"How- to" Access Advanced Ford PIDs Using a Scan Tool

[breeves002]

So I finally got another ELM and modified it (since selling mine to a member here), and did some more digging!

I found out that you can read your exact tire pressures in PSI through MS CAN and the SJB! My tire pressures were near spot on I had them filled to 33PSI cold, they are at 33PSI cold (almost).

I also found out that you can access your PAM module (either MS or HS CAN depending on the car) and see exact distances things are behind you and what sensor is reading it. Can do this with the BLIS radar as well. I'm assuming you can even do it with the ACC radar as well. Pretty cool way to see if the senors are working the way they should. I found after I cleaned the sensors really well they had a much longer range. It went from 255 to like 175 right away and now it goes from 255 to 225 instead then slowly goes down. 255 = 8 feet I think.

Any updates on this?  I want to get a new interface but I've been holding off.  I have a kiwi wifi and want to get something as fast as possible.  Even the delay in the factory tach bugs the hell out of me.  I have a new nexus7 2 coming so I think I need a bluetooth model?

OBDLink MX seems to be one of the fastest out right now. Honestly unless you get something wired thats snap on brand you're not looking at anything thats going to be less laggy than your tach.

My OBDLink SX connected to my computer with ScanXL is not very laggy, but again thats a computer with professional software and corded transfer.

No new updates really. Haven't heard back from adelsin about what modules he found!

I was looking through my workshop manual and found this info.  I thought you might be interested.  Also we were both right, the 13 has a bcm and the 3 networks connect to the DLC (data link connector) located under the instrument panel AND the bcm.

"Gateway Module

The Body Control Module (BCM) and Instrument Panel Cluster (IPC) are the gateway modules. The BCM translates messages on the HS-CAN to the MS-CAN and vice versa. The IPC translates messages on the HS-CAN to the I-CAN and vice versa. This allows a message to be distributed through all three networks. The BCM and IPC are the only modules on this vehicle that have this ability."

There is also a giant list of messages broadcast by each module and the module(s) that receive the message.  Let me know if you want it.

Interesting. There is MS, HS, and I CAN.

CAN has been going through the IC since it came out in 04. It's where HS and MS CAN meet up in my car.

Found out about a few more modules today.

The HSWM which is the Heated Steering Wheel Module. Pretty self explanatory, and then the IPM-A or Image processing module A which as far ask I know is for the auto dimming high beams.

The auto wipers may go through there as well.

Figured out what the FCM does too. Central hub for PATS and all the proximity sensors including the buttons on the door handles and keyless entry.

Hi all. Sorry all b/c my english not good.

I have some question for modify a cheap ELM327 clone.
1. Baud rate of MS-CAN is 125k and HS-CAN is 500k. Why we convert 6,14 pin (Chip ELM clone) to 3,1 (DLC connect  to vehicle) run diagnostic MS-CAN module good? Because of it is different baud rate. I think FORSCAN app setting baud rate for ELM327 clone dongle!!!.
2. Dose ELM327 clone have set AT command same ELM327 by elmelectronics.com ? and we can setting baud rate by AT command?

Thank all very much. Have a good day for all.
