Circuit / System Description
Engine Start Without Slip Ring Communications--During key reading the body control module (BCM) checks the engine speed from the engine control module (ECM). 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.
