40007106 Mercury SCREW, COVER NON OIL INJECTION

Connecting ECAP Or DDT To 3176 System:
The Electronic Control Analyzer and Programmer (ECAP) and Digital Diagnostic Tool (DDT) use 12 volt DC power from the vehicle battery. This permits operation either beside the engine or in the cab of the truck during a road test.Use the following procedures to connect the service tool to the engine:A. Turn key OFF.B. The ECAP or DDT is connected to the 3176 System at the 9-Pin, Power/Data Link Connector (J8/P8), or at the optional 9-Pin Dash Data Link Connector (J12). Install the 8T5275 'T' Harness on one of the connectors (only one side of the 'T' harness connector cable is used on J12).C. Connect the other end of the 'T' Harness to the ECAP/DDT.D. Turn key ON to begin testing. The ECAP/DDT will operate with the engine running, or on truck battery power only. If the ECAP/DDT does not communicate with the 3176 System, refer to, P-120: ECAP/DDT Will Not Communicate With 3176 System.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. Correct values for these parameters are stamped on the Engine Information Plate located on the valve cover. Factory Passwords are required to change these parameters.Full Load Setting:
Number representing fuel system adjustments made at the factory to "fine tune" the fuel system. Correct value for this parameter is stamped on the Engine Information Plate for each engine.Full Torque Setting:
Similar to Full Load Setting.Personality Module Code:
Code which prevents use of wrong 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 (Check Customer Or System Parameters) will be generated and the engine will only idle. When rerating the engine 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 module is of a different family, the engine is in effect being rerated-pistons, injectors, turbocharger, etc. may also need to be changed and the Engine Information Plate should be changed to reflect the new engine rating.Engine Serial Number:
Should be programmed to match the engine serial number stamped on the Engine Information Plate and the Engine Serial Number 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 uninformed driver does not expect. These parameters may lead to power and/or performance complaints, even when the engine is operating to specifications.For detailed instructions on how to program the 3176 Diesel Truck Engine for optimum performance and fuel economy, refer to Form LEKT8587, Developing Parameters For The 3176 Diesel Truck Engine. 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. A split chart can also be plotted showing gear shift points.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. If a feature is not used, the parameter should be programmed to the default value.Vehicle Speed Parameters
Vehicle Speed Calibration:
Used by the ECM to scale the Vehicle Speed Signal reading into miles per hour. It is programmed in pulses per mile. For more information, refer to P-304: Vehicle Speed Calibration, in this manual.Vehicle Speed Limit:
Top vehicle speed the ECM will permit with load. The ECM will shut fuel off above this speed.Minimum ... 30 mphMaximum ... 127 mphDefault ... 127 mphEngine RPM At Vehicle Speed Limit (VSL):
Highest rpm that engine will turn at programmed Vehicle Speed Limit. The ECM will limit to this rpm only when it sees no vehicle speed signal and the engine is loaded.Minimum ... 1300 rpmMaximum ... 3000 rpmDefault ... 3000 rpm When this parameter is programmed to 3,000 rpm, Diagnostic Codes 31 and 36 are disabled and VSL can be exceeded by disconnecting the Vehicle Speed Sensor.Cruise Control Parameters
Low Cruise Limit:
Lowest speed (mph) at which cruise can be engaged.Minimum ... 15 mphMaximum ... 127 mphDefault ... 127 mphHigh Cruise Limit:
Highest speed (mph) at which cruise can be engaged.Minimum ... 30 mphMaximum ... 127 mphDefault ... 127 mphEngine Retarder Mode:
Defines operation of "Retarder Enable" signal while in cruise mode. Allowable options are: COAST or LATCH. When programmed to COAST, the retarder is enabled only while the service brakes are being applied. When programmed to LATCH, the retarder stays enabled after the service brakes are released (a quick press of the brake pedal latches the retarder ON). Refer to P-227: Retarder Enable Signal Test for more detail on operation of the Retarder Enable Signal TestPTO Parameters
PTO Mode Speed Limit:
Maximum mph for PTO mode.Minimum ... 1 mphMaximum ... 15 mphDefault ... 15 mphPTO Mode RPM Limit:
Maximum engine rpm in PTO mode.Minimum ... 600 rpmMaximum ... 3000 rpmDefault ... 3000 rpmProgressive Shifting Parameters
