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 customer. 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

Customer Specified Parameters allow the vehicle

owner to influence the operating technique of

may lead to power or performance complaints

even though the engine's performance is within the

as a customer's operation changes or as new

drivers are assigned to a truck. Customer passwords

The following information is a brief description of

"High Cruise Control Speed Set Limit"

the Customer Specified Parameters. The following

parameter values are included with the descriptions:

"High Speed Range Axle Ratio"

Minimum

"Input #6" (MAR99 Personality Modules through

JUL01 Personality Modules)

Maximum

"Low Speed Range Axle Ratio"(MAR98 and

Default

newer Personality Modules)

Note: Parameter values that are shown in bold text

"Max PTO Vehicle Speed" (OCT01 and newer

are programmed settings that disable the feature.

Personality Modules)

The tables show values in an approximate range for

"Soft Vehicle Speed Limit"

metric units that is followed by the metric conversion

to English units. The exact range of the parameter

"Top Engine Limit"

in metric units depends on the service tool that is

being used. Each tool may use slightly different

"Transmission Style"

conversion factors.

Customer Parameter Lockout

The Customer Parameter Lockout is available in

"Vehicle ID"

order to restrict access to changing some of the

available parameters. Locking out a parameter

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.
