SPN 1484 FMI 13 – J1939 Message was lost (CRC error) Fault Code (Symptoms, Causes & Fix)

The SPN 1484 FMI 13 fault code indicates a communication issue within the J1939 network, specifically a CRC error, which means a message was lost or corrupted during transmission. This diesel engine fault code often points to problems with the wiring harness, connectors, or network components that facilitate communication between the engine control module (ECM) and other electronic modules.What SP read more

SPN 1484 FMI 9 – J1939 Message was lost (message counter error) Fault Code (Symptoms, Causes & Fix)

The SPN 1484 FMI 9 fault code indicates a communication issue within the J1939 CAN bus network of a diesel engine. Specifically, this diagnostic trouble code (DTC) signals that a J1939 message was lost due to a message counter error. This means the Engine Control Module (ECM) detected an interruption or loss of expected data packets from one or more modules on the network. What SPN 1484 FMI 9 Mea read more

SPN 1482 FMI 9 – J1939 TC1 Message (Transmission Mode) is missing Fault Code (Symptoms, Causes & Fix)

The SPN 1482 FMI 9 fault code indicates that the J1939 TC1 Message, which communicates the transmission mode, is missing. This diesel engine fault code suggests a disruption in the communication between the Transmission Control Module (TCM) and the Engine Control Module (ECM), potentially affecting the transmission's operation.

SPN 1328 FMI 10 – Cylinder #6 Misfire Rate Above 5% Detected Fault Code (Symptoms, Causes & Fix)

The SPN 1328 FMI 10 fault code is a diesel engine diagnostic trouble code indicating that the misfire rate for cylinder #6 has exceeded 5%. This code is triggered when the Engine Control Module (ECM) detects an abnormal combustion event in cylinder #6, often due to fuel delivery or mechanical issues.What SPN 1328 FMI 10 MeansThe SPN 1328 FMI 10 fault code specifically relates to a misfire conditio read more

SPN 1327 FMI 31 – Idle Smoothness Control / Cylinder #5 Quantity Deficit at Idle Fault Code (Symptoms, Causes & Fix)

The SPN 1327 FMI 31 fault code is a diesel engine diagnostic trouble code indicating an issue with the idle smoothness control, specifically a quantity deficit at idle for Cylinder #5. This code suggests that the Engine Control Module (ECM) has detected an imbalance in the fuel delivery to Cylinder #5, which can affect engine performance and smoothness at idle.What SPN 1327 FMI 31 MeansThe SPN 132 read more

SPN 1327 FMI 10 – Cylinder #5 Misfire Rate Above 5% Detected Fault Code (Symptoms, Causes & Fix)

The SPN 1327 FMI 10 fault code indicates that the Engine Control Module (ECM) has detected a misfire rate above 5% in cylinder #5. This diesel engine fault code suggests that the combustion process in cylinder #5 is not occurring as expected, potentially leading to performance issues.What SPN 1327 FMI 10 MeansWhen the SPN 1327 FMI 10 fault code is active, it means the ECM has identified an irregul read more

SPN 1326 FMI 31 – Idle Smoothness Control / Cylinder #4 Quantity Deficit at Idle Fault Code (Symptoms, Causes & Fix)

The SPN 1326 FMI 31 fault code indicates an issue with the idle smoothness control, specifically a quantity deficit at idle for Cylinder #4. This diesel engine fault code suggests that the Engine Control Module (ECM) has detected an imbalance in the fuel delivery to Cylinder #4, which can affect engine performance and smoothness at idle.What SPN 1326 FMI 31 MeansSPN 1326 FMI 31 is a diagnostic tro read more

SPN 1326 FMI 10 – Cylinder #4 Misfire Rate Above 5% Detected Fault Code (Symptoms, Causes & Fix)

The SPN 1326 FMI 10 fault code indicates that the engine control module (ECM) has detected a misfire rate above 5% in cylinder #4. This diesel engine fault code suggests an issue with the combustion process in the specified cylinder, which could be due to various mechanical or electrical problems.What SPN 1326 FMI 10 MeansSPN 1326 FMI 10 represents a misfire in cylinder #4, where the ECM identifie read more

SPN 1325 FMI 31 – Idle Smoothness Control / Cylinder #3 Quantity Deficit at Idle Fault Code (Symptoms, Causes & Fix)

The SPN 1325 FMI 31 fault code is a diesel engine fault code indicating an issue with idle smoothness control, specifically a quantity deficit in Cylinder #3 at idle. This diagnostic trouble code suggests that the engine control module (ECM) has detected a discrepancy in the fuel delivery or combustion process for Cylinder #3, which can affect engine performance and idle quality.
