Why does this matter? Many cheap cables fail when the alternator voltage spikes or when the glow plugs cycle. A "heavy smoking" environment is the ultimate torture test for a diagnostic interface. Voycom units that bear this unofficial certification can read real-time EGT (Exhaust Gas Temperature), boost pressure, and injection quantity even when the tailpipe is belching black carbon. voycom heavy smoking verified
If your soot load is between 30g and 45g, and the oil ash volume is under 60ml, you can likely cure the heavy smoking with a forced stationary regeneration using Voycom. In diesel slang, "heavy smoking" refers to a
Once you have performed a successful forced regeneration or replaced a faulty EGR/DPF, the "Heavy Smoking Verified" status may persist in the ECU memory. You must manually clear the learned adaptation. Critical Step: Turn ignition OFF for 30 seconds
