Part #4886747

Part number 4886747 is an OEM Powertrain Control Module (PCM) engineered for the 1996 Dodge Ram 2500 and 3500 Truck with the 8.0L Magnum V10. This ten-cylinder engine was exclusive to the heavy-duty Ram lineup and requires a dedicated PCM to manage its sequential multiport fuel injection, distributorless ignition, and electronically controlled automatic transmission.

Hardware code 05014153AA(96MDL) is printed on the module's circuit board and is common to every 1996 Ram 8.0L V10 PCM regardless of calibration stamp. The unit attaches to the driver-side inner fender behind the battery tray via two or three mounting bolts, with the wiring harness connecting through two large multi-pin Mopar weatherpack plugs.

Before shipping, every module goes through a multi-stage remanufacturing process: board-level inspection under magnification, replacement of known failure-prone components (power transistors, capacitors, voltage regulators), full functional bench testing, and custom VIN programming with your truck's exact 17-digit identification number.

Installing Part 4886747

Installation takes about 20 minutes with basic hand tools. Disconnect the negative battery cable, locate the existing module on the driver-side inner fender behind the battery tray, unplug the two wiring harness connectors, and remove the mounting bolts. Reverse the process with the replacement unit. Because the PCM arrives pre-programmed to your VIN, there is no dealer visit, no locksmith, and no scan tool reflash required — turn the key and drive.

Symptoms That Point to Part 4886747

If the original 4886747 module is going bad in your 1996 Ram 8.0L V10, expect some combination of the following:

• Dead Pedal / Sudden Throttle Loss: The throttle response drops to zero while driving, the engine falls to idle, and the truck limps at low speed until the ignition is cycled off and back on.
• No-Bus Message on Instrument Cluster: The odometer area of the gauge cluster displays 'No Bus' instead of mileage, indicating the PCM has dropped off the vehicle's CCD data bus and is no longer communicating with the body and instrument modules.
• Intermittent Stalling at Operating Temperature: The engine runs normally when cold but begins cutting out after reaching full operating temperature, sometimes restarting after a cool-down period of 20 to 30 minutes.
• Crank / No-Start Condition: The starter motor cranks the engine at normal speed but the engine will not fire due to loss of fuel injector pulse or ignition coil trigger signal from the PCM.

Production Timing for 4886747

Calibration 4886747 was not used for the entire model year. Chrysler assigned it to one stretch of 1996 production. The 488674x stamps are the mid-production run. Chrysler issued this series once 1996 Ram 8.0L V10 assembly was established, after 4849358, 4849359, the 4850xxx revisions, and the standalone 4853980 calibration. It is the first of 6 stamps in the 488674 group. The other numbers are 4886748, 4886749, 4886750, 4886751, 4886756.

Other Ways 4886747 Is Written

4886747 also appears as P04886747, 04886747, and P4886747. These are the same number. Different sources print them differently: a P catalog prefix, a leading zero that fills the eight-digit parts field, or both.

Hollander Cross-Reference for 4886747

Salvage-yard lookups for 4886747 use Hollander 590-04172 / 590-04173. The 488674 family is filed under that same pair, along with every other 1996 Ram V10 PCM calibration on this hardware. Match the stamp, not only the Hollander number.

Fault Codes Tied to 4886747

On this calibration 4886747 (stamp 1 of 6 in the 488674 group), the codes below are the ones commonly stored when the module itself has failed. They are the pattern for the 488674 family, which is the mid-production run.

• P0340 — Camshaft Position Sensor Circuit: The PCM flags the camshaft position sensor circuit. On a failing module from this family the code can set while the sensor, connector, and tone wheel still test in spec, because the controller has stopped reading the CMP signal.
• P0720 — Output Speed Sensor Circuit: The transmission output-speed input is reported bad. Limp-mode shifting often shows up with it when the PCM, rather than the output speed sensor, has failed.

Emissions Certification for 4886747

This calibration meets Federal (50-state) emission standards for the 1996 model year. That is the certification on stamp 4886747, from the mid-production run.

AA, AB, and AC Suffixes for 4886747

Chrysler used letter suffixes (AA, AB, AC, etc.) after the base number to indicate manufacturing date. All suffixes for 4886747 are functionally identical and interchangeable. A label stamped 4886747AA, 4886747AB, or 4886747AC is this same calibration.
