TSB 18-001-09: 6.7 L PCM Flash
« on: January 10, 2010, 04:52:21 pm »
The latest PCM software will include the following operational and diagnostic improvements: Improve engine cooling capability and prevention of over temp condition (P0217 - Coolant Temperature Too High) when operating with snow plow. New feature that allows for customer selectable remote PTO speed (if equipped). The latest ECM software includes a new extended idle feature to accommodate the extended idle times present in some duty cycles. This feature may help to reduce the accumulation of soot in the exhaust aftertreatment system when the engine is idling for an extended period of time.

To determine if the vehicle has the latest software, compare the following notes:
If the vehicle in question is a 2007 model year vehicle, then compare the current PCM software level part number to one of the following part numbers (or with a higher suffix):
52300430AX (or higher) = DC 3500 6.7L Manual Transmission 50 State
55300434AX (or higher) = DC 3500 6.7L Automatic Transmission 50 State
If the vehicle in question is a 2008 model year vehicle, then compare the current PCM software level part number to one of the following part numbers (or with a higher suffix):
61300430AK (or higher) = DC 3500 6.7L Manual Transmission 50 State
61300434AK (or higher) = DC 3500 6.7L Automatic Transmission 50 State
61301430AK (or higher) = DM 4500/5500 6.7L Manual Transmission 50 State
61301434AK (or higher) = DM 4500/5500 6.7L Automatic Transmission 50 State
If the vehicle in question is a 2009 model year vehicle, then compare the current PCM software level part number to one of the following part numbers (or with a higher suffix):
71300430AH (or higher) = DC 3500 6.7L Manual Transmission 50 State
71300434AH (or higher) = DC 3500 6.7L Automatic Transmission 50 State
71301430AH (or higher) = DM 4500/5500 6.7L Manual Transmission 50 State
71301434AH (or higher) = DM 4500/5500 6.7L Automatic Transmission 50 State
Determine if the current CCN module level software part number is one of the following (or with a higher suffix):
05172187AH (or higher) = 2007 DC (3500) / DM (3500/4500)
05172334AG (or higher) = 2008 DC (3500) / DM (3500/4500)
05172529AG (or higher) = 2009 DC (3500) / DM (3500/4500)
