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:
"Multi-Torque Ratio"
"Vehicle Speed Calibration"
"Vehicle Speed Cal (J1939 - Trans)"
"Vehicle Speed Cal (J1939 - ABS)"
"Vehicle Speed Limit"
"VSL Protection"
"Soft Vehicle Speed Limit"
"Low Speed Range Axle Ratio"
"High Speed Range Axle Ratio"
"Low Cruise Control Set Speed Limit"
"High Cruise Control Set Speed Limit"
"Top Engine Limit"
"Transmission Style"
"Top Gear Ratio"
"Top Gear Minus One Ratio"
"Top Gear Minus Two Ratio"
"A/C Switch Fan On-Time"
"Engine Retarder Delay"
"Engine Monitoring Lamps"
"Driver Reward Enable"
"Fan Control Type"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."Multi-Torque Ratio"
This parameter is used to select the desired Multitorque trip point. Multitorque ratings allow the engine to provide additional torque, additional horsepower, and torque when the transmission is operating in higher gear. The additional torque allows the truck to crest a hill without downshifting and increases fuel economy. The "Multi-Torque" feature also helps to reduce wear. The trip point is determined by a ratio of engine speed versus vehicle speed. The three programmable options represent the different trip point values that are listed below.
Table 1
Programmable Option    Turn On Ratio (RPM to MPH)    Gear Range    
MT-4     71.5     Top 4 Gears    
MT-2     37.6     Top 2 Gears    
MT-1     27.9     Top 1 Gear    Note: This feature is not used with standard engine ratings. This feature is only available for multitorque ratings.

"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 out of Caterpillar to no access. The parameter can only be enabled by getting 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 operat
