Did the computer guy not only solder the bad joints, but maybe cleaned the contacts while he was in there? I probably would have if I had seen burned joints....

 

I am really not sure all I know is since the fix the check engine light has not come back! I did however get in touch with DJ and he said he would send me a functioning board from another member and I can send him mine.
I still believe there is nothing wrong with mine but who knows...I would assume since it's been 6 days since the fix the light would have come back by now if it was still an issue. However, better safe than sorry I guess

 

Loaner is on its way Nick.

 

Thanks D.J.! You're the man. I appreciate your help with this and looking forward to hearing what you think - whether the relay was functional or not!
Like I said, "mystery no start" has been done on the row of bad joints so that at least should be good to go!

 

I just resoldered my RCM for the second time in 68000 miles. This took the P401 away and the pump runs now - I have relays here in stock, but have not had to change one so far...


Just my two cents. But DJ will fix you up - as has been said before, it is OFTEN the relay contacts.

 

I'm glad everyone on the forum is so helpful. But I'm still 90% sure there is nothing wrong with my RCM as the code has not come back ever since the computer guy fixed the RCM.
However, as far as I know there was nothing done to the actual RELAY, just the broken joints but you know, the guy is pretty smart so he might have cleaned the contacts and that could have fixed the issue!
Looking forward to hearing what D.J. says! But I have to go with what the car has been saying and that is NO P0410 anymore!

I have not experienced any codes but I have been smelling a kind of burnt smell from engine bay, kind of electrical. I googled it and have talked to many and it may have something to do with this secondary air injection system being malfunctioned. Anyone got any ideas?
I will get a new RCM from a dear friend of mine in 2 days so I will wait and mount it.

 

Thanks tighed1

Is there somewhere I can just purchase the relay and do it myself? Ive resoldered it, replaced the inline blue check valve. It was fixed for my 2,000mi trip home from AZ but once the snow melted and I started driving it again the CEL came back on with the same code.

 

I get them here.

AZ970E-1A-12D American Zettler | Power Relays (20 Amps to 99.9 Amps)

They have a $30 minimum order policy.

 

Oddly enough I have a OBD system monitor code for this even though I re-soldered the RCM about 10,000 miles ago. The check engine light does not illuminate but the computer is continuing to monitor the P0410 code when you run a diagnostic.

 

The resoldering generally has nothing to do with the code, what triggers the code is the relay inside the RCM either not making contact due to carbon deposits or the contacts are welded together. The relay needs to be replaced in either case, cleaning the contacts is a short term solution only. If the pump does not run it or the relay may be at fault, if the pump runs all the time the relay contacts are welded together.
If you do not clear the code after fixing the problem or the problem solves itself, the CEL may not come on but the code will remain in the system.
I think I am correct in what I say.

Any pollution test will be failed if the code remains.

 

I can hear the pump activating and then cutting off while operating the vehicle. I passed emissions about 2 months ago. Its showing that the computer is monitoring the code but it is not actually activating the DTC and saying I have an issue with the system. Basically you would not have any idea that the code exists without plugging in the OBD scanner. Currently there are no active codes.

I'm wondering what the mileage or engine cycle duration is to stop monitoring for that code. I can't clear it out because there is no active code to clear.

 

My reader has a similar action, it shows an orange light, meaning that there could be a future, past? problem or something like that. This is only activated on the pollution system.
My car passed with an orange light, seems the CEL has to be on in most cases for failure.

 

There are pending codes and stored codes. Think of pending codes as the issue happened but the computer is monitoring it to see how often it returns to prove it wasn't just a glitch. If the issue continues you will then get the stored code. Some OBDII readers use different terms than pending and stored and some use colored lights.

 

Are you still doing this? I have a 2004 with same code? If you are still doing this what should I do to find the part and get it to you or can I try something before mailing it to you? Thanks

QUOTE=tighed1;517565]I haven't asked what year the RCMs are that I have repaired and to tell the truth until recently I haven't paid attention to the air pump relay.

From now on I will check and if necessary, clean the contacts of all RCMs sent to me for repair.
And hey. No extra charge!

Yup. Still fixin' them!
Sent ya an email.

 

I really feel like a dummy. Been chasing P0410 for 2 or 3 months, replaced solenoid, replaced air pump, checked relay contacts. Problem found ---- Fuse 2 on RCM blown.
Thanks for all the tips and fixes guys & gals.
