While Hard-Wiring IC Pump- to ground to run all the time,
I accidentally grounded pin 87 on Relay, the "Other Yellow Grommet" Red wire with Green stripe,
Instead of Brown with Blue stripe.
Check engine light/limp mode.
Rewired, correctly.
Disconnected battery, to clear CEL.
Trying to check fuses, Pin 87 at Relay : where does it go? Is there a fuse?
I checked fuses 46, and 87, both 7.5 Amp, in trunk, both are fine.
Thank you
I would think if you blew a fuse in that circuit it would have effect on the operation of the intercooler pump. If your pump is working correctly, I would not worry about it, and should only have 1 "shadow" code for the pump being grounded to short.
Also note that the intercooler pump is a separate system from the rest of the coolant system. It's never crosses into the engine coolant side. It has its own tank under the engine cover in the middle of the engine bay. You will not see IAT temps on your dash cluster, all you see there is oil temps and coolant temps. To monitor IAT temps you will need some sort of logger like hp tuners or something similar.
I personally use a gauge called "banks gauge". Plugs into the obd reader and sees everything the ecu sees. Afr, boost, iat, knock, scans for hard codes and other items.

I think he is still in limp mode - he grounded the power side of that relay so up stream a fuse is blown and is affecting more systems it seems
the shadow code of the grounded ic pump (the mod) has to be removed with a scanner like icarsoft - I don't think a battery pull will get rid of it and will remain while the ic pump is grounded obvi
he wants @Valvestud to offer any schematics or diagrams of this relay circuit
can the op clarify what is the current state of his car?
- in limp mode?
- the CEL code? If there is one - I think you're saying a battery pull didn't get rid of this CEL caused by grounding the wrong wire
- other codes behind the ground fault code for ic?

Here some info.
the relay is labeled as K60.
The power comes from the rear sam fuse box n10/2 from fuse F90 40a via a red wire... however, that spot is blank in the fusebox?
The power goes to the pump via a redblue to the pump m45
The relay is turned on by a the ECU Brnblue wire that gets a ground signal/
The k60 relay gets its switch power from Z7/36 which is labeled "circuit 87 m2e connector sleeve"...... This gets its power from F22 on the rear fuse box, check that next IMO
Im showing the diagram numbers as gf00.19-p-3000-02daa
pe54.21-p-2108-9dad
pe07.08-p-2101-97dae
I also checked my car... on the k60 relay, im getting 12v on pin 30 and 86 i think when the accy on
To answer Peter's questions: can the op clarify what is the current state of his car? - in limp mode?--> I did not yet turn it on, so am not sure. - the CEL code? If there is one - I think you're saying a battery pull didn't get rid of this CEL caused by grounding the wrong wire--> I disconnected Battery 30-40sec, still code. Then 20+ minutes, did not try again to turn on, so am not sure if still CEL code.
- other codes behind the ground fault code for ic? I did not pull up any codes.
I am hoping to "fix" what is wrong, before giving "ignition on".
Am disappointed that Fuses 46, 87 and 90, are all good: would have been simple to sort. Its hard to believe that grounding pin on relay did not cause fuse to blow. Since car works, I am hopeful that no other damage could occur.
Unless more ideas come through, will give it contact and see if CEL is on.
