1990timeismoney Posted July 31, 2013 Share Posted July 31, 2013 Hi trying to get a ep82 circuit diagram is there one available or any idea we're to get one.Thanks Quote Link to post Share on other sites
glanzagee Posted July 31, 2013 Share Posted July 31, 2013 Which pat of the diagrame as it comes in sections Part Quote Link to post Share on other sites
1990timeismoney Posted July 31, 2013 Author Share Posted July 31, 2013 The part that shows the resisters I've got one that needs to be replaced but wanna make sure it's rite Quote Link to post Share on other sites
glanzagee Posted July 31, 2013 Share Posted July 31, 2013 no toyota book is going to show you circuit diagram of the ecu sorry if it was the body or engine loom id be glad to scan a few pages out the book Quote Link to post Share on other sites

1990timeismoney Posted July 31, 2013 Author Share Posted July 31, 2013 Thanks mate that would be much appreciated I've attached the link we're u can see the resister worn.any advice or info on the part would be great Quote Link to post Share on other sites
AdamB Posted July 31, 2013 Share Posted July 31, 2013 (edited) What number or marking is on the board mate? I got some diagrams here but I doubt it will be noitceable. Edit.From your pic it looks like number 14? Can't see too clearly though.From the ECU circuit diagram, number 14 has something to do with either the A/C amplifier, believe something to do with air con, or VSV duty, possibly something to do with the original Hi/Lo solenoid. I could be completely wrong though lol. Edited July 31, 2013 by AdamB Quote Link to post Share on other sites

AdamB Posted July 31, 2013 Share Posted July 31, 2013 Unfortunately the wiring diagram doesn't list any resistor values Not the one I have anyway. If you have a standard ecu I would be inclined to open it up and check the resistor values that are either side of your blown one, if they match up with the HRF, I think you will be pretty safe in copying the resistance value from the stock ecu.

1990timeismoney Posted July 31, 2013 Author Share Posted July 31, 2013 Ok mate ill give that ago ill try and buy another ecu and use a original resister. Thanks again.Luke Quote Link to post Share on other sites
