Steering Wheel Buttons 98 STS

[akaz87]

I have a 1998 STS Seville. There is a factory phone built into the car with buttons from the phone built into the steering wheel in place of the normal temp buttons. I was wondering how hard it would be to change these phone buttons to the normal temp buttons. I dont use the phone so it would be nice to use the temp buttons.

i am very interested in this as well, because I need to install the delco phone kit (purchased on Ebay) into my 98 eldo.

And also, are the buttons for the Fan and Temp(?) to replace the phone buttons even available?

Where did you find the kit? I was looking for one too. I have all the parts, just missing the headset. I am put the phone in instead if we can't find something else to do with the steering wheel buttons.

You can install the temp buttons, but you're going to have to find a way to get them to work the HVAC system. It may have totally different wiring or it may have to be programmed by the dealer with a Tech2 to get it to work.

ok there is a way to re-program the PCM just do a thread search for "steering wheel controls" or search "phone" there are lots of posts on this subject and it will give you detailed instructions how to do it.

T A OUT!

I'm not sure about the 98+ Seville. But it is in the override section of the instrument panel cluster, in your FSM. I have the phone installed --it has Onstar buttons and since I have been told I can't use it without ONstar, I disabled it by telling it the phone was not installed. They automatically defaulted to HVAC controls (but the buttons have phone labels instead of fan and temperature).

I'd be interested to see if cas2 gets a carrier to support it, I'd like to use it since it has hands-free built in.

That is really good info, mtflight. Would it be possible to jot down the procedure and button sequence for disabling (and then re-enabling) the phone?

This would be awesome, I have a 98 Concours, but I would imagine the sequence would be similar. I read up and searched, all I found was IPC override, Option E. Is that all we need to do?

TY in advance

Find the instructions attached. Follow at your own risk.

Cheers!

mtflight, this is helpful and I thank you. From what I see, I need to change Option C from celular phone installed -- 16, that part I got. What do i change it too?

I didn't see an entertainment section...

IPD05

This code displays the value (A/D count) of the steering wheel control switches at the IPC connector C2 terminal B11. Refer to Entertainment Section in order to determine which one of the 8 functions is requested. The value may range from 0-255.

TY

If you don't want the car to know the phone is installed, you would subtract 16 from the total on that option.

If you installed it but your car does not know it's there, you would add 16 to Option C count.

You have to be very careful, not to change it to say 17 instead of 16, or you would lose your IPC and need to get a new one.

I got it, and it works perfect, so cool! The Temp control and fan control work perfectly, right from the wheel.

Now, using that same logic, I changed Option E to 127 and then to 111. It was at 43, +64 for coolant temp, + 16 for tach, + 4 for mph. At 127, I got everything (including the MPH on the DIC) except the tach. My understanding is the tachometer (digital) doesn't work on my year. Oh well...

So, it is now at 111. I didn't see anything smoking and the car started again with no codes, so is it safe to say I didn't fry my IPC? I did everything by the book.

Will be nice to have digital MPH, I miss that from my 94 Concours.

TY again

Glad it helped you!

cheers.

MTFLIGHT can I also get those instructions! I need to change my phone controlls to HVAC controlls. THANKS!

[bill98sts]

I need to reprogram my steering wheeel phone controls to HVAC controls, My car used to have the phone but I took it out and replaced the phone buttons with the HVAC buttons. they still try to access the phone though. I cant find the IPC Override info anywhere on this forum. please help. If not what is the FSM book and where can I purchase one? Thank You!

Not sure if you can do what you want to do.

FSM = Factory Service Manual. Check Ebay or http://www.helminc.com
