[GPS upgrade 2009 MMH]

Yup, thanks. All good points. I kinda figure i wont find anything better than 200, but it would be nice. grin. Hey, we can dream. Now if only I were not the first one to do this to the 09 mariner. grin. It will prob be a couple weeks before I make the order. I can hope for the best.

 

Silver State Ford lists the DVD for $181.09, with a suggested list of $219.61.

[Tire Pressure Monitor Sensor Fault]

I am not familiar with the TPMS on the Escapes. All of the customers we have who own Escapes do not have TPMS. BUT, there are 2 basic types of TPMS. A dumb one and a smart one. The dumb one will tell you that you have a low tire...but not which tire. The smart system will tell you the pressure of each tire and which is low.

Whenever you rotate with the smart system you need to reprogram the system because the sensor is matched to the location on the vehicle. If a reprogram was not done or done incorrectly...it could be throwing you a code. IIRC some new systems are wanting you to drive a certain number of miles above a certain speed before the reset is complete.

 

Well, I guess the Escape's TPMS is a smart one, but dumbed down for the driver. Individual tire psi are available from the SJB through the MS CAN network via a mode 0x22 PID of 0xC127 for the 06-07's. Tire rotation shouldn't affect the system. Parking right next to another system or any other RF interference can, however, cause the system to require a re-train.

[Tire Pressure Monitor Sensor Fault]

Just got back from a little trip (about 350-400 miles round trip) with the family to go see my grandmother. Sporadically throughout the trip the "Tire Pressure Monitor Sensor Fault" message would come up in the display and the light would flash in the dash then stay on solid. The tires don't really look low, that and I would think that the message center would say something else if the air pressure is low. I checked the air pressure at some gas station and they are around 32-35 psi.

 

What's weird is we just got a DVD player that straps onto the headrest for my (almost) 2 yr old son to watch his Elmo movies while we drive. Its not wireless, it simply plugs into the Aux power outlet. It does have a remote control, though. I heard on other forums that the TPMS system is wireless and transmits via radio frequency to the controller. Could there be some RF interference going on with the DVD player? Like I said the only wireless thing is the remote which we didn't really use. I checked All Data and there aren't any TSB's related to the TPMS.

 

Vehicle just rolled over 6000 miles. Any insight would be appreciated. Thanks.

 

You probably just need to re-train the sensors. Discount tire did this for me for free but the tool to do it is <$20 and the instructions are in the shop manual.

[09 MMH, Scangauge and 4WD status]

I read the link. That's supposed to be 47.7% torque going to the rear wheels just taking off from a stop and no heavy throttle? What kind of system is in that FEH that allows that with what I'd guess is no front wheel slipage? It sure doesn't sound like the "on demand" 4WD in the current FE.

 

 

I have recently been able to verify with a Ford WDS system that the full scale reading for this PID is 100%. So the original coding was correct and 47.7% it is. Will post on CMP how to command this instead of measuring it.
