## NHTSA's summary

Flash: Powertrain Control Module \(PCM\) Updates Customers must experience a Malfunction Indicator Lamp \(MIL\) illumination and the vehicle must exhibit/set one or more of the following Diagnostic Trouble Codes \(DTCs\): ● P0072\-00 \- Ambient Air Temperature Sensor Circuit "A" Low. ● P0087\-00 \- Fuel Rail Pressure Too Low. ● P2540\-00 \- Low Pressure Fuel System Sensor Circuit Range/Performance. ● P2543\-00 \- Low Pressure Fuel System Sensor Circuit Intermittent. ● P20EE\-00 \- SCR Nox Catalyst Efficiency Below Threshold \- Bank 1 Catalyst 1. ● P203F\-00 \- Reductant Level Too Low. ● P2698\-00 \- Exhaust Aftertreatment Fuel Injector "A" Performance. ● P06B9\-00 \- Cylinder 1 Glow Plug Circuit Performance. ● P06BA\-00 \- Cylinder 2 Glow Plug Circuit Performance. ● P06BB\-00 \- Cylinder 3 Glow Plug Circuit Performance. ● P06BC\-00 \- Cylinder 4 Glow Plug Circuit Performance. ● P06BD\-00 \- Cylinder 5 Glow Plug Circuit Performance. ● P06BE\-00 \- Cylinder 6 Glow Plug Circuit Performance. Customers may also comment on one or more of the following: ● Diesel Exhaust Fluid \(DEF\) level gauge inaccuracy. ● Poor cold start performance. ● Unable to initiate manual Diesel Particulate Filter \(DPF\) regen through Electronic Vehicle Information Center \(EVIC\). ● While using the remote Power Take\-Off \(PTO\) feature, the PTO may not engage or resume operation properly, after disengaging: 1. Engine is running with PTO engaged. 2. Operator is using the equipment, for example a bucket attachment. 3. Operator gets in position, then uses remote start/stop button to turn truck off while they perform a task. 4. The task is completed, then operator is ready to move the bucket so they use remote start/stop to start the engine. 5. The engine starts, but PTO does not automatically re\-engage so their equipment doesn’t operate. This bulletin involves inspecting and possibly reprogramming the PCM with the latest available software.
