Hi guys,
I cannot read the pressure of the 5th and 6th tyre. I assume they are not connected to the tpms.
Do you know how I can solve the problem?
Also I don't read the Tyre Temperature PID. Moreover, I don't know which of the Tyres this PID refers to: the tyres are 4 + 1 (0 4 + 2).

Thanks!!!

What are you using the 5th & 6th wheels on?
The Australian model needs the 5th & 6th wheels activated via Forscan
Do the extra wheels have sensors fitted?
The wheels have to be turning to register, they sleep when stationary.

Thanks so much Ross, I'll try to check on Forscan.
Could you kindly tell me what the PID Tyre Temperature refers to?
