Customer Specified Parameters
Customer Specified Parameters allow a customer to restrict how a operator operates the vehicle. Some parameters may affect engine operation in ways that the uninformed operator does not expect. These parameters may lead to power and/or performance complaints, even when the engine is operating to specifications. If the NEXG4512 Customer Parameter Configuration Aid, Service Program Module (Optional Electronic Service Tool) is installed in an ECAP equipped with the 8C9700 Rechargeable Portable Printer, a list of Customer Specified Parameters can be read from the ECM and printed out.Customer parameters may be changed repeatedly as a customer changes his operation. Customer Passwords are required to change these parameters.The following is a brief description of the Customer Specified Parameters. Along with each, are the minimum and maximum values for the parameter and the default value. If a feature is not used, the parameter should be programmed to the default value.Engine Parameters
Rating Number:Number of rating within the horsepower family. The personality module defines the horsepower family (such as 325 hp). This number defines which rating is used (such as 325 hp at 1900 rpm or 325 hp at 2100 rpm) within the family. Top Engine Limit (TEL):Maximum engine rpm when the engine is under load. The engine will still achieve rated rpm under no load.Minimum ... Map (Rating) DependentMaximum ... Rated rpm + 20 rpmDefault ... Rated rpm + 20 rpm Top engine limiting with the 3176 has no governor overrun (it is an isochronous setting with no droop). Low Idle RPM:Minimum engine rpm.Minimum ... 600 rpmMaximum ... 750 rpmDefault ... 700 rpm Vehicle ID:Identification of vehicle assigned by customer. Used only for customer reference; not used by the ECM.Factory Passwords
Factory Passwords are required to perform any one of these four functions:1. Program a new ECM. When an ECM is replaced, the System Configuration Parameters must be programmed into the new ECM. These parameters are protected by Factory Passwords.2. Rerate the engine to another engine family. This requires changing the Personality Module Code, which is protected by Factory Passwords.3. Read Customer Passwords. If the owner forgets his Customer Passwords, he will not be able to program Customer Specified Parameters. Using factory passwords, one can read Customer Passwords, then use those Customer Passwords to program Customer Specified Parameters.4. Clear certain diagnostic codes. Only Diagnostic Code 35 (Engine Overspeed) requires Factory Passwords to clear once it is LOGGED. Clearing certain other codes requires Customer Passwords. The majority of LOGGED diagnostic codes require no passwords to clear.Factory Passwords are controlled by Caterpillar and may only be obtained by authorized Caterpillar Dealers. Since factory passwords contain alphabetic characters, only the ECAP may perform these functions.To obtain factory passwords, proceed as if you already had the password. At some point, if factory passwords are truly needed, the ECAP will request factory passwords and will provide most of the information required to obtain the password on the ECAP screen.Customer Passwords
Customer Passwords are required to change ANY Customer Parameter. Customer Specified Parameters are those
