What does GTW-W344 mean?
Tesla warning code in the Gateway (GTW) module. On rev E Media Control Units (MCUs), the MCU is capable of detecting the status of connection to the microphones by measuring the MIC-DIAG voltages. This alert is set when the voltage is out of spec (< 200mV for short-circuit, > 1200mV for open-circuit)?? in any of the four failure modes (L-open, L-short, R-open, R-short).
