2000 cadillac catera: traction control light..the check engine light

Resolved Question:

Hi, I have a 2000 Cadilla Catera. The traction control light and the check engine light are one, along with that, the speedomoter won't work while those lights are on... This problem also prevents the transmission from kicking into a higher gear on the drop of a dime... I was told by Cadillac that it's a major part of the computer that has to be replaced... he said it's one thing, but it affects all of those things... Do you know what that might be?

Expert:  John Hicks replied 5 years ago.
The part he is referring to is the TCM (transmission control module). It is the part that is responsible for ALL of those problems. Replace that and you are good to go.
Customer: replied 5 years ago.
so it's not the speed senor, it's the TCM?
Expert:  John Hicks replied 5 years ago.
No, its the TCM. The TCM controls the signal from the speed sensor and all of the other inputs and tells the transmission what to do, it also tells the speedometer how fast you are going.
Customer: replied 5 years ago.
so awesome, do you know maybe where i can find a deatailed diagram and maybe some instructions on how to get to and do this myself?
Customer: replied 5 years ago.
and maybe where to buy this? if i can get a used one? sorry for asking so much lol
Expert:  John Hicks replied 5 years ago.
CTS
Customer: replied 5 years ago.
that's not a picture of a 2000 catera engine... that must be either a 97/98/99 or an '01...
Expert:  John Hicks replied 5 years ago.
I just included a picture of where the TCM is located, its not the same year as yours but it is the same location. To remove it all you do is take out the 4 screws and unhook the electrical connector. Then put the new one in. It is very easy.
You can find a used one by calling LKQ auto parts. They offer a warranty on all of their parts. I dont have their number with me here but if you google them you will find their number.

p.s. wow that was a fast reply. I was sending this message right as you typed your reply.
Customer: replied 5 years ago.
omg so it's not under the engine or anything? it's just right inside the hood? how easy is that?!?!?!?!?! and do you know about how much the part costs?
Expert:  John Hicks replied 5 years ago.
New they are around $380 so used would be in the area of 150 or so.
Customer: replied 5 years ago.
awesome, thank you so much! one more thing then i'll accept lol do you know if the part is universal for 99 and the 2000 catera... i found a used one from a '99 catera and it's only $60... is it universal?
Expert:  John Hicks replied 5 years ago.
They are not "universal" but if the 99 has the same engine that you have then Yes it will work. My database says 1998-2000 will all work as long as the motors are the same.
Customer: replied 5 years ago.
part says it was pulled from a wrecked vehicle... so i'm not sure and they don't know what engine it had... from what i recall, the 99 and 2000 have the same engine... think so?
Expert:  John Hicks replied 5 years ago.
I was just checking on that and you are correct, they have the same engine.

Customer: replied 5 years ago.
so awesome, thank you so so so much! this is the part i just purchased, thank you again ;-) Jason

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=220379973724
Expert:  John Hicks replied 5 years ago.
That is the one you need. Great price. very good buy. Im glad I could help you.
Customer: replied 5 years ago.
thank you again ;-)
Customer: replied 5 years ago.
hey bud, i looked in the spot on the diagram, took the lid off and it's the air filter... so i guess it's not in the same place on the '99 and the '00... what to do?
Expert:  John Hicks replied 5 years ago.
I am pulling the diagram up right now. I will double check everything.
Customer: replied 5 years ago.
Expert:  John Hicks replied 5 years ago.
Ok I figured it out. Im sorry about that, I missed the asterick (gotta love those things) at the bottom of page in my repair manual. In 2000 they changed alot of things over. They have two mounting locations. one is under the hood (which we now know, does not apply to your car). The other location is inside the car on the passenger side floorboard behind the kick panel.

It is also easy to change.
It is on the passenger side under the kick panel (little plastic piece by your right foot when you sit in the seat)
Remove the kick panel
You will see two electical components. One is the TCM the other is a Relay.
The TCM is secured by 2 bolts (8mm)
Remove the bolts and then pull the TCM down
Unplug the electrical connectors.
Plug the new one in and reistall. It takes about 20 min.
Customer: replied 5 years ago.
also after i purchased the part, the seller said this: Unfortunately, it should not work correctly. If you check your trans control box, it will probably have an RZ code on it, and this unit may cause an issue.

