Dodge Stealth

These early nineties Dodge Stealth ECUs, TCUs and ECS 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.
