Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Can I ask why you replaced a PCM and a BCM at the same time?
If replacing any module, it would be normal practise to reset it to unlink it from the vehicle, replace that module, SPS program it to the vehicle, etc.
Did you do this to each module?
Did either one work prior to adding the other?
Ok, sorry to hear that, and I'm not laughing, I have seen it before, happens to many people.
How did you program the modules? Via TIS2WEB?
During BCM replacement, is there different options for new PCM as well etc?
Keys were programmed?
I would prefer to have both modules programmed by a Chevy dealer.
Did you link the modules together?
The keys would need to be programmed.
Please don't be upset about this, I have seen the results of welding many times.
We had one car that we could not eliminate an engine code that would keeping relogging.
Eventually worked out the frame had been electromagnetized from welding.
I hope my advice has been of assistance to you.
If you have fitted everything already I would say 2 hours of programming setup will have it running.
The GM programming tools are the best way to do any of this.
Do you have a GM dealer nearby?
You need to take the vehicle with the modules, preferably fitted, but ok if not fitted.
And all keys, preferably at least 2.
So that does mean towing it there on a truck.
I have done this a few times for smash repairers etc.
Have you made any progress with your problem?
The starter not working will be because the programming hasn't been done yet.
I have done this sort of job a few times to save large towing fees for customers.
You might find a dealer who is willing.
There may be a tuner out there who can disable the passlock, but I advise to get it running from the GM programming platform.
Hope it works out for you soon.
Oh ok, you have hurt the starter motor as well?
Sorry to hear that.
How have you gone with this problem?
Have you had a dealer sort it for you?
You are welcome.
Try and stay out of the heat.
Have the modules been replaced by the dealer?
Does the engine run now?
No you cannot get spark from the battery, how many more components do you want to blow up?
That's disappointing if they can't diagnose it.
It should log a code if it starts then shuts down.
It won't be a cam or crank sensor doing that.
I have had 2 customers cars that had issues after welding done on them.
Both similar faults on a Cruze.
Engine light, falsing camshaft codes.
I hate rudeness, that gets people nowhere.
I do hope they can sort it for you.
Are they still looking at it now?
I would think they should be a little more helpful.
A poor ground could cause this, but the dealer should be able to find things like that.
Have you got your vehicle back now?
Do you have another dealer nearby?
Stupid of the dealer to not help you, now they lose yourself and your circle of friends etc.
The dealer has done all the programming for you?
I can't understand how they can't work why it now runs then stops.
I think they have forgotten part of the key programming sequence.
Let's hope the next dealer may help you.
You can try the sensor, but I'm still dubious, since your dealer doesn't know.
Embarrassing for them.
I'm sorry I can't offer much more at the moment.
They must not have any 'big guns' working there.
I love jobs like this, because the young guys have no clue about it.
If the question times out, come back with a new question if you need to.
That is interesting and unusual.
I don't like the sound of that either.
Have you queried the dealer about that?
Have you looked around for another BCM in a wreckers yard etc?
Yes, try another dealer, tell them what has been done so far.
They might know what to do.
If the part numbers are the same, they should be the same.
The serial numbers are individual numbers to each assembly.
I think you mean the upper and lower shafts, so I have attached what you need here.
How are you going with the BCM issue?
I hope this helps.
Are you wanting to replace the steering column?
There are a few special tools required to disassemble the column assembly.
Here is the removal procedure.
I hope this may help you, and I hope my advice has been of assistance to you.
