Hi John

How are you doing? Is there any history of BCM replacement? Below is what it looks like

The automotive central body control module (BCM) is a processor-based power distribution center that supervises and controls functions related to the car body such as lights, windows, security, door locks and access control, and various comfort controls. If the BCM is faulty you'll encounter problems like you are having now. I'll be standing by for your response. Thank you.

Regards

Relly

I see... I suspect the BCM at the moment and it will require replacement. I strongly suggest that you take it in to a reputable auto shop for a physical check up John just to be sure.

I see. The ECM (Engine control module)  is a computer that controls the engine and all the sensor that works within. The BCM (body control module) is like a brain that controls all the electronic function of the vehicle. For example below.

BCM

The ECM and BCM has a complete different function John as you can see from the pic above. Atleast its a good sign that theres no fault showing on the ECM during the SCAN

Is there anything else I can add or help you with John?

Usually it is located underneath the dash John. May I ask the exact model of your Volvo so I can check wheres the exact location. Some do reflash the BCM before replacing it. There are shops and electronics center that do this.

Its underneatht the dash John

Actually you can get one from a yard near you just to check if it will work John plus its much cheaper

Hi John yes it's like a fuse box with lots of relays on it. What I showed you is just a reference. Yes sometimes they will need to be reporgrammed but you might want to try to install it first because some doesn't need to.

When do you plan to install it John?

I see.... You'll be good after the replacement John. Anything else I can add or help you with?

Dear John, It was a pleasure helping you with your VOLVO issue today. Here is a summary of the resolution.

Issue identified : All electrical function is not working
Solution Implemented : Chat and called John. This is usually a failing BCM because it's the brain of all the electrical functions inside the car that if it's faulty this issue will occur. Solution Accepted
If issue resurfaces : Advised to contact us at s**t@experthelp.com or call us on our support number ***-***-**** )

No worries John.. you have 30 days to communicate with me. You may email me at d**9@yahoo.com as well for any additional information. You have a good one!

Hello John

Good to hear back from you. It's good to know that other electrical functions are working now. Here's some few reason why it will not turn over even if you have fuel.

1. Faulty starter

2. Failing crankshaft position sensor

3. Failing coilpacks

4. Failing sparkplugs

I am suspecting that the crankshaft position sensor is failing. Is there any history of crankshaft position replacement? The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed (RPM) of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. I'll be standing by for your response. Thank you

Relly

There's no relationship between the two John. When you start the car, will it crank?

Good to know that the starter is live. Yes you may want to have it rebuilt as well and see for yours can be fresher.

I would try to remove the starter and test it using the battery and see if it will kick

Looks like that it's the neutral switch that needs to be taken care of John because the starter looks pretty good to me.
