I replaced the MCU in my 2002 civic. Now the car is a no crank/no start. It clicks, but the starter will not turn at all. Prior to installing the MCU I had the common symptoms. No door chime, no low wiper setting, power doors/keyfob not functioning, a/c inoperable. All of those issues are resolved, but the car will not turn over.
The part number that I bought was a 38200 5sp a31 p3. It replaced a 38200 5sp a31 c1.
