Gidday everyone. I have been chasing the same information regarding the TPMS recognising the new wheel placements after a rotation. Unfortunately, INEOS advice was to take it to the service agent and have them reset the sensors in the system. This is DEFINITELY NOT in line with the original Grenadier philosophy. Anyway, I have a solution that everyone can do. See below.
I have worked out how to do it. While it is fairly simple, it is a bit tedious. You MUST use a 5 wheel rotation, not 4. It is much easier to confirm transfer of the wheel sensor to the correct location if you have noticeably different pressures in the spare to the rear pair to the front pair at start. For example, have 340kpa in the spare, 300 in the rear pair and say 260 in the front pair. The difference needs to be sufficient that tyre temperature and pressure increase while driving does not confuse, of make the pressures overlap. As the system is only set up to recognise one wheel movement at a time, you must drive the vehicle after each change until the system recognises the new position. After this, you may then move to the next single wheel rotation.
1. Ensure your tyre pressures are set up in three different groups, spare, rear and front.
2. Rotate the spare to the REAR RIGHT. I am not sure whether there is a sensor in the rear door, or if the system requires the wheels to rotate to awaken the sensors. If it uses rotation, then the new spare may simply be placed in the rear of the vehicle. Take the vehicle for a drive of around 15 to 20 minutes. Have the Off Road Temperature screen on the display so you can see when the system recognises the spare is now at the rear right. The pressure display will change to the new tyre’s pressure.
3. Rotate the new spare (the wheel that was the original rear right) to the FRONT RIGHT. Place the original front right wheel in the back of the vehicle or on the spare carrier. Repeat the drive and monitor the pressure display until the new reading is shown.
4. Rotate the new spare (the wheel that was the front right) to the REAR LEFT side. Repeat the procedure for spare storage and the drive. After the system registers the new tyre pressure, go to the next step.
5. Rotate the new spare (this wheel was the rear left) to the FRONT LEFT side. Place the new spare in the rear of the vehicle. Repeat the drive procedure until the system registers the new tyre pressure.
6. Correctly inflate or deflate all tyres to the pressures you wish to run. Remount the final spare wheel to the correct location.
I hope this helps all those who have this issue. In my case, the wheels had already been rotated. I had to devise a way to achieve the desired end result while making the correct next wheel available as the next spare. If you are unsure of where your wheels actually are on the vehicle, try deflating or inflating one tyre at a time and watch the temperature screen in the Off Road group to see which position the vehicle thinks the wheel is in.
, but does the Grenadier automatically relearn the new TPMS locations?
