Having trouble with your Lexus LS400 ECU?



The Lexus LS400 is a very popular vehicle,
spanning a wide range of year models.

   LS400 ECU Repair & Return Service $250. including return shipping  

The most popular '93 - '97 Lexus LS400 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.

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.
