This service is for the basic rebuild of your 1992-1996 Lexus SC400 or SC300 engine control unit (ECU) or engine control module (ECM). This Lexus ECU repair includes replacing bad components and board cleaning. We replace all of the capacitors inside and also repair any broken traces caused by old capacitor leakage. We rebuild using only the highest quality Japanese Nichicon, Panasonic, Chemi-con, and Rubycon low-ESR capacitors. We purchase our capacitors directly from USA authorized suppliers.

It is possible that an ECU cannot be repaired due to extensive damage or needing repairs that would exceed the repair price in labor time and effort. We do not fix Code 71 errors caused by an ECU fault. If either of these are the case with your unit, we can help you locate a refurbished replacement ECU or refund your purchase less the shipping it costs to send it back to you. If you choose to purchase a replacement ECU, we will also apply any repair service payment you already made towards the price of a replacement ECU.


We have actual test vehicles on site that we test your Lexus ECU in – see our picture above. Ask other companies if they actually plug your ECU into a vehicle to ensure it runs and functions the way it should. Anything less is a gamble and potential waste of time for you!

    My ECU was un-repairable but they were able to help me get a replacment and it worked like a charm. Will be doing business with again.
