Well. I Finally got my single trubo on and went out for a test drive.I got the car out of the shop and after warming it up I went to pull out and it stalls.The car idles fine,you can rev it in neutral and it holds an idle in gear.But as soon as you pull forward the car goes about 4' and stalls everytime.I turned off the traction control and applied the brake to see if it would take any load.I brought the revs up and as soon as the rear tires started to spin it stalled.All I did was install the turbo and add race fuel.Nothing else.The battery died during the winter and I had it out a couple of times for the install.Oh.I also added a GN air temp senser to the front of the intake and new plugs.This car is all stock.85,000 miles.Ran great before except it did the same thing once before in a parking lot.I waited 30 minutes and drove away.
Anyone have any ideas?
Thanks.

 

Are there any messages on the DIC ????? Sounds like the fuel cut-off for the column lock problem ..... it is killing the engine when you get to 2 MPH.

What DTC codes are set ?????

 

Yep!!! Do you see a PULL KEY WAIT 10 SEC message? Check the DTCs

BC

 

"Messages are pull key wait 10 seconds" and "service column lock."
What is a DTC code?No serves engine light.
Thanks.

 

Yes.How do I check the DTCs?
Thanks.

 

It helps a whole lot if you list the symptoms such as DIC messages ... they are there for a reason ....

To display the DTC data .... go here for instructions .....

https://www.corvetteforum.com/techti...D=26&TopicID=1

BE CERTAIN to list the ENTIRE DTC. They look something like P 1234 H .... we need the first letter (P says it is a Powertrain issue ... B is body ... etc.) the next four numbers are the code (and that's why we need the leading letter because both the Powertrain and the Chassis may have a 1234 code ..... and the last character will be a C (Current) or H (History) showing the status of the code.

Easiest to wait for the DIC display to cycle through to MANUAL MODE, then write the codes down and post .... leave out the codes starting with a "U" as they won't be part of this problem.

 

Great .Thanks.I'll check it out tomorrow.I forgot to say that I left the oil temp senser off the car as I used that port for my turbo feed.Not sure if that affects anything.
Take care.

 

OK.Here is what I found.
10 PCM
P0530HC

28 TCS
C1255H

60 IPC
B1543H

A1 RDCM
B2283H
B2285H

A0 LPCM
B2252H
B2284H

AS SCM
B0851H
B2860HC

Thanks again.

 

Sounds like you put in after market seats into your car and removed the SCM (Seat Control Module).

This may be your problem, it seems some vettes will not run right without the seat controller, My 2002 Z06 would not run without the drivers SCM plugged in.

If you run to run the aftermarket seats, you'll need to pull the seat controller and harness from your old seat and plug it in.

I would try this first.

 

OK.It has stock seats.Some of the wiring to the seats has been unplugged from the harness.The memory has always acted up.Problem is that I did nothing with the seats after I put the car away last year in the fall.It was running perfect and had just completed a 1500 mile trip.The stalling seems to have started over the winter while I was installing the turbo.
Thanks

 

Your active codes are for the seat controller and your A/C system.

Telescopic and Memory areas and missing SCM. I am assuming you have either a vert or coupe.

I would look into repairing this as this could be tha cause of your problem and it's the only codes that it is throwing.

I would clear your codes and see what codes come back. Electrical problems are sometimes tough to figure out.

 

The car is a coupe.I did disconect the A/C lines to clear for the turbo.I'm going to make new ones later.I just want to hear some rubber after this long winter.How do you clear codes?Thanks

 

OK, none of these are related to your column lock issue.

Do you know if the Column Lock recall (4006c) has been performed on the vehicle ??? Is the car an automatic or a manual transmission vehicle ???? Is the column "locked" right now (steering wheel cannot turn) ??? I'm going to assume it does not have a 3rd party "Column Lock Bypass" installed.

Finally, when you turn the key to ON (not START) can you hear any noise from the steering column ??

