===DTC P2458-21=== Code: P2458 - Diesel Particulate Filter Regeneration Duration Additional Fault Symptom: - Signal is Above Maximum Threshold Status: - Previously Set DTC - Not Present at Time of Request - Malfunction Indicator Lamp is Off for this DTC Module: Powertrain Control Module Diagnostic Trouble Code details Diesel Particulate Filter Regeneration Duration This DTC may be caused by : Over Charged Filter Check the following: Check that the differential pressure sensor and hoses are intact and not blocked. Check that the pre and post-catalyst temperature sensors are operating correctly. Check the air intake system for leaks, blockages and correct operation. If any of the DPF or related components are renewed, perform the DPF service functions from toolbox. Check the PCM for the latest calibration. Perform a manual regeneration of the DPF system. Re-run the test again to ensure the fault has been fixed. ===END DTC P2458-21=== ===DTC P2584-A1=== Code: P2584 - Fuel Additive Control Module MIL Request Additional Fault Symptom: - Signal is Above Maximum Threshold Status: - Previously Set DTC - Not Present at Time of Request - Malfunction Indicator Lamp is On for this DTC Module: Powertrain Control Module Diagnostic Trouble Code details Fuel Additive Control Module MIL Request ===END DTC P2584-A1=== ===DTC P2585-21=== Code: P2585 - Fuel Additive Control Module Warning Lamp Request Additional Fault Symptom: - Signal is Above Maximum Threshold Status: - Previously Set DTC - Not Present at Time of Request - Malfunction Indicator Lamp is Off for this DTC Module: Powertrain Control Module Diagnostic Trouble Code details Fuel Additive Control Module Warning Lamp Request ===END DTC P2585-21=== ===DTC P061B-21=== Code: P061B - Internal Control Module Torque Calculation Performance Additional Fault Symptom: - Signal is Above Maximum Threshold Status: - Previously Set DTC - Not Present at Time of Request - Malfunction Indicator Lamp is Off for this DTC Module: Powertrain Control Module Diagnostic Trouble Code details Internal Control Module Torque Calculation Performance This DTC is set when one or more of the following conditions occur.
