Having trouble with your Lexus ES300 ECU?

The 1992 - '96 Lexus ES300 ECUs are prone to
failure due to the original factory electrolytic capacitors.
When they get to a certain age the capacitors start slowly
leaking an oily fluid that eventually will corrode the copper lines
of the printed circuit board, as well as degrade or ruin the metals of any components that were saturated in the acidic chemical.

After an ECU has been properly overhauled,
the capacitor problem will not be back again.
Only the old original factory capacitors,
be it from Nichicon, Rubicon or otherwise,
are what is causing all the trouble.
These capacitors were all made in the 1980s, and
later wound up in various Japanese brand electronics
and automotive control units in the early to mid 90s.
This is not a problem with contemporary components.

Later models after around 1998 and up, with have other issues, not leaking capacitors. We are able to restore full function in these as well, and the repaired unit will not need reprogramming at re-installation.

We usually only keep it one or two business days,
depending on time of arrival and the amount of time and
attention any particular ECU is going to require.
The damage on these can vary quite a bit, so it's all about
what we have to work with when we open it up.

Send your ES300 ECU to us at the address below,
please tape a note to it with your name & phone #,
include a brief description of your symptoms.
After it arrives we will inspect it and call you to notify you.

No reprogramming is needed when re installing your ECU

We charge $35. for inspection plus return shipping cost
(but only if there is no sale or repair)