If your battery is even SLIGHTLY below full charge. the column lock error can occur. First thing I'd try is jumping your battery to a battery on a RUNNING vehicle (ensuring a good voltage level) then on your car insert key ... wait a few second ..... turn key to the ON position .... wait a few seconds (and observe DIC messages) .... then turn key to START if no DIC error messages in the ON position.

Let us know if that starts the car .....

 

Not sure what year codes you're looking at B2860 is telescopic wheel.

That's why I thought he had aftermarket seats (i.e. SCM) error.

 

Read posts #1 and #4 ..... the OP is complaining of a column lock error. He has other issues such as the B2860, which I listed in bold in post #13 as "Steering Column Position Sensor voltage out of range" ... which is a telescopic wheel problem.

The car has a number of issues (EBCM shows a C1255 ... ) but the column lock appears to be the most pressing, let's try and get that one cleared first.

 

Yeah, I only read where he posted the codes and missed that part.

Time for a CLB. Had the same problem with my bro's FRC and had dealer do latest fix of removing steering column locking plate and reflash of PCM.

 

I have a hunch this may be the problem.I never had the column lock message appear before till now.I'm not with car now but as soon as I get there I will post again.
Thanks guys.

 

Last year when I changed the ownership over i had to get a recall done on the steering column.I'm not sure if it was a (4006c).The car is an auto and yes the steering column is locked now.It never locked last year when the car was running fine.I have never installed the column lock bypass.I'm not sure but I don't think the previous owner did either.I could be wrong.When I turn the key on a hear a short buzz like a solinoid releasing.The battery was low a number of times during the winter.Sometimes totally dead.I've had it totally charged now for 2 weeks and it starts every time.I had the charger on for 24 hours and the charger had turned off dew to auto shut off on full charge.Battery was new 1 year ago.It did not die from sitting.I had left the hood open while working on it and the light killed the battery.DOH.Problem is stalling,not starting.Voltage gauge reads 13.5 while running.
Thanks.

 

Damn stealerships ... if your steering is locking, and you have an automatic, the 4006c recall was not done, or not done correctly, as that recall specifies the removal of the locking plate, which means the column cannot EVER lock ........ the pin has no plate to lock into .....

The reason I was recommending the jump for the battery is that the column lock system has proven to be VERY sensitive to even the slightest drop in votage ..... basically as you turn the key to ON and then START the BCM expects certain signals from the electronic column lock in a certain sequence and a certain period of time. If it does not "see" the expected sequence, it tells the PCM the column is locked, and the PCM shuts off fuel when the rear wheel speed reaches 2 MPH.

So, some folks have found two "tricks" to get the column to unlock .... one is jumping your battery to a running vehicle in the hopes that the voltage "jump" will allow the column lock to cycle correctly.

The other "trick" some people have found is when they get the key to the ON position, if the lock pin does not withdraw .... then fairly vigourously rotating the streering wheel left and right numerous times against the lock (basically "banging" the lock pin against the lock plate) in an attempt to "break it free" will allow the lock pin to withdraw. Listen for the sound of the pin withdrawing ... you will of course also feel the heel free up if the pin withdraws. Once it withdraws turn the key to START and the BCM should indicate to the PCM that the ECL is now "unlocked" and the vehicle will now run correctly.

If that doesn't work .... With the key ON .... delete the error codes in the BCM for the column lock .....B258x then turn key OFF and remove Fuse 25 from the Instrument Panel fuse block and leave it out for 10 minutes. Replace it and try starting the vehicle. Hopefully this will cause the column lock to unlock.

Once you get the column to unlock, you need to install either the GM Harness K which should be on the car, but it doesn't sound like it is .... is part number 89023816 and list price is $114.04, or you can order the Column Lock Bypass from this site ... $44.95

The cheaper one is actually the more reliable fix. Order ASAP so this problem never bites you again.

Let us know how this goes ......

 

Thanks again.I will send you a PM.
Take care.
