| 18-033-25 REV. A | 2025-07-09. Service bulletin. 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): ● P0420 - Catalyst System Efficiency Below Threshold Bank 1. ● P0430 - Catalyst System Efficiency Below Threshold Bank 2. ● P0456 - EVAP System Small Leak. ● P06EF - Engine Restart Performance. ● P0175 - Fuel System 2/1 Rich. ● P258B - Electronic Vacuum Pump Performance. ● P0128 - Thermostat Rationality. ● C0062 - Longitudinal Acceleration Sensor. In addition, the customer may experience one or more of the following: ● Vehicle fails emissions inspection testing due to OBD catalyst monitor readiness. ● Engine RPM erratic and or bucking, when accelerating after slowing down. ● Occasional engine shut off while shifting from 4WD low to 2WD. ● Improvements to the vacuum pump cycle time. ● Rough idle after cold start. This bulletin involves reprogramming the PCM with the latest available software. |
