DTC 25

CONDITIONS FOR SETTING THE DTC
Engine Start Without Slip Ring Communications During key reading the body control module (BCM) checks the engine speed from the powertrain control module (PCM). When the engine speed is above 500 RPM the BCM will start a counter to track the number of times the key has been powered up without a valid message being received. When the counter exceeds 20 the DTC is set. This corresponds to 5 seconds of invalid key communications after the engine has been started.
