For 2021 jeep wrangler jlu. I didn't do auto pairing. My friend's store hasn't received the 2021 software update in their scanner yet. I had alphaobd on my phone and a bypass cable. I tried to do a role detection but it was still not detected. I had to ask my friend to scan the sensors to get the serial numbers as they were already installed. After getting the serial numbers I entered them manually using alfaobd and ran the roll test again until all 4 were found. All 4 pressures are displayed but the light is still on. Update: One month after the reset, the light is still on. Continue reading codes Locate test failed or Locate test failed. The print is read but the light stays on after clearing the code.
