Customer specified parameters allow the vehicle owner to influence the operating technique of a driver. Some parameters may affect engine operation in a way that would not be expected by an inadequately trained driver. These parameters may lead to power or performance complaints even though the engine's performance is within the engine's specification.Customer parameters may be changed repeatedly as a customer's operation changes or as new drivers are assigned to a truck. Customer passwords are required to change these parameters. The customer password must be programmed into the Engine Control Module (ECM).The following information is a brief description of the customer specified parameters. The following parameter values are included with the descriptions:
Minimum
Maximum
DefaultThe tables show values in an approximate range for metric units that is followed by the metric conversion to English units. The exact range of the parameter in metric units depends on the service tool that is being used. Each tool may use slightly different conversion factors.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, the parameter can not be changed until the parameter is unlocked.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:

VSL ProtectionWhen 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 the Caterpillar Electronic Technician (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
