So, my car has the iTPMS. No value showed, just ok and not-ok
But I don't have keyless entey (unfortunately)
Could I just activate dTPMS and it will work? Or I need the new sensors as well?
I'll see if I can sort out. Let me know if this clears it up, or makes it worse hehe...
- If you have iTPMS, you do not have TPMS sensors. iTPMS uses ABS wheel speed sensors and some fancy math to monitor the tire pressures. It doesn't display pressures because it can't.
- The Sensus based cars, support both systems (iTPMS and the sensor type of TPMS), this is a config you can change with OrBit.
- To change the config, and use sensor type TPMS, you must install compatible TPMS sensors in the wheels for it to work.
- The TPMS sensors need to be compatible with Volvo, and use the same frequency as the remote key fobs in your car (could be either 315 or 433Mhz)
I am not sure that the car is required to have the keyless operation, it just needs the antennas present in the car. Are you saying that you do not have any keyless entry at all, the door is unlocked with a key only? I can't imagine that is true..but I am in the US all the Volvos have the totally keyless operation.
What model do you have? I could help you sort it out if you wanted to do this. First would be to take a look and see if the antennas are present, regardless of what remote system you have or don't have. While only a single antenna is needed for simple remote lock/unlock system, the multiple antennas that can track location may simply be the same in all cars. If the antennas are present, it should be possible. It is also possible the Sensus supports running TPMS with a single antenna system, there are config items for it I believe, and the locations of the wheels do not need to be "auto learned" like the multiple antenna system can do. You can set the TPMS sensor IDs and locations with OrBit.
