Dear,

I would like to Thank you in advance for your help and time.

I have a Honda Jazz 2014 automatic and the TPMS light is on after opening the rear tyre to check the rear pad brake and I did check with Delphi diagnostic and showed me B1173 Fault - CAN-bus no communication with TPMS (Tyre Pressure Monitoring System)

Thank you for your help.
