The overhaul approach we take will depend on the year model, as these DENSO made units for Lexus and Toyota experience entirely different types of failures according to the year range. The process is basically always going to be a combination of repairs to the copper traces that make up the map of the board and replacement parts addressing whatever damage and/or conditions are present in the ECU. For instance, an early 1990s model is far more likely to need repairs due to the electrolytic capacitors leaking a corrosive fluid onto the board. Whereas a post 2000 ECU will suffer from typical decay of the metals in the aging SMDs that are used all over the place on these things, and they need replaced.
Most of the time, we see these particular ECUs for shifting problems, knock sensor issues, misfires, and no start/no communication, among many other problems. There is a wide year range covered with this model vehicle, so the failures can be quite varied from one to another. Either way, we are very successful with these and have an excellent track record.An ECU sent in for repair will not need any programming upon installation, as none of the security or VIN coding related parts are changed. 89661 - 24230 89661 - 24231 89661 - 24240 89661 - 24350 89661 - 24360 89661 - 24370 89661 - 24410 89661 - 24451 89661 - 24480.
