Table 1
Manufacturer / Model     Alternatives     Default    
GM 530/540     "J1939", "NONE"     "J1/P1:62"    
GMT-560     "J1/P1:62", "NONE"     "J1939"    
Other     "J1939", "NONE"     "J1/P1:62"    "Exhaust Brake Switch"
The exhaust brake can be controlled by connecting an on/off switch into the ECM circuit for the output of the exhaust brake. The "Exhaust Brake Switch" parameter must be programmed to "NONE" if a switch is installed in the output circuit. A switch that is installed in the output circuit will disable the brake by opening the output circuit.The exhaust brake can also be controlled by connecting a switch circuit to the ECM switch input. This parameter must be programmed to "J1/P1:16", "J1939 Body Controller", "J1939 Cab Controller", or "J1939 Instrument Cluster" if a switch is connected to the ECM at the dedicated input for the exhaust brake.

Alternative     Default    
"J1/P1:16"
"J1939 Body Controller"
"J1939 Cab Controller"
"J1939 Instrument Cluster"     "NONE"    "Torque Limit Switch"
This parameter configures an input for a torque limit switch. The torque limit switch is used to limit the engine torque. This feature should only be used for temporary protection of equipment. This parameter must be programmed to J1/P1:7 or J1/P1:23 in order to enable this feature.
Table 3
Alternative     Default    
"J1/P1:7", "J1/P1:23"     "NONE"    "Ignore Brake/Clutch Switch"
This parameter configures an input for a brake/clutch disable switch. The "Ignore Brake/Clutch Switch" is used for applications that require the mobile use of the vehicle with a set engine rpm that does not require the brake or the clutch to disengage the engine rpm set speed. This parameter must be programmed to "J1/P1:47" for this feature to be enabled.
Table 4
Alternative     Default    
"J1/P1:47"     "NONE"    "Two-Speed Axle Switch"
This parameter configures an input for a two-speed axle switch. When a two-speed axle is used, the change in gear ratios from the main drive axle ratio to the two-speed axle ratio alters the calibration of the vehicle speed signal. When the parameter is programmed to "J1/P1:6" and the switch is in the ON position the ECM automatically adjusts the vehicle speed calibration. This will ensure that the ECM driven speedometer and the information that is stored in the ECM correctly reflect the actual vehicle speed.
Table 5
Alternative     Default    
"J1P1:6"     "NONE"    "Diagnostic Enable"
This parameter configures an input for a diagnostic enable switch. The diagnostic enable switch is used to retrieve diagnostic flash codes. Set this parameter to "J1/P1:46" if a switch is wired to this input. Set this parameter to "J1939 Body Controller", "J1939 Cab Controller", or "J1939 Instrument Cluster" if a J1939 message is used.
Table 6
Alternative     Default    
"J1/P1:46"
"J1939 Body Controller"
"J1939 Cab Controller"
"J1939 Instrument Cluster"     "NONE"    "PTO Engine RPM Set Speed Input A"
This parameter configures an input for a PTO engine rpm set speed A switch. This switch is used to control engine speed during PTO operation. The "PTO Configuration" parameter must be programmed to "Cab Switches", "Remote Switches" or "Remote Throttle" and the "PTO Engine RPM Set Speed A" parameter must be programmed to a valid speed.
Table 7
Alternative     Default    
"J1P1:46"     "NONE"    "PTO Engine RPM Speed Input B"
This parameter configures an input for a PTO engine rpm set speed B switch. This switch is used to control engine speed during PTO operation. The "PTO Configuration" parameter must be programmed to "Cab Switches", "Remote Switches" or "Remote Throttle" and the "PTO Engine RPM Set Speed B" parameter must be programmed to a valid speed.
Table 8
Alternatives     Default    
"J1/P1:7", "J1P1:23"     "NONE"    "PTO Engine Shutdown Switch"
This parameter configures an input to use for a PTO engine shutdown switch. The switch will shut down the engine when the engine is in PTO mode and there is no vehicle speed.

Alternatives     Default    
"J1/P1:7", "J1P1:23"     "NONE"    "Cruise Control On/Off Switch"
This parameter configures an inp
