A Prius owner that lived in New Orleans and had no power for days, used his car to run a light and some phone charging devices for a week or so. I though it was pretty cool to be able to power some lights with your car :love_shower:

Generic code readers won't cover much. If you can't read more than generic data, you could be fooled into believing the system isn't setting any codes because the scan tool can't read them. Uxxxx codes are the most common fault codes for intermittent glitch faults. When a module on the buss fails to send a signal out, the other modules will report it. U codes are communication faults and no generic code reader will see them. Most generic readers will read only the emissions codes as designated by the DOT.

So how is that Ford's fault ???? Sounds like your dealer is incompetent and could care less about you. Are you a chronic complainer ?

Programming resets the KAM in all the modules. It's gonna take some time for it to set all the adaption fields. I've heard 30 days is the magic number ?

Where did you get the light kit ? Got any links ?

So after buying my C-Max and finding my 12 volt battery consistently at 50% SOC, I started a quest to monitor it. The day after I brought it home, it was showing 50%. The car sat on the lot for awhile, so I accepted the reading as "LOT ROT". It's the term we have for vehicles that sit around for extended periods without use. I charged it and kept an eye on it. It kept dropping to 50% SOC after a week or two. I kept recharging it and started a daily voltage check. It continued to drop. I tested the battery (it passed) and did the Ford software updates. IT was still dropping off. I noticed my USB thumb drive was being pinged with the key off. I unplugged my USB drive and my iPod, because the iPod is charged by the system. It's been about 3 days and my battery voltage this morning was 12.68 volts. It's never been passed 12.2 before this change. I'm still in the process of monitoring the system, but this shows a change. I have the Sony audio system with dual USB ports. If the system is pinging a drive and charging a device (iPod) with the key off, then that means the audio system is keeping itself and other modules online. Modules that are awake use more than the nominal keep alive memory voltage and can lead to a dead battery. A compromised battery will fail very quickly without notice. The C-Max doesn't use a conventional starter, so you never notice the battery getting weaker and weaker until it's dead. I'll update this thread as my monitoring continues. Please check and make sure you don't leave anything plugged into the USB port. Maybe Ford will change the software to turn off the USB port when the car is shut down ???? I don't know if it's a viable fix yet, but the voltage change is telling me something isn't the same. The USB devices are the only changes I've made. Eventually, I'll do a parasitic load test to verify my finding. I won't be returning my car anytime soon. Sorry to hear you can't hold off until a fix has been made for yours. Good luck!

Did you zero the lifetime data after the update ? That's what I was referring to. I use trip #2 for my lifetime data and trip #1 is my per tank data. The software update will cause adaption resets and the car will need time to adapt back to you. The mileage/mpg data will also zero and adapt it's tables and re-plot the values stored in the tables. This will take some time, so be patient and let it settle in. I would also make sure the dealer didn't change my tire pressures. Some states (CA) require tire pressure checks every time the car is in the shop. If you run a higher pressure ( I run 55 PSI) and they drop it, you'll see an MPG loss. As stated by others. Cold weather with the use of the heater, defroster, and other power consuming features will lower MPG numbers. Rain is a big factor too.

Software updates are coming out all the time for new cars. First year models are always heavily updated. It's not unusual for this type of thing. You're just not being realistic about buying the newest technologically advanced car. The system improvements are for your benefit, so you should have a little better attitude towards your cars needs. REMEMBER: It's a first year product and you opted into early production ownership. Relax and enjoy the whizzbang ;) You could hold off a little while between visits, but then you'll still have some bugs to deal with. Maybe go into the dealer every 3rd update ? That will slow your trips to the dealer. Myself, I would go ASAP and not make an issue out of it. Would you be posting anything, if things were reversed ? It seems like most people only post if they have something to complain about. Not many post how happy they are when the car isn't in need of something...... :victory: I'm 110% happy with my car. It's been a great vehicle and the love affair rolls on :wub2:

A Scan Gauge II will read PCM DTC's. I don't know it's limitations, but IIRC, it will read only PCM DTC's. I also don't know the limitations the engineer mode, but it's a good start. Anything is better than guessing and monkeying around with the sensors, actuators and switches, without knowing what system is causing the light. An MIL will turn itself off if the system fault is no longer present. I think it's set at 3 clean drive cycles before it will turn off automatically. You could buy the Auto Ingenuity Scan Tool, with the Ford enhanced pack to read all the modules. I don't know of any other tool besides the IDS that's capable of reading them all. That's about 450.00 bucks :drop:

READ the STORED DTC's and quit trying to guess what is wrong.. Man!!!! You just refuse to listen to good advise.

