Customer Parameter Lockout
The customer parameter lockout is available in order to restrict access to changing some of the available parameters. Locking out a parameter requires customer passwords (if used). Once a parameter is locked out, factory passwords are required to change the parameter. Also, once a parameter is locked out, factory passwords are required to unlock the parameter.If a lockable parameter is not locked out, factory passwords are not required. A locked out parameter restricts the parameter from being changed directly by the operator. This helps vehicle owners that are encountering problems with operators that are obtaining customer passwords and altering some of these parameters.A locked out parameter also provides an audit trail. The audit trail can be used to determine the following information:
Time of change
Operator during changeThe following customer parameters are available for lockout:
"Vehicle Speed Limit"
"VSL Protection"
"Vehicle Speed Calibration"
"High Cruise Control Set Speed Limit"
"Top Engine Limit"
"Soft Vehicle Speed Limit"
"A/C Switch Fan On-Time"
"Auxiliary Output 2"
"Auxiliary Output 3"
"Auxiliary Output 4"
"Engine Retarder Delay"
"Top Gear Ratio"
"Top Gear Minus One Ratio"
"Top Gear Minus Two Ratio"
"Transmission Style"When an attempt to change a locked out parameter occurs, the factory password screen will come up. If changing the parameter is required, follow the instructions on ET.Factory passwords are also required to change a parameter from a locked parameter to an unlocked parameter. If more than one parameter is locked out, and each one needs to be unlocked, one factory password is required."Selected Engine Rating"
"Rating Number"
The rating number is the selected rating within a power rating family. The personality module defines the power rating family (242 kW (325 hp)) and the personality module may contain only one or several ratings. The rating number defines the power rating that is used within the power rating family. The following list illustrates examples of the power rating:
324 kW (435 hp) at a governed engine speed of 1800 rpm
324 kW (435 hp) at a governed engine speed of 2100 rpmBoth ratings will be displayed for multi-torque applications."ECM Identification Parameters"
"Vehicle ID"
"Vehicle ID" is the identification of the vehicle that is assigned by the customer. "Vehicle ID" is used only for the customer's reference. "Vehicle ID" is not required by the ECM."Security Access Parameters"
"ECM Wireless Communication Enable"
The "ECM Wireless Communication Enable" determines if the ECM will transfer information over the data link through remote communications systems for customers.The parameter will default to no access. The parameter can only be enabled with factory passwords. This feature can only be enabled after the truck has been delivered to the customer. Refer to Troubleshooting, "System Overview" for additional information.

"Vehicle Speed Calibration"
The "Vehicle Speed Calibration" is the value that is used by the ECM in order to translate the vehicle speed signal into kilometers per hour (miles per hour). This parameter is programmed in pulses per kilometer (PPKM) or pulses per mile (PPM). This parameter must be programmed. If the "Vehicle Speed Calibration" parameter is not programmed, 253-02 Check Customer or System Parameters (56) will be active. This parameter affects the cruise control and the ECM speedometer signal. Also, this parameter can affect the PTO operation, extended idle and trip totals.

2485 PPKM (4000 PPM)    
65535 PPKM (40705 PPM)    
8696 PPKM (14000 PPM)    "Vehicle Speed Limit" (VSL)
The "Vehicle Speed Limit" (VSL) is the maximum vehicle speed that is allowed by the ECM. The ECM will shut off fuel above this speed. An inexperienced driver may think that something is wrong with the engine because the ECM will 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 incentive feature can be used to automatically adjust the VSL according to the driver's operating techniques.

Minimum     Maximum     Default    
48 km/h (30 mph)    
204 km/h (127 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 to this engine rpm when the ECM senses no vehicle speed signal, and a load on the engine. This is a feature that is used to prevent tampering by running without a vehicle speed input to the ECM.Note: When this parameter is programmed to 2120 rpm, the ECM disables 84-01 Loss Of Vehicle Speed Signal (31) and 84-10 Vehicle Speed Rate of Change (36) and the "VSL Protection" may be exceeded by disconnecting the vehicle speed sensor.
