This item is a rebuilt 2000 Lexus LS400 ECU part number 89661-50531. This Lexus ECU includes new capacitors, board cleaning, and damaged or compromised component replacement. We rebuild using only the highest quality Japanese Nichicon, Panasonic, Chemi-con, and Rubycon low-ESR capacitors. We purchase our capacitors directly from USA suppliers.

Typically 1998-2000 Lexus LS400 ECU’s do not need or get their capacitors replaced because they are a revised style not prone to leaking like the 1992-1996 ECU’s. Since we already have the ECU we will sometimes change the capacitors anyways as a preventative measure. If the unit part number ends in -84 that means Denso already rebuilt it so we don’t change out the capacitors.

1998-2000 ECU’s have the vehicle immobilizer built into the ECU. We will virginize the ECU, or delete all existing keys, for you so you can program your original keys into it. You will need up to three keys to do this. What this means is that the ECU will be in a blank state ready to accept your keys.  There is a process to do this by putting your keys in one by one into the ignition switch. We will include directions with the ECU. This procedure must be followed exactly otherwise key programming will fail.  This is a free service we provide otherwise you would need a locksmith to complete the immobilizer programming.

Brackets are NOT always included. Sometimes we receive cores back without brackets. Please remove and re-use your original brackets if you receive an ECU with one or both brackets. Sending an ECU back without brackets as a core will not affect core value. Brackets are not available from the dealer anymore.

Interchange part numbers: 89661-50530, 89661-50531

Immobilizer reset sequence:

  1. Install the ECU
  2. Insert any key into ignition lock cylinder and remove it immediately. The security light should illuminate and remain on
  3. Insert the first key into the ignition lock cylinder, but do not turn it on. The security light may blink indicating the key has been accepted.
  4. Wait 5 seconds then remove the first key. Security light should remain on.
  5. Insert the second key into the ignition lock cylinder, but do not turn it on. The security light may blink same as step 3.
  6. Repeat step 4.
  7. For the third key repeat steps 2-4. Wait 30 seconds for programming mode to close.
  8. If you do not have a third key: You will need to manually close the programming mode. If you want to only program one or two keys, once you remove the final key the security light will still be illuminated. Press the brake pedal 5 times or turn the ignition on to off and back on again 5 times. This will end the key programming sequence. The car should start and run with your one or two programmed keys.

To test, insert a master key and the security light should stop blinking immediately. If you insert the third valet key, the light will remain solid for two seconds and then turn off.

If the car still does not start you may need to re-sync the ECU and the immobilizer. Perform these steps.
1) Insert a master key into the ignition and turn to “ON”. Do not start the car.
2) Use a jumper wire and connect terminal 3 and 14 on the OBD2 port for 30 minutes.
3) Remove the key from the ignition, remove the jumper wire, and attempt to start the car.
