Tpms Light Flashing

Hello fellow DN'ers,

This vehicle has the TPMS light flashing, TPMS message flashing and a beeping in the cluster all the time. Customer brought in after another shop replaced the LR sensor and told the customer to drive it until the light went out. After several days of beeping they brought it to us.

I first scanned the TPMS module and found no codes. Then I tried to relearn the sensors but I could not read the newly installed LR sensor. Found said sensor disconnected from stem and bashing around in the tire. Replaced sensor with direct fit aftermarket sensor and again attempted a relearn. Relearn tool will not write to module according to display (Bartec 400). Scanned module with scan tool and was able to communicate. No codes. Data stream does show id's correctly but pressures inaccurate. Checked powers and grounds to module. Good. Being unsure of what had transpired beforehand, I decided to replace the module.

New module installed and another attempt at relearning with similar results. Now the light is just on. Bartec tool still states no relearn but sensor id's are indeed in there. Pressures show at 145 psi. I decided to try relearning for the non-Touring model. Now the condition is back to beeping and flashing. (ugh) Tech support at Bartec was unsuccessful.

Any thoughts on what I am missing?

If the ID numbers are correct I would try to fill all of the tires to about 40 pounds then lower them one by one to around 20 pounds. Fill them back to proper levels and then test drive. See if that works. I don't know how many options you tried on the bartec tool maybe try a year newer and not the touring to see if that changes anything. Chris

I did try a year newer since it was a late 2011 to no avail. There was a note on the tool about that procedure you described but it stated it was applicable to only the replacement sensor(s). I did not do that to ALL the tires but I'll try. Thanks!

The ones we have done required us to use the OBD connector with our TPMS tool (ATEQ). Have also had some issues with AM sensors. If using them, I like to see if the system will relearn before I even put the sensors into the wheel. Program first, then put tool next to new sensor, not even in the wheel mounted yet, while doing relearn. Saved us some time for a few possible headaches like this.

Hi Ric: You mentioned Bartec 400. Did you mean that designation? If memory serves, the older tools (WRT400 & WRT400Plus) had a separate Accelerometer initialization procedure. I don't recall when it was incorporated into the single procedure though I'm not sure that it ever was on the WRT400. (The 400SD and 400Pro and have the incorporated procedure. The 400Pro is a rebadged 500.) I've…

Try registering the sensors using a scantool. Go into functional tests- write ids and then use Bartec to ping each wheel. I had a few Hondas that needed that treatment for some reason. Light should flash fast until you hit correct speed and then go out.

Use dealer factory genuine tpms sensor only. I ran into that before with aftermarket sensors. I use Ateq tpms tool

Hi Ric, Are you sure that the reading is in Lbs instead of KPa? 145 KPa is about 21lbs. To finish process you have to deflate all four tires then re-inflate during the process. The new Bartec tools will give you these instructions. TIA publishes this. You can also find in service information. Instructions are 1-Inflate tires to placard (normally on door frame) 2-read all sensor IDs 3-Key in…

Thanks to all. The instructions on the Bartec Tool stated to perform the pressure drop procedure on 'replacement' sensors, not ALL sensors. After several attempts of pressure drops/inflate/drive I was finally able to get the light to go out. I have done many Odyssey relearns and never had this much trouble. Perhaps unique to the Touring? The Bartec tool has been great and their support always…

Great job on that van. I think that is unique to the Touring model. I have done many Honda's and usually its just beep the info into the tool and plug the tool into the car. At least, that is how it is on the snap on tool. I did have a odyssey touring and had a bit of trouble with that one. I was reading through the replies because I was going to ask you if you were sure it was a Touring model…

Ric, I am glad you got it figured out. Problems like these will keep one up at night.
