Connecting ECAP or DDT to PEEC III
1This is a subscription, since it is anticipated that it will be changin g at regular intervals.The Electronic Control Analyzer Programmer (ECAP) and Digital Diagnostic Tool (DDT) are powered by the 12 volts DC from the vehicle battery. This permits operation on the ground or in the cab of a truck, which allows taking readings during vehicle operation. Use the following procedures to connect the service tool to the engine:A. The ECAP or DDT may be connected to the PEEC III system at J8, the 9-pin, gray plastic, Deutsch brand connector labeled Engine Data Link Connector. Only one side of the "T" harness connector cable is used. Remove the cap on J8 and replace once testing has been completed.B. Connect the opposite end of the "T" cable to the ECAP or DDT.C. The ECAP or DDT will operate with the engine running, or with the engine off, key on. If the ECAP or DDT does not communicate with PEEC III, refer to P312; ECAP/DDT will not communicate with PEEC III.System Configuration Parameters
System Configuration Parameters are those that affect emissions or horsepower of the engine. They are programmed at the factory and would normally never need to be changed through the life of the engine. 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. Figure 1. on page 20 is an example of the ECAP screen displaying System Configuration Parameters. The following is a brief description of the System Configuration Parameters:Full Load Setting:
Number representing fuel system adjustment made at the factory to "fine tune" the fuel system. Correct value for this parameter is stamped on the engine information ratings plate.Full Torque Setting:
Similar to Full Load Setting.Personality Module Code:
Code which prevents use of incorrect personality module for this engine. Each horsepower family and emission certification has a different code associated with it. This code (stored in ECM) MUST match that in the personality module or a Diagnostic Code 56 will be generated and the engine will only run at low idle. When rerating or installing a new ECM, programming this code to "0" will prompt the ECM to read and match its stored code to the personality module. Note that 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. If the PM is of a different family, then pistons, nozzles, etc. may need to be changed and the engine information plate should also be changed to reflect the rerate.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 a customer to restrict how a driver operates the vehicle. Some parameters may affect engine operation in ways that the inadequately trained driver does not
