TPMS Programming Troubleshooting

[jbrown9999]

I put 18's on mine and got new TPMS sensors from Tire Rack with the rims and I have had no issues.  So the rim size isn't relevant.

Thanks, jb. Seeing as how many,many others here have done this, I was only 101% sure the rim size wasn't the issue. It was more to showcase the incompetence of the dealer. Haha

It does appear that 2015+ vehicles switched to TPMS35 sensors (still 315MHz), which are not compatible with my vehicle. However, seeing the obvious difference in sensor shapes, I'm 1000% sure I do not have the newer TPMS35 sensors.

My installed sensors at least look like TPMS12 sensors, which is what my vehicle called for.

Well here's the 18" wheels and Ford TPM's I bought that were off a 14 and I put them on my 16 and I had no relearn or warning light issues..zero

Hmm. Do you know whether or not the sensors were OE or aftermarket?

He told me they were Ford sensors

Mike, are you still battling with this issue and did Ford leave you hanging?

Not sure if he got it fixed, but I know the trip to the dealer was not successful. I think last I remember he was looking into modifying the BCM with forscan?

Hey guys! Thanks for checking in. Been a busy couple weeks.

So, the short of it is, I still have the issue. I'm not super confident in paying the dealer for additional troubleshooting, so I'm still planning to go it alone until I exhaust all troubleshooting options.

I did end up getting FORScan (why do I read foreskin every time I see that?? lol), and pulled the following codes off the BCM:

===BdyCM DTC B1182:00-08===
Code: B1182 - Tire Pressure Monitoring System
Status:
- Previously Set DTC - Not Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC

and

===BdyCM DTC B124D:02-8A===
Code: B124D - Tire Pressure Sensor
Additional Fault Symptom:
- General Signal Failure
Status:
- DTC Present at Time of Request
- Malfunction Indicator Lamp is On for this DTC
Module: Body Control Module

I tried clearing the codes and reprogramming, but was unsuccessful. My next step is to go through the pinpoint tests in the manual which correspond to the above codes to see where I arrive.

I did confirm with the FORScan (foreskin) developers that it is NOT possible to manually program the BCM with the TPMS sensor IDs. Evidently the IDs can be read from (but not written to) the BCM.

On the F150 forum, there's a ~550 page thread discussing FORScan changes, and one of the items listed in the master spreadsheet is a TPMS disable/enable, but the BCM address given for the F150 does not match anything I have on my Explorer Sport, so I'm not sure if I have that option.

At this point, I've basically come to accept that I will likey just need to deal with the errors and flashing lights while running my winter wheels, at least until I need to change the tires again in a few years. At the very least, it would be AWESOME if I could figure out how to disable the system through FORScan, so I don't have to deal with the blinky-blinkey, dingy-dingy.

Once I go through the pinpoint tests, I will update on my progress. If anyone has any other ideas in the meantime, let me know!

Good luck Mike and certainly is a bummer when the so called pros drop the ball. Doesn't make a person feel confident going to the dealer

You already tried swapping back the "summer" setup, right, and it worked flawlessly?  Did the Forscan guys say there is a limit to the number of entries in the TPMS table?

I will have to say AFAIK code B124D accompanied by the dash light continuously staying on indicates that one of the TPMS sensor's is faulty and the dealer should be able to determine which sensor is not responding.  Z

Reading the description on those codes seem to indicate the same, that one of the sensors in the winter wheels is bad.

The Old ghetto way is to just tape over it and pretend it isn't there. Doesn't help with sound though, and if the warning is on the LCD (not sure since I have yet to see one), it would be a bit much to tape, but figured I'd remind you the ghetto way haha

The first thing I did when I couldn't get the winters to train was roll the stock wheels over. Those trained again with no issue. Unfortunately, the FORScan forum hasn't been very helpful. I've had a post over there for a couple weeks with 91 views and zero replies.

A dealer may be able to determine which is faulty, not sure about my dealer. LOL

I guess what's most confusing to me is that my fancy TPMS service tool can read all the "new" sensors just fine. Pulls the IDs, frequency, and battery status. If the scan tool can read the sensors, I would think the car should be able to read them, assuming everything is compatible.

FORScan is supposed to let you read the codes stored in the BCM, but I have yet to try that function; I may give that a go this evening after playing with my boost regulator springs. It will be interesting to see if it is sensing ANY of the new sensors, or if it still just shows the OE sensor IDs.

Also, if there's a BCM fault, would that prevent ALL sensors from training? I can't get any of the four to train, so it makes me think that either a) all sensors must be seen as present to allow training, or b) my "new" sensors aren't compatible with my system.

At the very least, it would be AWESOME if I could figure out how to disable the system through FORScan, so I don't have to deal with the blinky-blinkey, dingy-dingy.

In addition to the standard TPMS idiot light, there is also an awesome giant pop-up screen on the left LCD/Message center on the dash. The message center warning can be cleared by hitting "OK", but the TPMS light stays on. The chiming only happens at start-up, and occasionally after driving for 20 mins or so, but it only lasts 5-10 seconds, then it seems to go away until the next key cycle.

Thanks again, guys! I'll check in again later tonight if I get a chance to run through some additional scans and pinpoint tests.

I went through the pinpoint tests that correspond to my errors. I ended up at the bottom of the troubleshooting charts with the following suggestions:

1) Replace BCM
2) Replace faulty sensor(s)

Considering I can still train my OE wheels, I am fairly confident it's not the BCM, and I somehow ended up with incompatible sensors.

The last thing I'm going to try is ordering a new sensor from Tasca (based on my VIN) and see if I can get it to train. If so, I'll replace my sensors in the spring once I swap the OE wheels back on.

I was able to get into the BCM via FORScan and confirmed that ALL of the sensor IDs present in the module were still the OE wheel sensors.

I'll update again once I receive a new sensor to try. Thanks again for the help, guys!

Thanks for the update and damn those eBay sensors if that's what all  the frustration was about..
