UK 99 C5 Manual resto project

[Llewelyn]

Hi guys!

I've just purchased a nice torch red C5 99 manual car as a non runner and I'm doing a YT series documenting my progress. I may need some assistance at some point. I have owned a C5 manual previously ("TE51CLE") so have some familiarity but I'm certainly no expert!

Take a look and if you like it I'd appreciate a "like" or subscribe Part 1 and Part 2 are live on YouTube! Thanks!

If you can offer any help or advice on what you see I'm listening, just drop us a comment either here or on YT.

Link to videos is here:

I've been a forum member for a while actually so I've deleted the "new member" bit!

It only costs £40 to join the club then you're not pissing paid up members off when you advertise or post links.

Thanks for the warm welcome sir

Blimey, I was considering buying that one a while back (when it was running)! Good luck with the project – I look forward to seeing how it progresses!

The seller was a really nice bloke and the car was sold in good faith - The fault will most likely be down to lack of use, it seems like it's been really well looked after generally. I am very happy with it given the price paid. Thanks for taking an interest, I would imagine you'll be quite fascinated since you were considering buying it!

It's always good to see an optimist in action!

Don't forget to join the club.

Ha! Yep that's me! Can't be anything too difficult to sort I'm sure

Joking aside I genuinely think it'll be okay. I'm fairly handy with mechanics and electrics and the C5 seems pretty basic compared to some stuff I've worked on. Also I've got the physical shop manuals and online support/info seems pretty good as well.

Hi, the club rules explicitly forbid non-club members posting adverts and whilst this is not strictly an advert but you plan to promote your YouTube channel, which can arguably benefit members, perhaps you might want to join the club and get the added benefits it offers. This website does cost the club money to run and if you are planning to used it resources it only seems fair to contribute to the club. I’m not wanting to be unwelcoming but just point out the reality of running the club. Enjoy your C5 and there are many club members willing to help you with any issues

Thanks - Feel free to delete my post, I am not trying to self promote, I simply thought fellow Corvette owners would like to see a bit of UK Corvette action on YouTube. Sorry if I misunderstood the rules and if I’ve upset anyone. I may join the club in the future but right now I feel like I’m being railroaded into it both on here and on Facebook which makes me naturally resistive. It doesn’t feel very welcoming if I’m honest.

 

[Vettemike09]

Hi, we are not trying to railroad you but you have to understand that websites and Facebook groups have a cost to run, actual cash as well as people’s time to moderate and manage. This is done by club members for the benefit of club members. The committee took the decision to keep these forums open rather than make them closed as they are good sources of new members who are looking for help either to buy or restore a car and even ahead of actually finding a car. We do allow people to join them but with restrictions which they have to agree to. There are areas that are only available to club members. For example, discount codes to events like the upcoming London classic car show. Many members find that being a club member gets them an insurance discount, often equal to or greater than the annual fee. So I guess what I am saying is it is only fair that you join if you want to use the resources to post video etc rather than just watch from the sidelines like most non-members do.

Hi.
If you need any help with insurance at all then please feel free to drop me a line.

Part 3 now on Youtube

 

[Pitre]

For members reference, the committee has discussed Llewelyn's status (he's not currently a CCCUK member but we're hoping he will join soon!) but we agreed that it was in the interests of the wider CCCUK membership to be able to easily link to his videos which show the efforts he's currently going to to get his C5 up and running and are publicly available via YouTube. As Llewelyn isn't actually promoting his business or making money out of self-promotion we hope that you will find these videos interesting and publishing the links to YouTube do not contravene our current rules.

