Section 4: Troubleshooting With A Diagnostic Code alert the operator. If the condition generating the diagnostic code occurs only for a brief moment, the message will disappear from the Active Diagnostic Codes screen and the diagnostic code will be Logged in the ECM memory.
Diagnostic Codes Diagnostic codes alert the operator that a problem exists and indicate the nature of the problem to the service technician.
Logged Diagnostic Codes
Diagnostic codes consist of three parts. The MID, CID and FMI.
When the ECM generates a diagnostic code, it usually logs the code in permanent memory within the ECM. The ECM has an internal diagnostic clock and will record the number of occurrences, the hour of the first occurrence, and the hour of the last occurrence of the code. These will be indicated on the ET Logged Diagnostic Codes screen under the columns for "Occ.” indicating the number of occurrences, “First” indicating the diagnostic clock hour of the first occurrence, and “Last” indicating the diagnostic clock hour of the last occurrence. Knowing when and how often the code was generated can be a valuable indicator when troubleshooting intermittent problems.
The MID, or MID, or Module IDentifier IDentifier indicates which electronic module generated the diagnostic code. The ECM is MID=36 ($24). The CID, CID, or Component IDentifier, IDentifier, indicates which component in the system the diagnostic code is for. The FMI, FMI, or Failure Mode Identifier indicates what the failure mode is. Refer to Diagnostic Terminology later in this section for additional details. Diagnostic codes may be viewed on a PC running Electronic Technician (ET). On some Electronic Service Tools or display modules, the MID is not displayed because it is obvious which module you are reading the diagnostic codes from.
ET can retrieve and delete Logged codes. Any Logged diagnostic codes will automatically be deleted if no additional occurrences are recorded in 100 hours. When investigating logged diagnostic codes, keep in mind the following information.
To troubleshoot a diagnostic code, refer to the Quick Reference Sheet For ECM Diagnostic Codes in Codes in this section under the specific code number. The code number will direct you to a procedure in Section 5: Functional Tests.
•
Do not confuse diagnostic codes with event codes (refer to Active Events and Logged Events in this section). Events can be active/logged in the ECM to track information about the engine. An example would be a low oil pressure event. An event is generated when the engine oil pressure is low but not out of range for the sensor. This does not indicate not indicate a problem with the sensor, rather it indicates a problem with the engine oil pressure. Refer to Active Events and Logged Events later in this section for more information. Active Diagnostic Codes An Active diagnostic code represents a problem with the electronic control system that should be investigated and corrected as soon as possible. possible.
•
To troubleshoot a Logged diagnostic code, refer to the Quick Reference Sheet For Diagnostic Codes in this section. The code number will direct you to a procedure in Section 5: Functional Tests. If Tests. If the symptoms continue, use the proper procedure for troubleshooting the symptoms that have been experienced by the operator. Refer to Section 7: Troubleshooting Without a Diagnostic Code Or Event Code. Code. NOTE: Always NOTE: Always clear logged diagnostic codes after investigating and correcting the problem which generated the code.
When an Active Diagnostic Code is generated, the Active Alarm warning indicator (Engine Control Alarm Status parameter on ET Status screen) is activated to G3516B Engine (Preliminary 12APR02)
•
Some diagnostic codes may be easily triggered and do not result in operator complaints. If the time the code was logged does not relate to a complaint, there may be nothing to fix. The most likely cause of an intermittent problem is a faulty connection or damaged wiring. Next likely is a component failure (sensor or switch). Least likely is failure of the ECM itself. Diagnostic codes that are logged repeatedly may indicate a problem that needs special investigation.

Active Events The ECM can indicate active events. Events refer to engine operating conditions such as low oil pressure or high engine coolant temperature. Active Events do not indicate an electronic system problem, but may indicate an engine system problem. The example diagram shown indicates the output voltage from an Oil Temperature Sensor and how the ECM responds to that voltage.

When an Active Event Code is generated, the Active Alarm warning indicator (Engine Control Alarm Status parameter on ET Status screen) is activated to alert the operator. If the condition generating the Event Code occurs only for a brief moment, the message will disappear from the Active Event Codes screen and the event code will become a Logged Event Code in the ECM memory. NOTE: The Active Event Codes are listed in ascending numerical order with the lowest event code displayed at the top of the list.
Engine is too hot, but there is not an electronic problem
NORMAL ENGINE OIL OPERATING TEMPERATURE RANGE
Refer to Section 3: Troubleshooting With an Event Code. Logged Events The ECM can log events. Events refer to engine operating conditions such as low oil pressure or high engine coolant temperature. Logged Events do not indicate an electronic system problem, but may indicate an engine system problem. The example diagram shown indicates the output voltage from a Oil Temperature Sensor and how the ECM responds to that voltage.
0.2V Sensor Diagnostic Generated (Electronic Problem)
When the ECM generates an Event Code, it always logs the code in permanent memory within the ECM. The ECM has an internal diagnostic clock and will record the number of occurrences, the hour of the first occurrence, and the hour of the last occurrence of the code. These will be indicated on the ET Logged Event Codes screen under the columns for "Occ. ” indicating the number of occurrences, “First” indicating the diagnostic clock hour of the first occurrence, and “Last” indicating the diagnostic clock hour of the last occurrence. Knowing when and how often the code was generated can be a valuable indicator when troubleshooting intermittent problems. NOTE: The Logged Event Codes are listed in chronological order with the latest ( ”Last”) event code displayed at the top of the list.

Diagnostic Terminology Module Identifier (MID) - Two or three digit code which is assigned to each module or control system. Module ID (Hex) - Description 36 ($24) - Gas Engine Control Module (ECM) 111 ($6F) - Integrated Temperature Sensing Module (ITSM) 97 ($61) - Customer Communication Module (CCM) Component Identifier (CID) -
Two or three digit code which is assigned to each component or system.
Failure Mode Identifier (FMI) - Type of failure the component experienced (adopted from SAE standard practice J1587 diagnostics).

Active Code - The CID and FMI can be viewed on the ET Active Diagnostic Codes Screen. Logged Code - The diagnostic will be entered into the permanent memory (Logged Diagnostics) when it becomes Active. The number of occurrences will be saved in the good to bad counter in the permanent memory (Logged Diagnostics). First and last occurrence time (Diagnostic Clock Hours) will also be saved in the permanent memory (Logged Diagnostics). This information is then available for displa y on the ET Logged Diagnostic Codes Screen.
