Well I recently started getting check air pressure on my DIC. It was telling me my RR ( right rear ) was low. I added air to Right Rear... pass. rear tire.

Still getting the same notification with the lower ambient temps out recently. So today I get tired of it becuase it sticks around until my tires warm up... turns out my Right Rear is in fact fine and full of air... it's my RF or pass. side front tire that was at 26psi..... now wtf is up with that and is there anyway these sensors could have been thrown out of whack? I've touched nothing in those areas since I dropped it originally years back.

I'm getting a new set of rubber within a week the BFG KDW2's so i'll just roll with it until then just pretty curious. and I always keep a digital air gauge in the glovebox anyways... thats how much faith I have in TPMS.

The TPMS sensor matching process:

1. Set the parking brake.

2. Turn the ignition switch to RUN with the engine off.

3. Turn the headlamp control from off to parking lamps four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure.

4. Start with the driver’s side front tire.

5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with step number one. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key.

6. Proceed to the passenger’s side front tire, and repeat the procedure in step 5.

7. Proceed to the passenger’s side rear tire, and repeat the procedure in Step 5.

8. Proceed to the driver’s side rear tire, and repeat the procedure in Step 5.

9. After hearing the confirming horn chirp for the driver’s side rear tire, check to see if the TPMS warning light is still flashing. If yes, turn the ignition switch to LOCK to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.

10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.

11. Put the valve caps back on the valve stems The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the SERVICE TIRE MONITOR message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor.
