Hello,

I need a little help. I recently imported a 2002 Honda Civic EP3 from Japan, the car starts but was having a few electrical issues. As I researched, I found the common issue among owners was the MICU:

• No key chime
• No dome light when door is open
• No working AC
• No intermittent wipers
• Parking brake light stays on all the time

Unfortunately, I'm not able to source an exact replacement MICU (Part# 38200-S5T-J12), they're discontinued and sold out. I was able to get a used MICU from a UK Civic EP3 Type R (the part # is different). The good news, the electrical problems all got fixed, but the bad news the car cranks and won't start.
I'm pretty sure my car does not have an immobilizer or factory alarm. When I swap the original MICU back, the car starts.

Does anyone have a solution? Is there an EEPROM or programming that I need to swap over from the original unit? to the donor unit?

A little help please and thank you!

if the original is AutoMatic and the donor MiCU is for a manual, then you will see your problem. IIRC there is a method which requires a board level mod to convert the donor.
I don't know it, but its out there.

 

Hello,

thanks for the reply. Both MICU units are from a manual vehicle, pretty much the same car except one is JDM the other is EU.

If you come across the mod, please let me know.

Thanks!
