814945 Mercury SCREW, (.312-18 x 3.500), CLAMP BRACKET TO TRANSOM

Connecting an ECAP to 3176B
The Electronic Control Analyzer Programmer (ECAP) is powered by the 12/24 volts DC from the vessel batteries. This permits operation beside the engine which allows taking readings during engine operation. Use the following procedures to connect the service tool to the engine:A. Turn KEY OFF.B. The ECAP should be connected to the 3176B system through the Data Link connector. Connect the adapter to the 8T5275 "T" harness connector cable.C. Connect the opposite end of the "T" cable to the ECAP.D. Turn KEY ON to begin testing. The ECAP will operate with the engine running, or with the engine Off, key On. If the ECAP does not communicate with the engine, refer to P-514: ATA (SAE J1587/1708) Data Link Circuit Test. The ECAP may restart during engine cranking due to a voltage dip on the battery line.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. 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 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. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.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 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 253-02 Check Customer Or System Parameters (56) will be generated and the engine will only run at low idle. 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. 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 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 should also be changed to reflect the new rating. Some vessel 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 a customer to decide how a operator operates the vessel. Some parameters may affect engine operation in ways an inadequately trained operator 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 operators are assigned to a vessel. Customer Passwords are required to change these parameters. Figure 2 on page 31 is an example of the ECAP screen displaying Customer Specified 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. The parameter value shown in BOLD is the programmed setting to disable a feature.Engine Power Rating Selection Number:
Number of rating within horsepower family. The Personality Module defines the horsepower family (such as 325 hp) and may contain several ratings within that family. The rating number defines which rating is used (such as 325 hp @ 1900 rpm or 325 hp @ 2100 rpm) within the family.Vessel ID:
Identification of the vessel assigned by the customer. Used only for customer reference: not required by the ECM.Tachometer Calibration:
Used by the ECM to scale the engine speed signal into revolutions per minute for a tachometer. Programmed in pulses per revolution. The choice is either 12 OR 113 ppr. Trolling Speed:
Trolling speed can be programmed to any value from 900 to 1200 rpm. Transmission Oil Pressure:
Transmission oil pressure can be programmed to any value from 700 to 2716 kPa (100 to 388 psi). The oil pressure gauge will flash when any of the warning segments are ON. Transmission Oil Temperature:
High transmission oil temperature can be programmed to any value from 50 to 120°C (122 to 248°F). The oil temperature gauge will flash when any of the warning segments are ON. Engine Monitoring Parameters
Engine Monitoring Mode:
Determines the level of action taken by the ECM in response to a potentially engine damaging condition recognized by the Caterpillar Coolant Temperature, Oil Pressure, Intake Manifold Air Temperature, or OEM Coolant Level (if installed and enabled) Sensors. Coolant Level Sensor Enable/Disable:
Determines if the ECM monitors the Coolant Level Sensor inputs. Passwords
Factory Passwords
Factory passwords are required to perform each of the following 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 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 loses the customer passwords, they will not be able to program customer parameters. Using factory passwords, one can read customer passwords, then use those customer passwords to program customer parameters.4. Clear Certain Diagnostic Codes Only Diagnostic Code 190-00 (Engine Overspeed Warning) requires factory passwords to clear once it is
