# Service bulletin 18\-042\-14 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10141243 - Published by NHTSA: 2018\-06\-18 - Manufacturer's number: 18\-042\-14 - Manufacturer's date: 2014\-07\-30 - NHTSA component: ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\) ## NHTSA's summary Generic Powertrain Control Module \(PCM\) Procedure This bulletin involves programming a generic PCM with software. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2014/MC-10141243-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2014/MC-10141243-0001.pdf) The document is the manufacturer's. This site does not hold it. ## Components Electrical system, Transmission and driveline, Automatic transmission, Software, Transmission control module ## Vehicles listed - 2004 to 2005 CHRYSLER PACIFICA - 2004 to 2005 CHRYSLER PT CRUISER - 2004 to 2005 CHRYSLER SEBRING CONVERTIBLE - 2004 to 2005 CHRYSLER VOYAGER - 2004 DODGE CARAVAN - 2005 DODGE CARAVAN - 2004 DODGE DAKOTA - 2004 to 2005 DODGE NEON - 2004 to 2005 JEEP GRAND CHEROKEE - 2004 to 2005 JEEP LIBERTY - 2005 JEEP WRANGLER ## Recalls for the same vehicles and component - [06V432000](/recalls/nhtsa/06V432000.md), 2006-11-09: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\) - [05V460000](/recalls/nhtsa/05V460000.md), 2005-10-06: POWER TRAIN:AUTOMATIC TRANSMISSION - [05V396000](/recalls/nhtsa/05V396000.md), 2005-09-14: POWER TRAIN:AUTOMATIC TRANSMISSION - [04V113000](/recalls/nhtsa/04V113000.md), 2004-03-04: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\) ## Other bulletins for the same vehicles and component - [18\-016\-13](/bulletins/10215810.md), 2022-07-18, Service bulletin: ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). This bulletin involves reprogramming the Powertrain Control Module with new software. The Technician may discover that P0128 \- Thermostat Rationality DTC is present. This DTC is a two trip code and is matured if a significant difference exists between the PCM predicted and actual engine coolant temperature during engine warm\-ups. The PCM calibration may improperly mature a P0128 DTC because the airflow across the coolant temperature sensor during colder ambient temperatures, 50° F \(10° C\) or below, causes the predicted coolant temperature to deviate from the actual coolant temperature. - [18\-016\-13](/bulletins/10188643.md), 2021-03-15, Service bulletin: ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\).

Customers may indicate that the ?Service 4WD? indicator in the instrument cluster is illuminated. They may also indicate that the transfer case will not shift from 4WD High, 4WD Low, and/or Neutral once the lamp is illuminated.Further investigation identifies that a Diagnostic Trouble Code C140F is stored or active in the Final Drive Control Modules \(FDCM\) Memory - [18\-016\-13](/bulletins/10063267.md), 2016-04-26, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE.
