One week old s300 burnt

[cilcil88]

Hi guys so I went to start my civic today and it started but ran horrible. Shut it off and connected my laptop to the ecu but couldn't get a connection. Pulled the ecu out and smelled the burnt smell. Upon further looking I found the actual s300 board had a burnt spot on it. Im looking to assistance to see if this can be repaired? This has been in my civic for about a week with no issues at all and then bam

That is not repairable and is not covered under warranty as something is wired improperly for it to cause it to burn like that.

Send an email to support <at> hondata.com with the following and I will issue an RMA and give you further

No offense but how would this be a wiring problem if it has not had any issues and all of a sudden this happens. Ecu also has no sign of any damage or burnt. Also how would this not have any warranty being brand new?

I'm also going to see if my selling dealer can help me out before I assume I'm sh*$ out of luck

Also just for information purposes I put my old chipped p06 ecu and it started/runs with no issues. Checked all grounds and power wires with no problems. Also no codes for anything either

This is from a fault with the internal power supply in the ECU. It either is the ECU itself or the wiring.

Haven't found and wiring problems and the p28 shows no problems. Can you tell me what the smd value is on the circuit board FB5? I can fix this myself but need to know this. Also why did my other thread get deleted with this question

Even if you replace FB5 it is just a symptom of what has happened to the s300 and it still will not work.

Other thread was deleted because it was a duplicate of this thread.

Other thread was specifically about the FB5 smd that got deleted....hondata cannot disclose to me what the FB5 value is per the email I received. Also hondata informed it it will cost $300 to replace the board. Ill be damned if I'm going to be total out of pocket $800 for a piggyback. I WILL fix this myself and help anyone else who has any similar problem. Onto figuring this out myself since I am getting zero help from hondata. Should have just gone with a stand alone
