Harsh shifting on Toyota RAV automatic transmission and problem repair

Posted by (14) Comment

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

Update about servicing your RAV4 ECM

Posted by (3) Comment

It is been 3 years now, after we started offering a service for repairing the ECM of your 2001-2003 Toyota RAV4, which is presenting a very common problem worldwide, which makes the automatic transmission to shift erratically. The ECM suddenly gets unable to correctly control the automatic shifting operations in the vehicle’s transmission, which is done through solenoids, and it can produce an internal failure in the transmission if it is not corrected on time.

What models does this cover?

This covers all 2001, 2002 and 2003 automatic transmission Toyota RAV4 vehicles, equipped with the 2.0L 1AZ-FE and 1AZ-FSE engines, either 4×4 (All Wheel Drive – AWD) or 4×2 (Front Wheel Drive – FWD).

Is my rav4 a 4 wheel drive? Is my rav4 awd?

If you have no idea if your RAV4 is a 4×4 vehicle (also known as “All Wheel Drive” or “AWD” or “4 Wheel Drive”) or a 4×2 vehicle (also known as “Front Wheel Drive” or “FWD” or “2 Wheel Drive”), it is easy to identify by …read full article

Engine problems after touching the battery terminal with the ECM of my 1994-1995 BMW 325i

Posted by (0) Comment

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 (immo)?

Posted by (0) Comment

The immobilizer (a.k.a. immo), 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.