Customer: replied 5 years ago.
that's awesome! thank you so much! i was so confused lol... now i'm just not sure if it's the right part lol
Expert:  John Hicks replied 5 years ago.
My interchange manual doesnt show any errors for the interchange. Double check the ebay listing and make sure that he offers a warranty on his TCM, just to be sure is isnt trying to sell you a bad tcm that he KNOWS doesnt work.
Customer: replied 5 years ago.
well his refund policy says that if you ordered the wrong part for your car, it's non refundable... but if the part doesn't work, then it's refundable... just found the part where you said it was... the part i found was kind of big... 2x6x8 around about-ish lol does that sound right?
Customer: replied 5 years ago.
and also, what tool do i need for these damn screws on the car? lol it's like a star shaped screw/allen wrench type of screw thingy lol how's my terminology? lol
Customer: replied 5 years ago.
is this the part? it's nothing like the one that i just bought :-(

Customer: replied 5 years ago.
here's a pic of the part i purchased
Customer: replied 5 years ago.
something tells me this is not correct, unless the actual part is inside this bod
Expert:  John Hicks replied 5 years ago.
When you remove the kick panel you will see a recess in the body of the car, thats where the part is located.
Customer: replied 5 years ago.
jesus, it's like behind the glove box... i've been trying to remove the glove box because it's vertical LOL can't reach the other nut to take it off and release it from the mount lol fun! have a diagram of how to remove the glove box? lol
Expert:  John Hicks replied 5 years ago.
Unfortunately, my diagram doesnt show the specifics of how to remove the glove box. It also doesnt have any pictures. All it says for removal is to depress the sides of the glove box and allow it drop completely open. Then remove the screws along the bottom trim panel of the glove box and remove from vehicle. For installation it say "installation is in reverse order" ......gotta love when they take the easy way out and put that.
Customer: replied 5 years ago.
<p>lordy lol i'm at a stand still... the good news is, it looks exactly like the part online</p><p> </p>
Expert:  John Hicks replied 5 years ago.
They are torque head bits. Im not sure what size they are but I do know that you can get a cmall set of the bits pretty cheap. I think I paid $3 at autozone for my set.
Customer: replied 5 years ago.
gotcha...

got the part out, it was pretty easy... it just dislodged... and was a bitch to get out of the spot, but it's out at least... will the car work if even the one that's bad is disconnected? lol or should i put it back in until the new one gets here lol
Expert:  John Hicks replied 5 years ago.
no, do not attempt to drive the vehicle with the TCM removed. You can just reconnect the electrical connector and drive it around with out it being botled down and just replace it when the new one gets there.
Customer: replied 5 years ago.
oh ok cool... i'll let you know what the new part does ;-)
Expert:  John Hicks replied 5 years ago.
I will be here. Talk to you soon.
Customer: replied 5 years ago.
the guy is going to have it to me by saturday (providing the postal service doesn't suck as they usually do lol)

jason
Expert:  John Hicks replied 5 years ago.
if he says saturday then you can plan on it being there monday or tuesday. lol
Customer: replied 5 years ago.
i hope not, leaving monday for a trip lol
Customer: replied 5 years ago.
so i got the part and it didn't work... do i just pop the old one off and pop the new one on? or do i need to reset something in the car for it to recognize the new computer?...
Expert:  John Hicks replied 5 years ago.
It does need to be reset. Im not at the shop right now, But I will be there this afternoon. I will send the process to you as soon as i get there.
Customer: replied 5 years ago.
did you find out how exactly i reset the computer? do i put the new part on, then do the reset process?

i think i read somewhere that i disconnect both battery cables, hold them together for 10 seconds, then the computer will reset, but i'm not sure if that's accurate...

what do you think?
Customer: replied 5 years ago.
hello?
