0333183 EVINRUDE ORIFICE, No. 35

The alert indicators for the controller and/or the monitor are illuminated, when the engine/pump control detects a diagnostic code in the normal mode. The Real Time Error function of the "Data Mode" is used in order to show the detected diagnostic codes. The following troubleshooting procedures were written in order to help troubleshoot the system. However, the same procedures may be used to help determine the areas that may have caused an error to be logged.Note: When a diagnostic code for a sensor is present, the corresponding alert indicator on the monitor panel is activated. For example, if the coolant temperature sensor is shorted to +battery, then the following conditions will result:
The corresponding error code is stored in memory.
The gauge for the engine coolant temperature shows the region with the problem.
The action lamp will FLASH. Item 2 and item 3 are identical to the warning indications that are activated if the engine actually overheats. Troubleshooting Procedures

Example Of A Checking Procedure For The Electronic Control System (1) Preparations. (2) Problem description. (3) Error code character display (Ch. D.) (4) Check item. (5) Probable causes and solutions.Note: The character display on the monitor panel will indicate an error code on the character display (3). The charts that follow should be used in order to troubleshoot the problems that are indicated by the error code on the character display (3) .A check of a connector will provide information about the connectors that should be checked before troubleshooting. Check the specified connectors for improper connections. A loose contact between two connectors can be caused by water in the connectors.Check the connectors before troubleshooting.Preparations (1) provide information on the preliminary arrangements that must be made before troubleshooting. The problem description (2) will indicate the problems that are shown by the character display on the monitor panel.The error code that is shown will indicate specific codes for real time errors and error log. The service program that is selected will determine the pattern of the character display.The section for "check items" (4) will list items that must be checked by using a multimeter.
The "check items" (4) information, "0 Ohms" means that "continuity is present" and "infinite" means that "there is no continuity".
Connector check : (other than "[/em/]"): 0 OhmsNote: (Other than "[/em/]" means all of the terminals or all the pins of the connector, except the one that is specified in "[ ]".The following information is an exampl
