Fastronaut Report post Posted May 13, 2013 So I'm driving along and exiting a highway and turn on to the exit ramp. As soon as the car comes to a stop, on comes the Parking Brake Light and the car won't budge. Called the Ford Dealership Service Department and they never heard of this happening. Finally, turning the car off/on, moving shift lever repeatedly, etc. (a million times), the car starts to move in Drive even with the brake light on. I drove it straight to the Ford Dealer. The Hybrid Service guy (singular) is in a Hybrid class Tuesday-Friday this week, so guess what? OK, he diagnosed it from a conversation and thought it was something to do with the regenerative braking and someone else there can possibly handle it. Anyone else ever seen this problem?

hybridbear Report post Posted May 14, 2013 Sorry to hear about this. I'm glad you got your car finally. Please keep us updated on what happens. I don't often use the accelerator as my way to turn off the parking brake even though the car will do this because it seems like it would create extra wear & tear, but I tried to the other day and had it not work for the first time. At a traffic light I put the car in neutral since it was going to be a long wait. I then put the parking brake on and took my foot off the pedals to rest. When the light was about to turn green I put the car in drive and then figured I would just hit the gas to take off and let the car turn off the parking brake but it wouldn't turn it off so I had to push the button and then drive. I haven't tried this again because I don't want to have any problems. But after your experience I might try this again to see if it is an issue regularly 2 Fastronaut and GrySql reacted to this Quote Share this post Link to post Share on other sites

I am glad I'm not alone in this. It could be we both need a software update. I have the car at the dealers so can't try anything. If you find any reproducible problem to document a second case, That might mean Ford will pay more attention. Good luck. Anyone else put there - please check put the parking brake.

Fastronaut Report post Posted May 15, 2013 The dealer has had the car since Monday afternoon and has only found two electrical error codes, but is still going through diagnostics. Two other Ford dealership service departments that I have contact with have never seen, nor heard of, this problem. There are no TSBs or Recalls describing it. The analysis continues.

I tried it yesterday and this morning and the parking brake disengaged both times when I hit the gas pedal. It worked both going forward and in reverse backing out of my garage. I really like it because I found it a pain to manually disengage it every time I turned the car on (I use the parking brake all the time - habit from my old manual car). 1 Fastronaut reacted to this Quote Share this post Link to post Share on other sites
Fastronaut Report post Posted May 15, 2013 Update: Diagnostic testing finished and there were several error codes that lead the service technician to say that the best description he can give is that the Fusion Hybrid needs a new "Transmission Control Module". The dealer is sharing the diagnostic data with Ford Technical Support to see if they concur. Quote Share this post Link to post Share on other sites

I really like it because I found it a pain to manually disengage it every time I turned the car on (I use the parking brake all the time - habit from my old manual car).I'm glad that my "pain" is able to allow you and others more knowledge about the parking brake subsystem. Amazing how these Forums are such a valuable source of information.

hybridbear Report post Posted May 15, 2013 I hope they can get it solved soon! What kind of rental did Ford provide you with in the interim? Quote Share this post Link to post Share on other sites
Fastronaut Report post Posted May 15, 2013 I hope they can get it solved soon! What kind of rental did Ford provide you with in the interim?My dealer has an Enterprise Rental Car franchise located on-premises, so I got whatever they had. In this case a Chevy Equinox SUV.

Fastronaut Report post Posted May 15, 2013 OK, so it is looking like it is something to do with an OBD-II Control Module that has functional control over both the transmission and braking system. Dealership, with direct Ford Michigan Engineering help, has been able to isolate and get repeat failures. That's good news. Quote Share this post Link to post Share on other sites

GrySql Report post Posted May 15, 2013 (edited) Now looking like the Hybrid Power Control Module (HPCM)In your spec's I see you have the Luxury Self Defense Option (LSDO).Did they check to see if your Phasers are using too much of the HPCM for the Faster Than Light Drive (FTLD)? Or, maybe a Photon Torpedo Stability Interlink (PTSI) locked the car's position for launch.Who's the engineer working on your car, his name wouldn't be Scotty would it?

Fastronaut Report post Posted May 16, 2013 Failing part identified as Transmission Control Module, part number DG907B012E. Also called a Secondary Onboard Diagnostic Module. 1 neod192 reacted to this Quote Share this post Link to post Share on other sites
acdii Report post Posted May 16, 2013 (edited) Not too far from the truth. So many components now that intercommunicate that makes troubleshooting a chore. Someday an engineer will have a bright idea that will allow the system to self diagnose and say, Hi Im broke, please replace me.

Someday an engineer will have a bright idea that will allow the system to self diagnose and say, Hi Im broke, please replace me. Cars are getting to be computers on wheels today. It won't be too long before they download automatic software updates. After all, we see it on Synch now, or close to it. Unfortunately, the driver may still be the one who has to say "I'm Broke" before the execution of the update. ;) Quote Share this post Link to post Share on other sites
hybridbear Report post Posted May 16, 2013 The problem with computers diagnosing themselves is that they aren't very good at it because it means that someone has to write code to tell it how to do that. It just doesn't work well Quote Share this post Link to post Share on other sites

murphy Report post Posted May 16, 2013 I've never seen anything useful in a VHR.If I forget to release the parking brake before I run the report it gives me a warning that my brakes have failed and must be serviced immediately.The 2010 Fusion Hybrid did that in 2009 and I verified that it still happens in my 2013. 1 Fastronaut reacted to this Quote Share this post Link to post Share on other sites
Fastronaut Report post Posted May 16, 2013 Did you run a Vehicle Health Report? I wonder if it would show anything went wrong.No. You can't do it with under 200 miles and I haven't had the car home enough to do that, as crazy as it seems. Been with the dealer mostly.
