Harsh shifting on Toyota RAV automatic transmission and problem repair
If you own a 2001, 2002 or 2003 Toyota RAV4 vehicle and you are having problems with the automatic transmission, which symptoms are harsh shifting, loss of power, launching on second or third gear and/or hard engagement when it is put in reverse, then you should know that those problems are caused by a defective engine computer, which also controls the automatic transmission.
These problems are erratic and may only show at intermittent intervals or when the vehicle is warm or have been driven for a specific time. Sometimes it happens one day and the next morning it does not show.
When the computer (ecm or ecu) is defective, it will …read full article

Engine problems after touching the battery terminal with the ECM of my 1994 BMW 325i
This is something that happens more often than you may think. We have had customers that ordered a performance chip for their 1993, 1994 or 1995 BMW 325i/525i, and after installing the chip, they have accidentally touched the positive terminal of the car battery with the metal chassis of the ECM, which is a ground, and afterwards, the engine started having problems that will not go away even after replacing the ECM.
The key here is to ALWAYS disconnect the car battery before doing any electrical work. Mostly if working with the ECM, because the battery is in the path of the ECM’s way out. Either inserting or pulling the ECM to or from its bay, there will be a hazard of touching the terminals of the battery with it.
If this has happened to you and your car is having problems with the engine, …read full article
How do I know if my 2001-2003 Toyota RAV4 has immobilizer?
The immobilizer, which is an automotive security system integrated in many vehicles since 1996, is installed in some 2001, 2002 and 2003 Toyota RAV4 SUVs, but not in all of them and if it is present or not, that fact is not identifiable from the model number, or by its trim specifications, nor by looking at the VIN number and not even by looking at the ECM part number.
Working with Immobilizer software for virginizing files
To fulfill these requests, we will publish the basic immobilizer reset procedure by using external tools, not the included functions on each program, as many of them are undocumented or use custom hardware, not readily available for every user.
This procedure will also apply for the Toyota Virgin Dump collection, which is a group of files called dumps, as they were “dumped” out of the chip containing it, by using an EEPROM programmer to read such contents and not generated in any other way and also for the Toyota Corolla file and Toyota RAV4 File.

Interesting! – Loose parts in engine bay caused the vehicle to stall
Read here how a simple and dumb thing was causing a car to completely stall at intermittent times, with no apparent cause. This might be happening to your car…
For some time, we were wondering about the cause of an intermittent power loss on the car of one of our customers, that seemed to have no cure, as all the engine parts and electronics we checked tested ok.
As we made the tests, the problem was tracked down to possible problems with the ignition system, specifically suspecting of too low ignition timing advance. We went to that conclusion, as the reading with a scanner was …read full article
