Overhead Console Circuit Board Fix

There is a thread on repair of the overhead console circuit board. I can't find that thread now but, it was extremely well done with instructions and pictures. This has been an endemic problem Toyota has never admitted to. Their circuit board manufacturer (Mexico?) has had a quality control problem for years. Been there, seen it as electrical engineering project manager buying circuit boards made in Mexico.


That Toyota ignores this problem and not dealt with the quality control of sourced parts is unforgivable.



If yours is the same circuit board I had to repair, there are two surface mount resistors that had "cold solder" joints and, for many, dislodged. The resistors are marked "510". Following the thread and pictures, I was able to remove the circuit board, then the resistors using "d-soldering braid", good flux to clean the contacts, a fine tipped soldering iron and fine tipped needle nose pliers to hold the resistors in place while re-soldering them. Having had the right tools and supplies, the problem was cured and never occurred again.


If you have, or can find some one with reasonably good soldering skills, the repair task is relatively easy. It takes more time to remove and re-insert the circuit board in the vehicle than it does to fix the cold solder joints. A local, competent tech should cost you much less than an $800 replacement circuit board that may have the same problems.



Good luck
