BCM replacement instructions with location please?

Here are the BCM replacement instruction in the diagrams below. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

To me it sounds like the BCM is going out which is common but we should check the electrical connector for corrosion as well. Here is the location of the BCM and how to replace it. Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Hello,

If I can jump in here it sound like the BCM is out. To be sure lets do a CAN scan which is the future of automotive repair you can get a CAN scanner from Amazon for about $50.00. here is a video to show you how. (no subscription needed)

Here is a guide to help you step by step with instructions in the diagrams below to show you how on your car to replace the BCM. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Hi dekpenek! You need to get a scan test this video will show you how. You can get a preprogrammed unit just give your VIN when ordering it.

Let me know what codes you retrieve. If you need the BCM replace the instructions to do so are in the diagrams below.

Hello,

I have seen the BCM out which cause this problem. Here are the security system wiring diagrams so you can see how the system works and the location of the BCM which will need to be programmed to work.

Body Control Module (BCM) Programming/RPO Configuration
Important: If the module is replaced, programming the module with the proper RPO configurations must be done prior to performing the Passlock Learn procedure.

The BCM must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options. If the BCM is not properly configured with the correct RPO codes the BCM will not control the features properly. Ensure that the following conditions exist in order to prepare for BCM programming:
The battery is fully charged.
The ignition switch is in the RUN position.
The DLC is accessible.
All disconnected modules and devices are reconnected before programming.
Follow the SPS instructions on the Techline Terminal and scan tool to program the BCM.
If the BCM fails to accept the program, perform the following steps:
Inspect all BCM connections.
Verify that the SPS Techline Terminal and scan tool have the latest software version.
Passlock Learn Procedures
Refer to PROGRAMMING THEFT DETERRENT SYSTEM COMPONENTS for the appropriate learn procedure.

Important: After programming, perform the following to avoid future misdiagnosis.

Turn the ignition OFF for 10 seconds.
Connect the scan tool to the data link connector.
Turn the ignition ON with the engine OFF.
Use the scan tool in order to retrieve history DTCs from all modules.
Clear all history DTCs.

I would try unplugging the BCM and then plugging it in again which can solve a bad connection issue.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken

That would be a first, I have not heard of such a thing. Here is the information that I get, which sheds no light.

The BCM could be an issue. However, most often it is the float rheostat that is part of the fuel pump. Before I replace the BCM, I would check wiring to the top of the fuel tank to make sure there is no damage there and also make sure the system has a good ground and corrosion isn't an issue at the plugs.

If that all checks out okay, I would then check to make sure there is a signal from the rheostat in the tank. If there is a signal, no wiring problems, and all grounds are good, then I would consider the BCM but to be sure lets do a CAN scan which is the future of automotive repair you can get a CAN scanner from Amazon for about $50.00 here is a video to show you how.

You mentioned the vehicle has a misfire at times. Have you checked to make sure the fuel pump pressure is within spec? Also, has the check engine light come on indicating there are trouble codes stored?
