Customer Question
Hi I have a...

Hi I have a Chevy Silverado 2002 which was driven to Lowe’s parked but wouldn’t start after coming out I’ve told it home replaced the fuel pump thinking it was a fuel pump issue but it apparently it a electrical issue. The head light don’t work or any of the cab light. I have power to turn signals. I’ve check the components module it not the issue and the is a relay socket not getting power to the headlights and finally the security light 💡 won’t reset.

Yes

Mechanic's Assistant: Are you fixing your Silverado yourself? What have you tried so far?

Yes

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

do have a spare key that you can try?

If not try cleaning off that key where the pellet is and try again if the security light goes out.

If not, you may have to retrieve the trouble codes to find out why the security light is on.

What engine came in this and what ton is it?

I asked you what "reyes reprogramming" meant.

I asked you What ton this was?

You are going to have to retrieve the trouble codes, I am not going to guess what it might be.

If you were trying the 30 minute relearn procedure, did the security light ever go out after that 10 minutes?

Ask Your Own Chevy Question
Customer reply replied 4 months ago
No it never went out
Chevy Mechanic: Mike S., Chevy Mechanic replied 4 months ago

Most likely the code is in the bcm, so you would need a scan tool in order to read codes from the bcm, do you have a scan tool that can do that?

Ask Your Own Chevy Question
Customer reply replied 4 months ago
I tried swapping out BCM and it didn’t work
Chevy Mechanic: Mike S., Chevy Mechanic replied 4 months ago

For instance these codes.

Ask Your Own Chevy Question
Customer reply replied 4 months ago
I’ll try checking codes again in about an hour
Chevy Mechanic: Mike S., Chevy Mechanic replied 4 months ago

Do you have a scan tool that can read codes from the bcm or is it simply a code reader?

Ask Your Own Chevy Question
Customer reply replied 4 months ago
It’s obd11 reader
Chevy Mechanic: Mike S., Chevy Mechanic replied 4 months ago

Ok, a code reader cannot read codes from the bcm as far as I know. You need a scan tool.
