The 152-3431 detonation mixing control (DMC) will generate erroneous shut-down codes on the G3600 engine. The shutdown codes are generated, because the DMC allows incorrect information to pass through the communication error checking protocol. The codes include 501-10 (Noisy Ignition Signal Cylinder 1), 501-12 (No Ignition Signal Cylinder 1), and 190-12 (No Flywheel Signal). The 1776975/">177-6975 DMC eliminates the erroneous shutdown codes, because the communication protocol has been corrected to prevent incorrect information from passing through it.
