## Other bulletins for the same vehicles and component

- [0804616](/bulletins/10224659.md), 2022-10-24, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. This Bulletin involves updating the \(ASCM\) software.
- [08\-008\-14](/bulletins/10218817.md), 2022-08-29, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.; UNKNOWN OR OTHER. RA2 RG2 Or RJ2 Radio Update To Prevent Display Screen Lockup This bulletin involves updating the radio's software or replacing the radio if required. A customer may experience the radio display screen is locked on the Ram logo. This software update is to prevent this condition from occurring. Vehicles equipped with satellite radio \(sales code RSD\) may have a condition were the radio may reset a few times during a drive cycle. This condition is very intermittent.

- [18\-096\-16](/bulletins/10217742.md), 2022-08-15, Service bulletin: POWER TRAIN; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT. Flash: 6.4L Diagnostic And System Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module \(PCM\) with new software. NOTE: \*\*This bulletin contains optional software update that should only be used in situations where the customer is specifically complaining of a Drone Noise, Shudder, Pulsation, or Vibration under light throttle applications while vehicle is operating in MDS/ECO mode. There will be two separate software options displayed on the wiTECH flash tab. The software file released for this condition contains the verbiage ?OPTIONAL?. The other file is the standard software that does not contain improvements for the Drone/Shudder concern. If for some reason the customer finds this shudder improvement objectionable, the PCM software may be returned/reflashed to the standard version. Both software versions will address the remaining conditions noted in the bulletin. A small number of customers may experience a surge, shudder or pulsation type sensation when driving on smooth road surfaces at highway speeds of 64\-129 km/h \(40\-80 mph\).\*\* During normal diagnostics a technician may find one or more of the following Diagnostic Trouble Codes \(DTCs\) present: · \*\*P0335 \- Crankshaft Position Sensor Circuit.\*\* · P0300 \- Multiple Cylinder Misfire, cold Idle misfire \(DJ,D2 or DD vehicles only\). · P030X \- Cylinder Misfire \(any cylinder\). · P04D1 \- Cooled EGR Temperature Sensor Circuit High. · P04D0 \- Cooled EGR Temperature Sensor Circuit Low. · P2504 \- Charging System Output High. · P0441 \- Evap Purge System Performance. · P2066 \- Fuel Level Sensor 2 Performance. · P0401 \- EGR System Performance \(DJ/D2 vehicles only\). · P2096 \- Downstream Fuel Trim System 1 Lean \(DD/DP vehicles only\). · P2098 \- Downstream Fuel Trim System 2 Lean \(DD/DP vehicles only\). ·
