High-Soot-Load Idle Shutdown

Extended idle operation can cause soot to accumulate in the DPF, which can eventually trigger an ECM fault, cause the Stop Engine lamp to illuminate, and require replacement of the DPF. The High-Soot-Load Idle Shutdown feature (if equipped), determines if the extended engine idling needs to be shut down before there is a triggering of the stop engine warning.

The High-Soot-Load Idle Shutdown feature monitors the soot load during the idle or high-idle operation. If high-soot-load occurs, the DPF lamp will illuminate, then the Check Engine lamp will flash for 30 seconds, before the engine shuts down.
