Invalid Data Received From Radio Transceiver

Check these first

• A weak vehicle battery browning out the radio transceiver during cranking
• A loose, corroded, or water damaged connector at the radio transceiver
• An open or short in the radio transceiver wiring to the module that receives its data
• A lost power or ground feed to the radio transceiver

What to do next

1. Scan all modules and record the stored and pending network codes
2. Check the radio transceiver data bus wiring for opens, shorts, and chafing
3. Confirm the radio transceiver reports correct live data on the scan tool
4. Repair or replace the radio transceiver if the circuit, power, and bus tests pass
5. Clear the code and retest to confirm the radio transceiver fault is gone
