S1 rb25det awd ecu

[wadedos]

I have an awd rb25det s1 stagea with a 23740 0V300 ECU.

The ecu unfortunately got really wet and would start but engine light was on, ran like shit, no consult connection could be made.

Got a 23740 0V3010 to replace it, engine starts and runs mint, like the previous one did without check engine light and consult connection can be made.

How ever with the new ecu i now have the 4wd light and abs light on dash. Have checked 4wd computer for flashing codes and though consult got nothing. 

Does anyone have any ideas, suggestions.

Thanks in advance.

If the ECU got really wet, make sure that the plug pins are clean and dry. You might also have accidentally pushed one or more of them back out of the plug when refitting the ECU, which sometimes happens when more force than finesse is used.

I presume you mean OV301 or OV310 both of which are different (slightly) from the OV300

The OV300 is by far the most common so maybe you can find another.

Or have you opened up your original ecu and tried to dry it out?

Otherwise you will have to compare your new ecu with the original pinout and use a meter etc to work out the differences.

Below pinout appears to be for a 2wd auto but may help you.
