Dealership installed new tires and 4 wheel alignment. On way home got the TPMS/System Alerts which indicated that the Left Rear Tire Sensor was not responding. No TPMS Issue ever before. Have read that the sensors are self programming and can be told to re-program via the GAP tool. So thought, well, let me see. So went to ECU\BCM and found TPMS Spare, TPMS 1 and TPMS 2. Don't believe the spare has/had a sensor so it being none is ok. TPMS 2 is self explanatory and seems correct, but TPMS 1 has a LOT of settings, and the GAP manual that I have doesn't mention TPMS at all. So wondering which of the TPMS 1 settings it should be on to tell it to reprogram itself or is the command to tell it to do that in another section? And is the WBL setting the correct setting for normal use on US vehicles?
Strange that it developed after a tire change. TIA//
EDIT: Took a trip with system turned off. After returning home returned the settings to WBL (Wheel Based Localization)/INSTALLED and all returned to normal after a drive. Found out that TPMS_WBL does not work.
2nd EDIT: Turns out after next day failure again, dealership found left rear sensor was defective. They replaced it for FREE, and when the service manager noticed my Land Rover sport shoes decided I needed a genuine JLR Discovery ball cap! Great dealership service!
BTW - all those cryptic engineering flags (letters) are a part of the Land Rover Internal diagnostic abbreviations. MS COPILOT helped me out to decipher the meanings of those!!
