TCS codes & 1 PCM code issue...
01 C5 convertible, automatic, all options except mag ride control.
PCM 1652 HC
TCS C1281 H, C1287 H, C1288 H
I sent the abs module to a guy in GA and had him repair it.
The DTC is reading adj. susp not working, don't exceed 159, etc etc and it looks to me like the car thinks it has the F45 magnetic ride control and the car does not have that option. I took it to the local chevy dealer to get them to hook it up to a Tec 2 and clear all this out yesterday. The said they can't do anything since they can't get the Tec 2 to talk to the car b/c the abs module won't communicate back with the Tec 2.
Any ideas, suggestions?

What do they mean by "the abs module won't communicate with the Tech II"? It looks like you're getting DTC's, you're not getting a no comms error.
I'm not sure why you'd be getting the P1652 unless the F45 suspension RPO was mistakenly programmed into the BCM. You would need a Tech II to check that out.

You don't need a tech 2 to clear the DTC's; they can be cleared via the car's on-board scanner (which I'm assuming is what you used to pull the codes listed above? I not post up and I'll provide instructions for how to do so) you just hold the reset button down while viewing a code. Doing so will reset all of the codes within that module. If you haven't reset your TCS module codes since re installing the EBCTM after repair you should do so.

Yeah the technician at the dealer said the Tech 2 wouldn't communicate with the car b/c the abs module wasn't communicating, but after I left there my friend informed me that something wasn't right as I wasn't getting a "no comm" under the TCS category. He also agreed with what you said, as did the tech at the dealer, that someone at some point mistakenly programmed the bcm to think the car has F45 susp.
So I have no clue what to do at this point....

Yes I already cleared the codes, cranked the car up and immediately the codes came back, unless after I hit the reset button and clear them I'm supposed to do something else. Yes I did clear all the codes on the TCS screen after I reinstalled the piece after it was repaired.

If it's No Comms start by checking the wiring to the EBCTM; make sure it is tight and secure. There's a possibility that whomever repaired your EBCTM messed it up but start with the easy things first.

I'm confused... Are you currently seeing 3 DTC's under the TCS module as you stated in your OP or are you seeing No Comms?

It's throwing those 3 codes like I said in the first post. What I meant was that my friend that repaired the module and you both stated that it doesn't make sense that the tech said the module isnt communicating when I'm not getting a "no comm" message, its throwing the 3 codes which means its working right, or at least connected?
At this point I'd say there are four primary possibilities:
1. Something is wrong with you OBDII port (if the Tech II could communicate with other modules this is not a possibility)
2. The guy operating the Tech II didn't know what he was doing.
3. There is a wiring issue going to your EBCTM. Pull the connectors and inspect the male and female ends for damage (bent pins etc.) Make sure it is seated properly and locked in. Make sure that a wire hasn't come out of the back of the connector.
4. Whomever repaired your EBCTM damaged an internal component during the repair. Take it back and have them look it over/test it. What code(s) were you getting that made you send it out for repair? Was it the same three listed above?

sounds like you have a used PCM from a differently optioned vehicle compared to yours. You need to have the PCM flashed to your VIN....which clearly doesn't have F45. The dealer should be able to do it as long as you have not had any modifications to your stock tune....otherwise, find a good tuner..piece of cake for him.

The dealer reprogrammed the ebcm and ecm and yet I'm still getting an "active handling" display on the DTC and the two codes under TCS that I'm getting are 1287 & 1288
But at least all the other stuff is gone....

I think there is a misunderstanding about the messages you are describing. When you say 'getting an "active handling" display on the DTC' I think you mean you are getting the message on the DIC (not a DTC.) Is this message on at startup or does it come on when you are driving?
Your description of the current situation is easy to figure out. The 1287 and 1288 are likely caused by a bad SWPS (steering wheel position sensor.) Those codes will then trigger the 'active handling' message you are getting on the DIC.

I called the dealer and my cost on the SWPS is like $80 or less, I guess I might as well get it since they have it in stock, install it, clear the codes and hopefully it will all be fixed.

Sorry about the confusion. Upon start-up and initial take off, no codes and "no active handling" light comes on, but once you drive it for a couple minutes and or pick up some speed, the "active handling" &"service vehicle soon" display comes on, and the trac control light comes on and stays on. I have tried clearing the code while driving on a long straight rode to try and see if the car would "re-learn" itself so to speak and no luck there. I did have a 4 wheel alignment performed so I know the car and steering wheel are all straight.

Not that hard of install. You gotta take the steering wheel out.
There is a thread on here that is very detailed with lots pics of install.

Yeah maybe $80 was list and my cost sixty something, I don't remember. Yeah I found a very detailed thread on how to take everything apart to install the new sensor but I've been slammed at work and don't have time to do it so I just took it to the dealer. I will let you guys know how it all pans out.
thanks for all your help

Well $438 later the car is fixed. They charged me full list on the part and apparently full list on the labor, everyone was gone except the cashier when I got there at 5:30 so I have to go back and talk to someone today about the money part, but the plus side is the car is fixed. Next time I might just bite the bullet and try and install the thing myself.....I was thinking a bill in the mid 2s, not 400 something...

Is all they did replace the SWPS? Did they give you a breakout of parts vs labor on the cost?