Part 3 now on Youtube

Seems like the blind leading the blind

You're screwing yourself over
as you're NOT to be opening and closing the doors while in the 30 minute PCM to BCM security relearn
Zero, causing other controllers to wake up and also drawing more voltage, you do not want the other controllers talking on the
on-board Startbus network as that is stealing time away for the PCM and BCM to use that network to resync and pass the security code

Opening door and if VATs relearn is correct, then the security light flashes, if hard on than relearn was not done correctly

This relearns process GM did was to slow down those trying to steal the car so the relearn times have to be exact and why best is to use a stop watch for the 3 cycles of 10 min on and 5 seconds off

When process is correct towards the last cycle, the DIC should show like a P1631 error code (DTC)

If so after the last learn cycle is key off then back on, that DTC must then be cleared before a start either via the diag mode or DIC,
code reader, or OBD-II scanner

IF opening drivers door the security light is still not flashing than, better go back and do this relearn process again as VATS prevents
fuel system from being functional

If engine does not run well once starting to drive it
Possible you also need to do a crank position sensor relearn due to using a different PCM

Would make this easier for those watching video, on not getting bored watching people take a wheel off or people playing music\
Keep to the point of what you're trying to show the viewer if wanting their help

Thanks - Very helpful! I am not an expert, just an enthusiast having a mess around with an old car. I really appreciate the advice.

The videos are more of a log of my progress for entertainment purposes (my own entertainment mainly), they're not meant to instruct or teach anything so apologies if you find the pratting around irritating!

From what you are saying then it looks like the VATS relearn process was unsuccessful in which case I need to follow the same steps but not open any doors?

 

[teamzr1]

If you think about it, that VATS and security system are from the same controller
So you're trying to do the VATS relearn and at the same time you're opening and closing the doors during the process, which interferes with the relearn process
As I mentioned, GM made this relearn process strict so to make it harder if someone is trying to steal the car by doing this process

Again when the door is opened that is what signals that controller and commands the light on dash to flash, if all is well
and hard on if something with VATS is wrong

There is a security seed code, both the PCM and BCM have to have sync'd that code up and agree they are the same, if not then it is commanded no fuel system functional to prevent starting and stealing the car

As mentioned also you do not want to wake up all other controllers to be yacking on the Starbus network so MUST not have anything else turned on like radio, lights, doors, etc

How this works

Programming Theft Deterrent System Components

Important:

• The body control module (BCM) must be programmed with the proper RPO configurations before performing learn procedures.
Refer to Body Control Module (BCM) Programming/RPO Configuration .

• If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn the passkey data code immediately. The existing PCM however, must learn the new fuel continue password when the BCM is replaced.

• If replacing a PCM with a GM Service Parts Operations (SPO) replacement part, after programming,
these modules will learn the incoming fuel continue password immediately upon receipt of a password message.

Once a password security seed message is received, and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password and will require a learn procedure after programming to learn the current vehicle's password.

Conditions
Use these procedures after replacing either controllers :

• BCM
• PCM

10 Minute Learn Procedure with Tech 2 or without further below)
Tools Required
• Tech 2
• Techline terminal with current SPS (Service Programming System) software

Connect the Tech 2 to the vehicle.
Select "Request Information" under "Service Programming".
Disconnect the Tech 2 from the vehicle and connect it to a Techline terminal.
On the Techline terminal, select "Theft Module Re-Learn" under "Service Programming".
Disconnect the Tech 2 from the Techline terminal and connect it to the vehicle.
Turn ON the ignition, with the engine OFF.
Select "VTD Re-Learn" under "Service Programming".
Attempt to start the engine, then release the key to ON (vehicle will not start).
Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF (the vehicle is now ready to relearn the password on the next ignition switch transition from OFF to CRANK).
Turn OFF the ignition, and wait 5 seconds.
Start the engine (the vehicle has now learned the password).
With the Tech 2 (scan tool), clear any DTCs.

30 Minute Learn Procedure ( can be done without the Tech-II)
I use a stop watch as times have to be exact and stay in the car, doors closed

1. Turn ON the ignition, with the engine OFF, doors closed and all other electronics off
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds.

5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes
(the vehicle is now ready to relearn the password on the next ignition switch transition from OFF to CRANK).

Important:

The vehicle learns the password on the next ignition switch transition from OFF to CRANK.
You must turn the ignition OFF before attempting to start the vehicle.

Start the engine (the vehicle has now learned the password).
With a scan tool, clear any DTCs

If after doing this and open door, if the security light is NOT flashing than the process was not completed
and PCM will not command the fuel system to prevent stealing the car

As a former C5 owner I enjoyed the videos and I don't mind a bit of banter thrown in. Do listen to Team though as he knows what's what
