Hi guys,
I just bought a 93 Accord LX in excellent condition. The problem is the typical ECU and TCM issues. Code 43 on the ECU and D4 light blinking with a code of 1. I obtained both computers from a 1991 Accord EX and was wandering if they can be swapped?

Thanks in advance.

You can't swap an EX ecu for an LX. The LX and DX have the same ecu for the 90-93 accords.

The codes indicate a problem with the various components on the car. The TCU code 1 indicates a problem with the lockup solenoid A.

The ECU code 43 is for a bad O2 sensor or fuel supply system problem.

 

Thanks for the info PAhonda.
