Chrysler Concorde PCM, ECM & ECU

Chrysler Concorde PCM, ECM and ECU Replacement Modules

Car Computer Exchange remanufactures Chrysler Concorde PCMs, ECMs, and ECUs for 1998 to 2004 models, plus transmission control modules for 1998 to 2002. Every engine computer is matched to your vehicle and tested before it ships. You get the same module a dealer would install, without the dealer price.

What a Chrysler Concorde PCM controls, and how it differs from the TCM

On the Chrysler Concorde, the terms PCM, ECM, and ECU all refer to the same engine computer. It manages fuel injection, ignition timing, and emissions so the engine starts and runs correctly. The transmission control module (TCM) is a separate unit that controls shifting. Car Computer Exchange stocks both: engine computers for 1998 to 2004 Concordes and TCMs for 1998 to 2002.

Signs your Chrysler Concorde PCM is failing

A failing Chrysler Concorde PCM usually shows up as a car that will not start or will not run right, often after a scan tool points at the engine computer. Common symptoms:

• No-start or a long crank with no ignition, even when the battery and starter are good
• A check engine light that returns after you replace sensors or coils
• Random stalling, rough idle, or misfires
• Poor fuel economy or a clear drop in power
• Internal module codes such as P0601 (memory checksum error) or the P0600 to P0607 range, which point at the computer itself rather than a sensor

Because these symptoms overlap with sensor and wiring faults, confirm the diagnosis with a scan tool before you replace the module. Shifting problems point to the transmission control module (TCM), a separate unit, not the engine computer.

VIN programming and what is included

Every Chrysler Concorde engine computer from Car Computer Exchange is programmed to your VIN before it ships, so it arrives matched to your vehicle. Chrysler vehicles from this era use the Sentry Key Immobilizer (SKIM) anti-theft system, so some installs need a short key relearn once the module is in. Whether your specific module needs that step is listed on its product page. Give us your VIN at checkout and we handle the programming, then tell you exactly what, if anything, is left to do.

How each module is tested and backed

Before any Chrysler Concorde engine computer ships, Car Computer Exchange runs it through a 13-point quality check on a computer-aided vehicle simulator that emulates the engine, transmission, emissions, and anti-theft systems. Each module carries a free lifetime warranty with core return and a 60-day money-back guarantee: if it does not solve your vehicle's issue, return it for a refund or exchange, with processing fees applied. Behind that process, Car Computer Exchange has served more than 150,000 customers since 2011.

Chrysler Concorde PCM, ECM and TCM fitment by year

This collection fits the second-generation, LH-platform Chrysler Concorde. Engine computers (PCM, ECM, ECU) cover 1998 to 2004, and transmission control modules cover 1998 to 2002. Match the module to your exact model year, such as the 1998 Concorde PCM or the 2004 Concorde PCM. The Concorde shares the LH platform with the Chrysler 300M, so we carry modules for that model too.

FAQs

Are the Chrysler Concorde PCM and ECM the same thing?

Yes. On the Chrysler Concorde, PCM, ECM, and ECU all name the same engine computer, the module that controls fuel injection, ignition timing, and emissions. Sellers and repair guides use the terms interchangeably. The transmission control module (TCM) is a different unit that manages shifting, and we sell it separately for 1998 to 2002 Concordes.

How do I know if my Concorde PCM is bad?

A bad Concorde PCM usually causes a no-start, random stalling, rough idle, or a check engine light that returns after you replace sensors. A scan tool may store internal codes such as P0601. Because these symptoms overlap with sensor and wiring faults, confirm the diagnosis with a scan tool before you replace the module.

Do I need a dealer to program a Chrysler Concorde PCM?

No. Car Computer Exchange programs each Concorde engine computer to your VIN before it ships, so it arrives matched to your vehicle. Chrysler's Sentry Key Immobilizer system means some installs still need a short key relearn, which the product page spells out. We tell you what is included and what, if anything, is left to do.

Will my Concorde run without a working PCM?

No. The PCM is the engine computer, so the Concorde will not start or run properly without a working one. If the module has failed, the car may crank without firing or stall soon after starting. A VIN-programmed replacement restores normal operation.

What years and modules does this collection fit?

This collection covers the second-generation Chrysler Concorde. Engine computers (PCM, ECM, ECU) fit 1998 to 2004 models, and transmission control modules fit 1998 to 2002. Each listing is tied to a specific model year, so match the module to your vehicle.

What comes with the module, and what is the warranty?

Each Chrysler Concorde engine computer ships programmed to your VIN and tested. It is covered by a free lifetime warranty with core return and a 60-day money-back guarantee: if the module does not fix your vehicle's issue, return it for a refund or exchange, with processing fees applied. Provide your VIN at checkout so we can program the unit before it ships.
