is run a wire from ecu to dash, power up an led with ignition and ground with ecu wire. if you read the kennedy EO label, they expect the light to be on with transmission codes. Super easy and not worth tampering with the system, I would catch that and fail you. Richard Stratford ?

Re: Engine light check - Smog Check purgatory
It goes like this:? drive to your friendly Star Station, you say I need a Smog Check.? First question they ask:? What year is your vehicle?? You tell them, and they tell you:? "Well, our equipment for that is down right now, might be another week for repair."? So you schlep off to Station #2, and Station #3....and you get EXACTLY the same response!? Finally, you get smart, call around, ask if they have WORKING equipment; their response if lucky is "Yes; you got the BAR sticker?"? And then it all happens, finally.? Folks, this is extremely frustrating....but it is what it is.

Since you are in Paso Robles, and California Westys is in San Diego, how about a quick call to Ceasar there?? He might tell you where to look.? I just got smogged at a Star Station in the San Diego area; I went to 3 shops....all of them said "equipment is down".? Went to a 4th one and passed.?
