This code is triggered when the calculated soot level in the Diesel Particulate Filter (DPF) is moderately higher than expected. This condition indicates a significant accumulation of soot that requires prompt attention to prevent further escalation.

This diagnostic trouble code indicates that the calculated soot level in the Diesel Particulate Filter (DPF) is slightly higher than expected. While not immediately critical, this condition suggests that the DPF is accumulating soot at a rate that requires attention to prevent further buildup.

This diagnostic code is triggered when the calculated soot level in the Diesel Particulate Filter (DPF) is extremely high. Excessive soot buildup can impede exhaust flow and significantly impact the effectiveness of the aftertreatment system.

READ MORE

This code is set when the ECU detects that the number of DPF recovery attempts without a successful active regeneration has exceeded the limit. This situation can arise due to repeated failures in initiating or completing DPF regeneration cycles.

This diagnostic trouble code is triggered when the ECU detects that the rate of change in the Diesel Particulate Filter (DPF) soot load is higher than expected. This can indicate issues with combustion efficiency, fuel quality, or aftertreatment system operation.

This diagnostic trouble code is triggered when the calculated soot level in the Diesel Particulate Filter (DPF) is determined to be extremely high. Excessive soot accumulation can impede exhaust flow and reduce the effectiveness of the aftertreatment system.

READ MORE

This code is set when active regeneration of the Diesel Particulate Filter (DPF) is inhibited due to the exhaust gas temperature being too low. The target temperature for the Diesel Oxidation Catalyst (DOC) inlet was not achieved during the exhaust temperature management process.

READ MORE

This diagnostic trouble code indicates that active regeneration of the Diesel Particulate Filter (DPF) has been inhibited due to low exhaust gas temperature. The target value for the Diesel Oxidation Catalyst (DOC) inlet temperature was not reached during exhaust temperature management, preventing the regeneration process.

READ MORE

This diagnostic code indicates that Diesel Particulate Filter (DPF) regeneration is required due to a high calculated soot level, but the regeneration process is disabled because the inhibit switch is active. High soot levels can impact engine performance and emissions compliance.

This code indicates that the ECU has detected an extremely low high voltage supply to the fuel injectors, even though the unswitched battery voltage to the ECU is within the correct range. This issue can lead to improper fuel injection and engine performance problems.

This fault code is triggered when the DEF tank fluid level sensor detects an issue with accurately measuring the fluid level. This can lead to incorrect DEF dosing and impact the effectiveness of the aftertreatment system.
