Almost all Toyota RAV4  cars 2000-2004 year of production with 2 liter engines (1AZ-FE) and transmissions of the U140E - U240E series meet with the same problem, breakdown of the ECU (electronic control unit) of the engine and automatic transmission.

The output of the ECU is usually associated with the car's age and mileage, as over time micro cracks form in the soldering places, the contact of individual elements with the board is broken and the control unit loses the ability to correctly control the electromagnetic valves located in the hydraulic transmission unit and are responsible for gear shifting.

For the driver, such a malfunction is manifested in problems with shifting gears - shocks / jolts or slippings occur during shifting, and computer diagnostics give the following errors:

  • P1760 - ST / SLT Circuit Solenoid Switch Malfunction
  • P0750 - Shift Solenoid "A" Malfunction
  • P0753 - Shift Solenoid "A" Malfunction
  • P0755 - Shift Solenoid "B" Malfunction
  • P0758 - Shift Solenoid "B" Malfunction

Errors can appear periodically or be indelible and clearly indicate a problem with the computer.

Control units not only with RAV4 are subject to such a malfunction, below is a list of the original PCM numbers that are more likely to be repaired:

89661–42650 89661–42810
89661–42651 89661–42811
89661–42652 89661–42820
89661–42653 89661–42821
89661–42660 89661–42880
89661–42661 89661–42890
89661–42662 8966142681
89661–42663 8966142762

There are several solutions to the problem; it is the purchase of a new or used ECU  or the regeneration of your ECU. We prefer the second option, since buying a new unit on an old car is not economically profitable, and buying a used block is a lottery.

The rebuild of the ECU consists in disassembling, diagnosing and soldering parts.

After removing the cover from the unit, the master examines the board using a microscope, special attention is paid to power switches, diodes and resistors.

 

Soldering

 

After soldering and assembling the master resets the adaptation, which means that it is enough to install the unit on the car and you can go!

The whole operation (including removal and installation of the unit) takes about 2.5 hours, so you can send us your ECU and we will repair it.
