I'm impressed with all you guys and this complicated diagnosis. Where does one send an ECU for repair, and where do they start? My wife and I have torn enough plastic valances / spoilers / bumper covers off on parking blocks that we're very wary of them. Hello. There are a number of companies that ...

DonnonGT I checked my Alldata on my 2005 and it has pretty detailed pinouts on the ECM - enough to give you the data on where the 5V to the throttle assembly is etc. That info is out there, my 2005 is different than your 2004 though. If you are stuck, I could add a sub to the 2004 and send you the ...

As far as the trans, I suspect the symptoms "-" on the dim with hard engagement may be part of limp mode when a major problem in engine management is detected. I've never seen a full pinout of the TCM connector. I wouldn't be surprised if the +5v VREF generated by the ECM is also fed to t...

Ugly. We don't have a lot of troubleshooting info inside that box.

Thanks again for your help.

The list of codes present and circumstances I'm thinking it may have shorted the +5v reference voltage to either ground or +B and damaged the 5v regulator circuit inside the ECM. I'm not sure how well protected the ECM is against dead shorts on that. If you have a voltmeter, probe the brown wire at...

Yep. They all came Back in less than five minutes.

Sorry Don, I read but did not comprehend. That’s a tough one. If you can find a wiring diagram and post I’ll try to sort out some thoughts What I am afraid of is that the shorts did some damage in the ECM and probably the TCM. Although, if all the sensors, modules and such now throwing codes are da...

Disconnect the battery and splice solder these back together and you will be fine. Look up NASA splice if you have enough slack. Remember heat shrink and a loom to protect when done. I did disconnect the battery and splice them. The car would not start at all before. After I repaired the wires the ...

Hello. I have a 2004 Volvo S60 T5. Until a couple of weeks ago, it was a great running car, with no issues or trouble codes. I went out to eat one night and bumped the curb at the front of the parking place. The curb hit the front of the crossmember, but didn't hit very hard. I turned the car off an...
