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 beside the engine or in the cab of a truck, to allow use during vehicle operation.Use the following procedures to connect the service tool to the engine.1. Turn ignition key to the OFF position.2. The Service Tool should be connected to the 3176B, C-10, C-12, and 3406E system through the Cab Data Link connector. Determine the necessary Adapter Harness Assembly (8-Pin Amp Connector 7X1403, 6-Pin Deutsch Connector 7X1686) from the 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 Service Tool.4. Turn 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 ECM, refer to "PB-23: ATA (SAE J1587/1708) Data Link Circuit Test" on page 209. 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 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 ratings 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 ratings 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
Code which prevents use of incorrect personality module for this engine. Each power 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 run at low idle and a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will also 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
Should be programmed to match the engine serial number stamped on the ratings 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 its metric (kilometers, km/h, liters) units counterpart. 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 Name Changes
Many of the parameter names have changed. The new names are listed first followed by the old name in parentheses. Some of the parameters have changed names to reflect industry descriptions, others have changed to reflect changes in the parameter itself.Customer Parameter Lockout
This parameter is available 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.This parameter is available in JAN95 or later Personality Modules.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* VSL Protection* Vehicle Speed Calibration* High Cruise Control Speed Set Limit* Top Engine Limit* Soft Vehicle Speed Limit* A/C Pressure Switch Fan-On Time* Multi-Function Output #2 (NOV95 and later Personality Modules)* Multi-Function Output #3 (NOV95 and later Personality Modules)* Multi-Function Output #4 (AUG96 and later Personality Modules)* Engine Retarder Delay (AUG96 and later Personality Modules)* Top Gear Ratio (AUG96 and later Personality Modules)* Top Gear Minus One Ratio (AUG96 and later Personality Modules)* Top Gear Minus Two Ratio (AUG96 and later Personality Modules)* Transmission Style (AUG96 and later Personality Modules)When an
