The "Vehicle Speed Cal (J1939 - Trans)" is used when the ECM is configured to use the speed of the transmission output shaft in order to calculate vehicle speed. The "Vehicle Speed Input" parameter must be programmed to "Vehicle Speed Cal J1939 - Trans". This value represents the revolution of the transmission output shaft as revolutions per kilometer (revolutions per mile). This parameter must be programmed. If this parameter is not programmed, a 630-2 code is activated. This parameter affects the cruise control and the ECM speedometer signal. Also, this parameter can affect the PTO operation, extended idle and trip totals.

65000 revolutions per mile    "Vehicle Speed Cal (J1939 - ABS)"
The "Vehicle Speed Cal (J1939 - ABS)" is used to calculate vehicle speed by using the input from the wheel speed. The data from the wheel speed is transmitted via the J1939 data link. The "Vehicle Speed Input" parameter must be programmed to "Vehicle Speed Cal J1939 - ABS". The manufacturer of the ABS must transmit tire revolutions per mile that is based on the tire size. If the tire size is changed from the tire size that is programmed in the ABS the "Vehicle Speed Cal (J1939 - ABS)" must be changed.The value of this parameter is a ratio. If the actual tire size is equal to the tire size that is programmed in the ABS, the "Vehicle Speed Cal (J1939 - ABS)" parameter will be "1". Determine the ratio by dividing the tire revolutions per mile that is transmitted by the ABS by the actual tire revolutions per mile. Contact the manufacturer of the ABS in order to verify that this message is supported.If the "Vehicle Speed Input" parameter is programmed to "Vehicle Speed Cal J1939 - ABS", this parameter must be programmed. If this parameter is not programmed, a 630-2 code is activated. This parameter affects the cruise control and the ECM speedometer signal. Also, this parameter can affect the PTO operation, extended idle and trip totals.

The "Vehicle Speed Limit" (VSL) is the maximum vehicle speed that is allowed by the ECM. The ECM disables fuel flow above this speed. An inexperienced driver may think that something is wrong with the engine because the ECM does not fuel the engine above this vehicle speed limit. Vehicle speed limiting allows the implementation of a gear fast/run slow specification for the truck. The gear fast/run slow specification for the truck improves fuel economy while the parameter for the vehicle speed limit limits the maximum vehicle speed of the truck.Note: The driver reward can be used to automatically adjust the VSL according to the driver's operating techniques.

121 km/h (75 mph)

204 km/h (127 mph)    "VSL Protection"
The "VSL Protection" is the maximum engine rpm when there is a problem with the vehicle speed signal that is detected by the ECM. The ECM limits the engine speed to the value of this parameter when the ECM senses no vehicle speed signal, and a load on the engine. This feature prevents tampering by limiting engine speed if the ECM does not detect a valid vehicle speed signal.Note: When this parameter is programmed to the programmed TEL rpm, the ECM disables the 84-19 and 84-10 codes and the "VSL Protection" may be exceeded by disconnecting the vehicle speed sensor.

1700 rpm     1000 rpm     TEL rpm    "Tachometer Calibration"
The ECM uses the value of this parameter in order to translate the engine speed signal into revolutions per minute for a tachometer. The "Tachometer Calibration" is programmed in pulses per revolution (PPR). The programmable range is from 2.0 PPR to 500.0 PPR in 0.1 PPR increments.

134.0 PPR     2.0 PPR     500.0 PPR    "Speedometer Output Pulse Rate"
The ECM uses the value of this parameter in order to translate the vehicle speed signal into a signal for a speedometer. This parameter is programmed in pulses per mile. The programmable options are 4000 or 30000.

30000     4000    "Soft Vehicle Speed Limit"
This parameter operates in conjunction with the "Vehicle Speed Limit" parameter. The "Soft Vehicle Speed Limit" limits the vehicle speed within the following range:
The minimum value is 4 km/h (2.5 mph) below the programmed "Vehicle Speed Limit" at full load.
The maximum value is 4 km/h (2.5 mph) above the selected "Vehicle Speed Limit" at no load.
