1996 Chrysler Town & Country 3.3L PCM Replacement Guide
The powertrain control module (PCM) in your 1996 Chrysler Town & Country 3.3L is the main computer that manages engine and transmission operation. When it fails, the vehicle may not start, run poorly, or set internal fault codes like P0601.
Quick Summary
- The PCM controls fuel injection, ignition timing, and transmission shift points in your 1996 Town & Country.
- Failure often results in no-start, stalling, or a check-engine light with codes P0600, P0601, or P1698.
- Replacement requires 0.6 hours labor for removal and installation, plus a 0.5-hour relearn procedure.
- Factory service bulletin 18-037-05 covers flash programming recovery using a DRBIII scan tool.
- A VIN-programmed replacement PCM from Flagship One arrives ready to install, eliminating the factory relearn step.
If your 1996 Chrysler Town & Country 3.3L is experiencing intermittent stalling, a no-start condition, or a check-engine light that won’t go away, the powertrain control module (PCM) may be the culprit. The PCM is the main computer that coordinates engine and transmission functions. This article explains what the PCM does in your minivan, where it is located, how replacement is performed, and what symptoms to watch for. You will also learn about the factory relearn procedure and how a pre-programmed replacement unit can simplify the repair.
What the PCM Does in a 1996 Chrysler Town & Country
The powertrain control module (PCM) in your 1996 Chrysler Town & Country 3.3L is a single computer that integrates engine control and transmission control functions. It receives input from sensors such as the crankshaft position sensor, throttle position sensor, and oxygen sensors, then adjusts fuel delivery, spark timing, and shift patterns accordingly. When the PCM fails, it can cause a range of drivability issues because the engine and transmission no longer receive correct commands. For this vehicle, replacement PCMs for the Town & Country are available that match the original specifications. The module is critical for meeting emissions standards and ensuring smooth operation, so a faulty unit should be addressed promptly.
Where the PCM Is Located and What Replacement Involves
The PCM in a 1996 Chrysler Town & Country 3.3L is typically mounted in the engine compartment, often on the driver-side inner fender or near the battery. Replacement involves disconnecting the battery, removing the electrical connectors, unbolting the module, and installing the new unit. According to factory labor times, the removal and replacement (R&R) of the PCM is allotted 0.6 hours. After installation, a relearn procedure is required, which is listed at 0.5 hours. Access may require removing an air intake duct or other components, but the job is straightforward for a competent DIYer or professional mechanic.
How to Reach the PCM on the 1996 Chrysler Town & Country
- Disconnect both cables from battery, negative cable first.
- Remove 2 screws holding Power Distribution Center (PDC) to bracket distributioncenter.
- Remove heat shield from battery heatshieldbattery.
- Remove nut and clamp holding battery to battery tray clampnut.
- Remove battery from vehicle.
- Rotate PDC toward center of vehicle to remove from rear bracket.
- Pull PDC rearward to remove from front bracket.
- Remove 3 screws holding PCM to fender.
- Remove PCM from vehicle.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Powertrain Control Module R&R | All configurations | 0.6 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 0.6 hr |
Programming Requirements After Replacement
After installing a new PCM in your 1996 Chrysler Town & Country 3.3L, the factory procedure requires a relearn process using a DRBIII scan tool, as outlined in service bulletin 18-037-05. This step ensures the module syncs with the vehicle’s security system and learns idle parameters. The relearn is allotted 0.5 hours of labor. However, when you purchase a VIN-programmed replacement PCM from Flagship One, the module arrives with your vehicle’s VIN and calibration already loaded. This means the factory relearn step is already completed, so you can install the unit and drive without needing a dealer visit.
Symptoms of a Failing PCM
A failing PCM in your 1996 Chrysler Town & Country 3.3L may cause the engine to crank but not start, or it may start and stall shortly after. You might notice erratic shifting, hesitation during acceleration, or a check-engine light that stays on. The scan tool may fail to communicate with the module. Internal trouble codes such as internal controller failure P0601 indicate a problem within the PCM itself. Other symptoms include misfire codes that do not correspond to a specific cylinder, or the transmission refusing to shift out of a single gear. If you experience these issues, the PCM should be tested before replacing other components.
Module Trouble Codes on the 1996 Chrysler Town & Country
The following trouble codes are documented for the 1996 Chrysler Town & Country 3.3L and indicate internal PCM faults. These codes require diagnosis of the module itself rather than external sensors or wiring.