Yes! At least use a comprehensive diagnostic tool to read stored DTC's... Only the IDS will read 100% of the systems fault codes, but some better tools can read most PCM codes.

Don't forget to reset the system :victory:

After unplugging my iPod and my USB thumb drive, I have had good battery voltage readings after a 100% recharge. Today's battery voltage reading was :flirt: 12.68 volts :happy feet:

When you select the PCM to update, the IDS will update other "related" modules. I don't know if it actually updates all as a gateway controller ? It probably will ? I know it updated 5 modules the first time, I did mine. Those modules are listed in my first post in this thread.

FIXED! ;)

Have them print the data from the IDS or at least take a photo of it :camera: IMO, this information should be available to all owners.

You still don't comprehind................. the MIL will come on for over 1000 possible problems..... THAT's THE BOTTOM LINE! Guessing why it's on, is like expecting to win the lottery every week :lol: :lol2: :clapping: Why do you think they make diagnostic tools for dealers/professionals ?

They update the IDS software twice a month. Today's cars always have new software available. Especially 1st year models. My current version is 87.01 and should be updated today ? I'll find out later on today. After they update the cars software, the IDS will show the calibration ID's after the update. Here's a sample from Aug. 19th when I updated my new car the day after I brought it home.

Make sure you aren't connecting to B+.......... Make sure it's a switched power source. WAB! What the heck is that hose clamp setup for on your power stud ?

The dealers "SHOULD" pull all system DTC and note them on the repair order. Most don't because they're to lazy. The IDS will even print the data. If it was my car, I would ask for a printed copy of the stored DTC's :victory:

OR.................................It could be any one of these few causes ?????????????????????????? I like how you edited the information to suit your point. You left out the FACT, they never said anything about the Check Fuel Inlet light coming on. How convenient :drop: We can guess till the cows come home, but the fact remains... If you don't know what the system is seeing as a fault..............It's a total waste of time futzing around with the computer sensors, actuators and switches. You can cause more codes to set and cause the dealer to miss the actual problem(s). Here are just a small sample of issues that can cause the MIL to come on. Don't forget we have about 10 more modules that can add to this list. Each one has it own code set that you can't read unless you have an IDS.

This list doesn't even include the CAN system codes. If a module has an intermittent loss of communication on the buss, it will set a Uxxxx code and the MIL will turn on. Flipping the flap wont fix it..... :spend: :spend: :spend:

Opening the door activates the interior lighting and the exterior lighting. This will drop the battery voltage reading. Next time, just pop the hood before you exit the car after you park it. That way, when you want to check the batteries static voltage you won't cause the voltage draw and you'll have an accurate voltage reading. Otherwise, you should wait about 10min. after the lights have been off to get a voltage reading. I prefer to check it without causing a system load before I check it. It's a more accurate gauge of your battery voltage.

It's not meant to be rude! It's meant to be direct... To the POINT No sugar coating for those that for whatever reason need to have it sweetened There is a difference, you might like to explore it yourself. Thanks for your input, but being direct is easiest. No need to wonder what I'm saying or what I mean.......... ;)

Yep! I don't call the kettle black. I sure don't assume I know it all, but not knowing anything about this cars systems and playing with it's sensors, switches, and controlled actuators is crazy. Would you open the back of your electrical panel to access the direct power buss and poke around with a screwdriver because the light in the fridge isn't working ? Then when you get electrocuted, sue the power company and complain about how problematic their product is ?

I see you too enjoy the guessing games and have problems when someone talks straight/directly about things. If you can't handle the truth, please don't respond to my post. Better yet, just ignore them and you'll be a happier camper. Thanks! Happy Motoring!
