Connecting an Electronic Service Tool
The Electronic Control Analyzer Programmer (ECAP) and the Communications Adapter are powered by 12 volts DC from the vehicle battery. This permits operation near the engine compartment or in the cab of a truck, to obtain readings during vehicle operation. Use the following procedure to connect the service tool to the engine.1. Turn the ignition key to the OFF position.2. The Electronic Service Tool should be connected to the 3100 HEUI system through the Cab Data Link connector. Determine the necessary Adapter Harness Assembly from the service tool list for the vehicle you are working with. Connect the appropriate adapter to the 8T5275 (or 139-4166) Breakout T harness connector cable.3. Connect the opposite end of the Breakout T cable to the Electronic Service Tool.4. Turn the ignition key to the ON position to begin testing. The Service Tool will operate with the engine running, or with the engine OFF, ignition key ON. If the Tool does not communicate with the 3100 HEUI ECM, refer to "PB-21: ATA (SAE J1587/1708) Data Link Circuit Test" on page 148. The Service Tool may restart during engine cranking due to a voltage dip on the battery line.System Configuration Parameters
System Configuration Parameters affect emissions or rated power of the engine. They are programmed at the factory and would normally never need to be changed through the life of the engine. System Configuration Parameters must be reprogrammed if an ECM is replaced, but not if the Personality Module is replaced (unless the engine rating changes). Proper values for these parameters are stamped on the Engine Information Plate, located on the valve cover or intake manifold. Factory Passwords are required to change these parameters. The following is a description of the System Configuration Parameters.Full Load Setting
Number representing fuel system adjustment made at the factory to "fine tune" the fuel system. The correct value for this parameter is stamped on the Engine Information Plate. A new ECM must have this parameter programmed to avoid generating a Diagnostic Code 253-02 Check Customer Or System Parameters (56).Full Torque Setting
Similar to Full Load Setting. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.Personality Module Code
This code prevents use of incorrect personality module for this engine. Each power rating family and emission certification has a different code associated with it. When a personality module is replaced (either using a personality module chip or if flash programmed), this code (stored in the ECM) must match the one in the introduced personality module or the engine will only operate at low idle and a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.When rerating the engine, programming this code to "0" will prompt the ECM to read and match its stored code to the Personality Module Code. This code does not need to be programmed when a personality module is replaced, as long as the new module is of the same family and emission year.If the Personality Module is of a different family, then pistons, injectors, etc may need to be changed and the Engine Information Plate must also be changed to reflect the new rating.Some vehicle systems, such as the cooling system or transmission may also require changes when uprating an engine. Please contact the local OEM dealer for further information.Engine Serial Number
This number should be programmed to match the engine serial number stamped on the Engine Information Plate. A new ECM is delivered with the engine serial number programmed to 0XX00000.Customer Specified Parameters
Customer Specified Parameters allow the truck owner to influence how a driver operates the vehicle. Some parameters may affect engine operation in ways an inadequately trained driver does not expect. These parameters may lead to power or performance complaints, even when the engine is performing to specification.Customer parameters may be changed repeatedly as a customer changes his operation or as new drivers are assigned to a truck. 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. Parameter value shown in bold is programmed setting to disable a feature.The tables show values in U.S. (or English) units (miles, mph, quarts), followed by an approximate range for metric (kilometers, km/h, liters) units. The exact range of the parameter in metric units depends upon the Service Tool used because each Tool may use slightly different conversion factors. Customer Parameter Lockout - 3126 OnlyThis parameter is available in JUN97 and Later Personality Modules to restrict access to changing some 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 or 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 customer. This helps vehicle owners encountering problems with operators obtaining Customer Passwords and altering some of these parameters.It also provides a trail to determine who changed the parameter and when. The following Customer Parameters are available for Lockout.* Vehicle Speed Limit* Vehicle Speed Limit Protection* Vehicle Speed Calibration* High Cruise Control Speed Set Limit* Soft Vehicle Speed Limit* Transmission StyleWhen an attempt to change a locked out parameter occurs, the Factory Password screen will come up. Follow the instructions on the Service Tool screen if changing the parameter is required.Factory Passwords are also required to change a parameter from "locked" to "unlocked". If more than one parameter is locked out, and each one needs to be unlocked, one Factory Password is required. Engine Power Rating Selection NumberRating number within a power family. The Personality Module defines the power family such as 300 hp (224 kW) and may contain only one or several ratings. The rating number defines which rating is used within the family. Vehicle IDIdentification of the vehicle assigned by the customer and used only
