the PTO engagement. A confirmation from the PTO returns to the TCM via the “PTO Confirm” line to com

wire control and one over the J-1939 network).

vehicle systems.
• The TCM Engage circuit load shall draw no more than 0.50 amps with 16 volts applied for a 12 volt vehicle
system or 32 volts applied for a 24 volt system.
