I’m 3rd owner of 2003 Corvette 50th Anniversary Edition.Purchased March 2019 with 58k miles.Have driven 4k miles in 5 months.With engine “warm” while driving, I have received on 3 or 4 occasions multiple Errors on Instrument Panel.

Service Vehicle Soon
Service Active Handling
Reduced Engine Power
Service Traction System
Service Ride Control

Nearly every module when scrolling thru the DLC records a U1016

Chevrolet indicated that I may have just a “ground problem” due to corrosion. There are 9 ground points on the chassis, but also 3 or 4 “Star Ground Connectors” that I also intend to clean.

Questions. I’m also interested in possibly having my PCM and BCM modules servicedPCM because of U1016 error code;BCM because my car will NOT go into TPMS Training Mode and I believe TPMS is enabled/disabled in BCM..Looking for recommendation on whom to send to?Recommendations!!??!!

 

Welcome to the forum. I don't know of any companies that do what you want to do but have you search the internet yet?

 

I have been looking. Saw a uTube recommending East Coast Supercharging In NJ and another called LS Engine swap that I believe are able to investigate at least the PCM.
I’m currently removing PCM and cleaning the unit with ACF50 lubricant plus the connectors. Nearly all errors are U1016 from supporting modules.
I am hoping to reinstall PCM and test drive this next week. If errors continue, i’m either going to pursue the 2 companies mentioned above or take to Chevrolet dealership. I do not have access to a Tech2 scanner.

Thank you you for responding to my question. Any further recommendations would be appreciated. Bob

 

I have completed the PCM cleanup and reinstalled into the car. Initial test drive (30+ miles) was successful. No errors! An update to my earlier post...site is LTSWAP.com.

Glad that fixed it. Thanks for posting back as it may help others in the future.

 

This is a final update to my PCM question regarding the error codes I was receiving on my 2003 Corvette. As I stated earlier, I had cleaned the PCM with ACF50 lubricant per a recommendation of a friend who is an AP Mechanic. It has been a week since I posted what I had done to the PCM and now I have taken 5 separate trips covering freeway and back roads trying to re-create the error codes, but they have not reappeared at all. I've logged 200 miles and so I'm now convinced that what I did accomplished the correction I was looking for. Just wanted to pass on the solution in case other folks have similar issues.

 

My last update was September. Car was stored in garage over the winter, but have put an additional 200 miles on the car since Spring going on tour etc and last weekend, I finally checked the DIC and the car reported NO ERRORS!!! I can only attribute my success to the ACF50 lubricant. Just wanted to pass on my success story for others to consider. Bob

 

Thanks for the update. Could probably help someone in the future with a similar problem. Do you apply this lubricant to the connectors? And is this a commonly available lubricant?
