NG900/OG9-3 (1994-2002) ECU Removal Instructions

Before you begin, remove the battery

negative terminal.

The ECU for NG900 and OG9-3 (1994-2002)

Saabs is located behind the glove box in the

passenger footwell. All of the following

instructions and pictures are shown from a

9-3, so there may be some variance in the

models.

There is a plastic push rivet that needs to be

removed. Try not to break it. The best way

is to use a small tool to push the pin of the

rivet through. This will release the rivet and

then you can reset the pin prior to

reinstallation.

Pull the insulation strip from the car in the

area of the glove box.

Then locate and remove the screw under the

glove box. The one in the picture is a 10mm

hex head bolt.

For the next step, take note of the 5 plastic

screw caps.

For each one of the five screw caps, use a

small flat blade screwdriver and flip the cap

open. Treat these little plastic pieces

carefully for easy reinstallation later on.

Then use a Torx T25 driver to remove each

of the 5 torx screws.

There is one additional t25 torx srew to

remove that does not have a cap.

Now the glove box can be removed. To do

so, pull the whole assembly towards you.

You may have to clear a snag on the bottom

with the air ducting, but it should come out

with relative ease. Don’t force it. If it

doesn’t come out easy, it’s likely hung up on

something underneath.

Once the glove box is free, remove the box

light connection in the back. They just pull

right off. Your glove box is now free to

remove from the car.

Here we can see the ECU as it sits in the

passenger footwell. It is secured by one

screw, this one happens to be another torx

t25 screw.

Remove the screw securing the ECU then

slide the ECU down and out of it’s location.

Flip up the latch on the ECU connector and

remove it. The ECU is now free to remove

from the car.

Here is an example of the Immobilizer code

on your ECU. If you are not sending in your

ECU for upgrading, then you will need to

send a picture of this Immobilizer code in to

Brew City Boost.

The Immobilizer code and VIN is required to

remotely marry the ECU to your car. If

incorrectly entered it will not start.
