Tip Will Not Shift From Park.

[airedale]

Hello,

Mine is a 1999 C-4 Tip with 84k on the clock.

Last summer while backing up my car I accidentally cracked and broke off a piece of the stock taillight. Felt it, then realized what I had done all at the same time. Just lucky I guess.

So, I checked the price of a new one, a used one, and the conversion to these LEDs. The LED conversion was/is about the same $$ as a used set or a new single. I hiked it up and purchased the replacement pair in smoked. They look stunning on my silver car. Tasteful, and not garish, more 'modern' too and just a little shinny as well. Still like the way they look.

But the install has given me fits and starts and I am ready to go back to the stock.

Presently, I have all lamps back to stock. The 3rd brake lights are even back to the red. and the LED taillights are on the bench.

I have no brake lights.

And the Tip will not shift from Park.

Can this all be related somehow with the immobilizer? Is it a coincidence? Did something in the shifter/key switch transmission shifter lock just happen to fail at the same time?

I have a button in my Volvo to override this and have used it to move she shifter independent of this lock. But the Porsche has no button for this problem. {At least I don't know about it yet.} Is there a simple way to eliminate this 'feature' from my car altogether??? I would do that.

Made the first mistake of connecting the little side marker lamp plugins and had to replace two side marker 7.5 amp fuses.

I have checked any/all related fuses in the footwell and can not find another blown fuse. May have to ohm check each individual fuse with my multimeter.

Biggest bug is the "will not shift from park" with engine running and left foot on the brake pedal.

When I jiggle the Tip shifter lever the PSM light and the ABS light will come on; with the engine running. Each go off with the engine and do not come back on when the engine is re-started.

I have disconnected the battery for about 5 minutes and had this same bug when it was re connected.

Any help would be appreciated.

Thank you.

If all fusses are OK, i would start with a brake light switch check/replacement, the switch will solve the three problems, PSM/ABS, brake lights and Tiptronic park lock.
