Ignition switch does not work!?

[RSK]

Cayenne S '04, open door & milage lights up, warning in center says steering is faulty, insert ignition

key, turn to right, no light in gauges come on & it never says START MOTOR.

Ignition is not coming on!! Yet ignition switch feels normal. I have checked all fuses, all OK

Do these have ignition switch problems?

Is it a key less entry problem?

Thanks for looking

How old is your battery?

Have it tested - both for load and for specific gravity of each cell.

[RSK]

The battery is new, just replaced, could the old faulty battery have damaged some component?

[Loren]

Since the battery was just replaced (and it worked prior) I would double check the connections and cables.

Did you do this yourself or did a shop do it? If a shop did it then make them fix it.

[working4it]

I agree with Loren (as usual it seems) it sounds like the battery is bad or not correctly grounded/cables tightened.

[RSK]

I did it my self & I run a small shop outside Montreal, I think the owner had been running the CS with a bad battery for months, because he said lately he's been turning the key to the left and then the center display would say start engine.

He would then turn to the right & it would start, he's been doing this for weeks if not longer!!!

I removed the battery & it had just 8 volts/no load, installed new interstate battery & ignition switch feels normal, yet seams ignition switch does not work at all.

does something need to be reset? basic settings? or has damage been done?

Battery was carfuly installed using proper proceedures, I have checked fuses in engine compartment & side of dash, Am I missing others?

Thanks RSK

Hmm... Kessy may need to be re-programmed.

You will need a PIWIS to re-program Kessy. I think I have a TSB on that if you need it - but PIWIS is required as I recall.

Chances are the gateway has lost communication within the network. You'll need the Porsche scan tool to try and clear the code and restart the system. Do you also have a steering wheel/lock or any other faults showing in the display?

[RSK]

Steering fault is shown in center display after opening drivers door, I have a PST2 & Durametric but will not work because ignition can't be turned on!

Loren if you can find that TSB, is it possible with PST2 or just with a Piwis?

Thanks!

[Loren]

I'll send you a PM.

You can try a PST2 but I do not know if it has the Kessy stuff. I guess you can try a clear codes and see what happens.

[RSK]

But how will I turn on ignition??

I would like to give PST2 a try before sending it to the dealer.

[Loren]

Try it first in may still give you access - turn key to on - lights or no lights.

[RFM]

Piwis includes a special menu in which the ignition possition can be avoided to do some test in case of a faulty steering column for example, which is a possible cause of your problem also. That option is missing or not working well with a PST2, as far as i remember.

'04 cs, open drivers door, milage lights up, insert key in ignition & center display says steering faulty!!!, DTC plug under dash has power with key out!! as it should.

Durametric will not work with key turned to ignition on, it says to check cable! no K-wire power from ECU's?!!

fuse box in engine compartment, ECU fuses #9,10 & 11, no power ignition on or off, fuse #15 ECU & fuel pump has POWER with key out of ignition

Feels to me I have a bad relay or ignition switch,

How about disconnecting both batterys & connecting both battery cables together for 10 seconds(just cables under the drivers seat) could it be SOS (stuck on stupid?)

Thanks to all for looking!

[mudman2]

Does the car have 2 batteries ? if so which one did you replace ?

[RSK]

I replaced the battery under the drivers seat, I've tested the rear battery & it is good!

[RSK]

The worst part of this is, without being able to turn on the ignition,

I'm unable to move it!!!

How do you get the shifter into neutral with out ignition

Thanks!

I believe it explains how to do that in the owner's manual.

Have you tested the battery??

[RSK]

The plot thickens!!

Today the owner of CS has said he had forced the steering wheel after it would not start, I think in an attempt to straiten the front wheels for a tow truck!

Now with not to much presure a very loud ratchetting sound/clicking coming from the steering coluum when you turn the steering wheel!!!

Looks like it needs a steering coluum.

Anyone with an idea of how long this job would take? Any speical precautions?

[Loren]

Porsche book time says 2 hours (200 TU) without steering angle sensor re-calibration (15 minutes).

PIWIS = Porsche Integrated Workshop Information System (replaces the PST2) (from our online Glossary)

This is a Porsche specific tool that all dealers/OPC shops are required to have and many independent Porsche shops also have.

A typical scanner can only read and reset emissions related fault codes. A PIWIS can do that as well as detailed diagnostics and re-programming/updating of all control modules.

A typical scanner is under $100 - a PIWIS is leased from Porsche for about $18,000 per year (includes monthly updates).
