12 Chrysler Models: 300, Town and Country, Pacifica, and More
Car Computer Exchange carries 195 Chrysler modules across 12 models, covering PCM, ECM, and TCM replacements. The Chrysler 300 leads the catalog with 42 modules spanning the 2.7L V6 through the 6.1L SRT V8. Town and Country follows at 31 modules, then PT Cruiser (24), Sebring (21), 200 (14), Concorde (12), Pacifica (10), and 300M (11). Smaller model lines include Cirrus, LHS, Aspen, and 300C.
Every module in the catalog is a remanufactured unit, tested and programmed before it ships. The catalog covers both current Chrysler production (300, Pacifica) and discontinued nameplates (PT Cruiser, Sebring, Concorde, LHS) that are still on the road and still need replacement car computers. Buyers across 4,500+ on-site reviews rate Car Computer Exchange at 4.8+ stars.
PCM vs ECM vs TCM: What Controls Your Chrysler
On a Chrysler, the powertrain control module (PCM) manages both the engine and automatic transmission. ECM (engine control module), ECU, and engine computer are different names for the same type of module. Parts catalogs, scan tools, and repair shops use all four terms interchangeably.
The TCM (transmission control module) is a separate unit that handles only transmission shifting on certain Chrysler models, including the Town and Country, Sebring, and 200. Car Computer Exchange stocks both PCM and TCM replacements for these models.
Chrysler shares its module architecture with Dodge and Jeep across the Stellantis platform. The 3.6L Pentastar V6 and 5.7L Hemi V8 PCMs use the same calibration families across all three brands, with VIN programming differentiating each vehicle.
Chrysler PCM Failure Signs from No-Start to P0601
A failing Chrysler PCM typically triggers one or more of these symptoms:
- No-start or crank-no-start with no communication on the scan tool
- Check engine light that returns after clearing codes or replacing sensors
- Erratic transmission shifting or delayed gear engagement
- Random stalling or rough idle that worsens over time
- Multiple unrelated codes firing at the same time
If a scan tool returns P0601 (Internal Control Module Memory Check Sum Error) or P0606 (PCM Processor Fault), the module itself has failed internally. These codes indicate memory or processor damage, not a sensor or wiring problem. Capacitor degradation and solder fatigue drive most Chrysler PCM internal faults across the catalog.
The Chrysler 300 on the 2005-2010 LX platform and the Town and Country (2003-2007) appear most frequently in PCM failure discussions. PT Cruiser ECM failures from the 2001-2006 model years are also common.
Every Chrysler Module Ships VIN-Programmed with Sentry Key Sync
Every Chrysler PCM, ECM, and TCM from Car Computer Exchange ships pre-programmed to the buyer's VIN with the latest factory software. No dealer visit. No separate programming fee. Plug it in and start the vehicle.
Chrysler vehicles from 1998 through 2017 use the SKIM (Sentry Key Immobilizer Module) anti-theft system. If the PCM and keys are not synced, the engine locks out. Car Computer Exchange pre-syncs the SKIM data during programming so the module arrives ready to install. After plugging in the new module, most Chrysler vehicles complete an idle relearn within a few key cycles.
Sensor inputs, fuel maps, CAN bus communication, and transmission shift logic all run through a 13-point quality check on a computer-aided vehicle simulator before any Chrysler module ships. The module is backed by a free lifetime warranty with core return within 21 days and a 60-day Iron-Clad Guarantee. Full warranty terms are available at the warranty page.
Chrysler owners with TIPM electrical issues (fuel pump relay failures, wiper or horn relay problems) should check the Chrysler TIPM repair service before replacing the PCM.
FAQs
How much does it cost to replace a Chrysler ECU?
Dealer replacement for a Chrysler ECU or PCM typically runs $800 to $1,500 or more, covering the part, labor, and a separate programming fee. A remanufactured, VIN-programmed replacement from Car Computer Exchange costs a fraction of the dealer price because it ships ready to install with no programming charge. Exact pricing depends on year, model, and engine size.
How do I know if my Chrysler PCM is failing?
A Chrysler PCM failing internally often shows up as P0601 or P0606 on the scan tool first, followed by a check engine light that will not clear, erratic shifting, rough idle, or stalling. If the scan tool returns "no communication with PCM" or multiple unrelated codes fire at the same time, the module itself is the likely source rather than individual sensors or coils.
Can I reset my Chrysler ECU myself?
Disconnecting the battery for 15 to 30 minutes resets the PCM's adaptive learning values (idle speed, fuel trim, shift points) but will not fix a hardware failure. If the same diagnostic codes return after the battery reset, the module itself needs replacement. A reset clears learned data only. It does not repair damaged memory or processors.
Do I need a dealer to program a Chrysler PCM?
Not with a VIN-programmed replacement. Car Computer Exchange pre-programs every Chrysler module to the buyer's exact VIN and pre-syncs the Sentry Key (SKIM) anti-theft data before shipping. Most buyers plug in the new module, cycle the ignition key, and start the vehicle with no dealer involvement and no extra programming fee.
What is the difference between a Chrysler PCM and TCM?
The PCM (powertrain control module) manages both engine and automatic transmission functions on most Chrysler vehicles. The TCM (transmission control module) is a separate module dedicated to transmission shifting on certain models, including the Town and Country, Sebring, and Chrysler 200. Both module types are available from Car Computer Exchange, matched to the buyer's VIN.
