CUSTOMER CONCERN TPMS warning remains on, none of the tire-pressure sensors will train, and both keyless-entry transmitters are inoperative. CAUSE Confirmed failed Radio Transceiver Module, which supports both TPMS sensor reception and keyless-entry operation. CORRECTION Remove and replace the Radio Transceiver Module, perform the required TPMS sensor training, and verify TPMS and keyless-entry operation.
