Tpm(tire pressure monitor) light indicating low pressure when there is no error. dealer (san marco,texas) claims the issue is due to cell phone charger interference with tpm system. dealer claims honda is aware of the issue and sent out a service bulletin to limit the cell phone charger to less than twenty minutes to prevent the tpm fault code and dash light from being set. in my professional option, honda america has what is known as a 'conductive electro-magnetic interference" issue with their system. based on what has been communicated, i believe there is an elementary design flaw with their system that allows either the transmitted energy or internal generated signals of cell phone to be coupled into their system using the battery lines. *tr
