  1. Saab 9-3 Ignition Switch Module (ISM) Replacement, The starting point: passo 1, imagem 1 %32
    • Our starting point: The center console with the ignition switch in the middle

    If this is bad does the clocking ignition switch have to be replace with it as well. My 2003 SAAB is not starting and the lights and gauges stopped working and were flashing. It also would not shift..Is this really caused from the ISM?

    • Underneath the air vent controlling air flow to the passengers from the center console sits a square duct.

  25. Saab 9-3 Ignition Switch Module (ISM) Replacement: passo 25, imagem 1 %32
    • The Haynes manual suggests pulling this out next, and although it is possible to do so, it requires force, and is much easier to do later when all other fixings have been removed.

  26. Saab 9-3 Ignition Switch Module (ISM) Replacement, Cable bundles: passo 26, imagem 1 %32
    • There are two cable bundles connected to the center console from the rest of the car. One is connected via a large, square plug with a red tab.

    • Push a screwdriver inside the red tab and pull, and the connector splits neatly apart.

    Would you happen to know which of those wires sends the voltage when cranked? I know the violet/yellow one provides voltage when key is turned to ‘on’. I’m trying to install a push button starts. Thanks!

    • You now have the ISM in your hand. Swap this with a replacement unit. Mine cost £126,00 new from eBay. Clip it in the same spot, and connect the cable again.

    Did you go for a genuine ISM? How is it holding up today?

    • The rest of the procedure is doing the dismantling in reverse. However, this is the best order that I found (choosing the wrong order once or twice):

  36. Saab 9-3 Ignition Switch Module (ISM) Replacement: passo 37, imagem 1 %32
    • The square air conditioning duct goes in first. The console goes in next. It is a bit awkward to riggle past all the lugs, screws, tabs and cables, but just persevere. Once in, fit all the screws holding it in place, including the awkward ones.

    • Connect the two cables. The earth connector is push-on, and the square plug self-locks when the red tab is pushed.

    This is a good time to test out your new switch if you haven’t already.

    • Next, fit the retaining frame underneath the gear lever, all screws around it, then the shiny gear lever surround trim, and finally the rubber mat in front of it. Fit the side rear panels, then the front panels (fasten them with the single screw), then the rear cover.

  38. Saab 9-3 Ignition Switch Module (ISM) Replacement: passo 40, imagem 1 %32
    • With all side panels in place, re-fit the screws around the gear lever and CD holder. Finally, slide the handbrake cover in place, and screw the CD holder in. All rubber mats put in place (you *did* clean them whilst you had the chance, right..?). You are done!

    • Touch Wood, my car is now purring, with none of the issues I had before. Having heard quotes from around £1,000 upwards for a complete ISM / CIM refit, I am well pleased with the result.

    I have not as yet got the replacement part but, I'm not saying that it'll be the easiest set of instructions to follow. It looks like it's not going to be the hardest either, thank you.

    Just completed fitting ism … driving the car for a couple of days to make sure issues resolved before putting the rest of Humpty Dumpty back together again

    thanks very much for posting this, was quite satisfying to do, saved a fortune

And the key worked once plugged in and the battery is reconnected?

Michael Sullivan - Responder

These are great instructions. I had the dreaded ‘steering lock malfunction’ warning message on my 9-3. Bought an ISM off eBay for £35 and had it fitted and working fine in 2 hours. Thanks so much for posting.

Mike - Responder

Instructuctions spot on. In 1.5hrs I had the ISM out, cleaned and back in. And no more steering lock errors. !!!

Does anyone have advice on how to replace the ignition switch on a 1998 9.3 automatic transmission Saab

davina gammon - Responder

Most of these steps are not necessary at all, you can pull the ISM out from the side when you have removed the side panel, its tight but more than possible. This is very easy, 3h is a joke it takes 30 minutes at most!

Filip Andersson - Responder

My starting point was a Haynes manual. Not all the steps worked as described. The steps above will work. Three hours it took, and it didn’t feel like a joke. By the way, the Saab is still chugging along nicely (touch wood). Not missed a beat since the repair.

Glad you’ve found an easier way. For the rest of the mere mortals, me included, the above steps will work.

Lars Erlandsen -

Any clue as to why after install of new switch the key won't turn?

Ryan Nordbrock -

Does it need coding into car or is it just plug and go

Jason platten - Responder

The steering wheel unit will need re-programming. However, the ignition switch that I replaced, listed above, needs no re-programming at all!

Lars Erlandsen -

Great instructions. I also had the ‘steering lock malfunction’ warning message on my 2011 soft top 9-3. Fixed by replacing the ISM with a used item from eBay for £38. If only Haynes instructions were this good!

Très bon tutoriel changement en 1H30 .

Merci beaucoup Lars

vous êtes les bienvenus (Google translation from “you are welcome”) :-)

Lars Erlandsen -

Thanks for this advice - it’s really well produced. However I can also vouch for the alternative method which just involves removing the side panels and carefully lowering the ISM out of the left hand side. In total the job took about 20-30 mins and the car is good as new now. I also removed the gear lever surround to give it a good clean. But still thank you as I did follow a few of your steps.

Jeff Hilton - Responder

Thanks great photos and information is ism plug and play or needs re programming thanks Clive

Clive Briggs - Responder

Hi, Clive.

The ignition switch in the center console is plug and play. The unit that is wrapped around the steering wheel, however, needs re-programming. I was warned this would involve a 4 figure sum of money, so I was happy my £120 key switch gamble replacement did the trick. And the Saab is still running. With the key switch working flawlessly…

Lars Erlandsen -

Thanks for the tips. I solved the same problem at the service station. But I installed the timing light for MSD ignition myself using your instructions.

William Clark - Responder

Do i need to code/program it after replacement? What about keys, do they need to be coded again?

Robert Rupa - Responder

Just read your instructions and followed them to the letter , many thanks

Julian Barnes - Responder

Hello, do you know if a Tech2 reprogrammation is needed once ISM has been changed? Is it part of security components of the car?

Famille Ponal - Responder

and is OBD fault “B3057 ox48” linked to ISM module issue?

Famille Ponal - Responder

Hi.

As I said in my tutorial, replacing the key module does not require any re-programming. If you replace the full security module around the steering wheel, it will need all re-programming…

Thanks,

Lars Erlandsen.

The NIST frameworks were designed as flexible, voluntary frameworks. The fact that they are flexible makes it relatively easy to implement them in conjunction with ISO 27001.


This is largely due to both standards having a number of common principles, including; requiring senior management support, a continual improvement process, and a risk-based approach.

I have a question. What issues were you having that made you replace it. I’m getting the steering wheel lock message and sometimes the car won’t start. I have to take the key out and put it back in and try again to start it. Also I don’t hear the steering wheel unit unlocking everytime like it used too. It says steering wheel locked but it’s not actually physically locked. I’m hoping it just needs a new ism.

Twinturbobmw 535xi - Responder

For reference, this is exactly the scenario that I faced, and that made me replace the unit in the first place (and write the tutorial).

I cant turn the key in my ignotion [2006 9-3 auto wagon runs sweet as a bell] . when I put the key in the ignotion the needles on the instrument panel dance/vibrate? ! Its liek the key has forgotten it belongs to the car Again. [this happened a few weeks ago, but it was with my mechanic and he simply re-programmed the key].
