MAN OF BLUES :
Finally figured it out, the libraries I was using didn't have any parameters for crystal frequency and therefore my baud rate was not correct.
Once I sorted that out I am getting data off the bus so with a little more programming I should be able to retrieve the data I need.
Thanks;
good luck with that.
If you read, what I explained that when a TPS sensor is installed, the sensor ID "must be manually input" thru the KDS, there by "creating a name" so to speak, all you will find is "sensor-unknown i.d.", and it won't allow it to be programmed to be linked to the ECU. via the sensor's internal matching ID code. Even the KDS 'sees' it... but it will NOT link it without that step. The KDS can't even "pull the code" from a sensor.. it only verifies it matches the coding number manually entered, and that matches the signal being transmitted during operation.
also note that all of these TPS sensors do not "broadcast" anything, unless the tire is spinning/rolling down the road.. sitting stationary it's a "turned off" unit.
I seriously suggest you simply peel the tire, get the code off the sensor, and be done. In the end, I think with all you are going thru, you will find this to be true.
