Summary

Flash: Powertrain Control Module (PCM) Updates Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find one or more of the following Diagnostic Trouble Codes (DTC)s: ? P24D1-00 - Particulate Matter Sensor Regeneration Incomplete. NOTE: This software update will help prevent P24D1-00 from setting. Refer to all applicable published service bulletins for detailed repair procedures and labor times regarding this DTC. ? P2002-00 - Diesel Particulate Filter (DPF) Efficiency based on Particulate Matter (PM) sensor monitoring. NOTE: If DTC P2002 is present it will require DPF and PM sensor replacement. Refer to all applicable published service bulletins for detailed repair procedures and labor times regarding Diesel Particulate Matter Sensor (DPM) replacement. ? P24AE-00 - Particulate Matter Sensor Circuit. ? P24B0-00 - Particulate Matter Sensor Circuit Low. ? P24B1-00 - Particulate Matter Sensor Circuit High. ? P24B2-00 - Particulate Matter Sensor Circuit Intermittent. ? P24D0-00 - Particulate Matter Sensor Supply Voltage Circuit Low. ? P24D3-00 - Particulate Matter Sensor Supply - Circuit Voltage Above Threshold. ? P24AF-00 - Particulate Matter Sensor Circuit Performance. ? P24B5-00 - Particulate Matter Sensor Heater Control Circuit Low. ? P24B6-00 - Particulate Matter Sensor Heater Control Circuit High. ? P24B7-00 - Particulate Matter Sensor Heater Resistance. ? P24DA-00 - Particulate Matter Sensor Exhaust Sample Error Bank 1. ? U05A4-00 - Particulate Matter Sensor Received Invalid Data From ECM - PCM. ? U02A3-00 - Loss of Communication with PM Sensor Module. ? P24B2-00 - Particulate Matter Sensor Circuit Intermittent. Customers may also experience the following: ? More frequent Diesel Particulate Filter (DPF) regenerations. NOTE: This software update will help reduce smoke emissions and reduce DPF regeneration events. This bulletin involves reprogramming the PCM wit
