Part #4886932

Part number 4886932 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.

Every calibration in this group shares Chrysler hardware platform 05014153AA(96MDL). The module mounts on the driver-side inner fender, behind the battery tray, secured with factory bolts to a stamped steel bracket. Two multi-pin weatherpack connectors carry all sensor inputs and actuator outputs.

Each replacement unit is completely remanufactured: the original board is ultrasonically cleaned, failed components are replaced with updated parts where applicable, and every circuit is tested on a dedicated bench simulator that replicates real-world V10 operating conditions. The module is then programmed to your specific 17-digit VIN before it ships.

Installing Part 4886932

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 4886932

When part number 4886932 fails on a 1996 Ram 8.0L V10, the truck typically shows one or more of these symptoms:

• 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.
• OBD-II Scanner No-Communication: A handheld scan tool or shop diagnostic computer reports no communication when connected to the 16-pin data link connector under the dash, indicating the PCM is not responding on the J1850 data bus.
• Automatic Transmission Limp Mode: The four-speed automatic defaults to second or third gear and will not shift through all forward gears, often accompanied by the check engine light and transmission-related fault codes.

Production Timing for 4886932

Part number 4886932 dates to a specific point in the 1996 Ram 8.0L V10 production calendar. The 488693x stamps are the final seven-digit production run for this PCM. Chrysler later supplied Mopar remanufactured service parts from this same calibration, marked with an R prefix: R4886930, R4886932, and R4886933. It is stamp 3 of 5 in the 488693 group, between 4886931 and 4886933.

Other Ways 4886932 Is Written

4886932 also appears as P04886932, 04886932, and P4886932. 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 4886932

Hollander lists 4886932 under interchange numbers 590-04172 and 590-04173. Both numbers identify the 1996 Dodge Ram 8.0L V10 PCM. The Hollander entry covers the hardware. The calibration stamped on the case still has to be 4886932.

Fault Codes Tied to 4886932

On this calibration 4886932 (stamp 3 of 5 in the 488693 group), the codes below are the ones commonly stored when the module itself has failed. They are the pattern for the 488693 family, which is the final seven-digit production run.

• P0562 — System Voltage Low: The PCM stores a low system-voltage code. After charging voltage at the battery checks out, the usual cause on these later stamps is the module's internal power supply.
• P0688 — Auto Shutdown Relay Control Circuit: The auto-shutdown relay control circuit is flagged. The engine can crank with no injector pulse or spark if the PCM can no longer operate the ASD relay.

Emissions Certification for 4886932

This calibration meets Federal (50-state) emission standards for the 1996 model year. That is the certification on stamp 4886932, from the final seven-digit production run.

Letter Suffixes on 4886932

Chrysler used letter suffixes (AA, AB, AC, etc.) after the base number to indicate manufacturing date. All suffixes for 4886932 are functionally identical and interchangeable. A label stamped 4886932AA, 4886932AB, or 4886932AC is this same calibration.
