Hi,
I was wondering if anyone recognizes the tone which is attached. It is coming from what seems to be behind my dashboard. It only sounds off sometimes, especially before the car warms up.
Thank you,
Steven

 

That's the alarm you hear if you turn off ignition when the trans is not in Park.

 

Thank you so much!!
Why is this alarm going off while I'm driving? Exactly where is this alarm?
Thanks,
Steven

 

The speaker is in the steering column I think, but that's not your issue.

The BPM provides the alarm to the speaker. I have no idea really why it would do that while driving. There's obviously some input it's receiving that it shouldn't (or some input missing that it should have) - so a faulty cable connection or a short to ground somewhere? Or it could be an internal fault in the module.


You will need to test with a multimeter at the BPM to try and work out what's going on. As the fault is intermittent that's going to be tricky. I've attached a spreadsheet I did some time ago that shows all of the BPM pins and functions so that may help in your investigation.

You might want to start with Pins FC2-31 and FC2-48 which are both inputs to the BPM from the ignition switch.

 

Wow, this will be extremely helpful. Thank you
