Part #4886867

The 1996 Dodge Ram 8.0L V10 uses one module — stamped 4886867 — to run both the engine and the automatic transmission. This PCM processes signals from the MAP sensor, throttle position sensor, crankshaft and camshaft position sensors, oxygen sensors, and vehicle speed sensor to maintain proper air-fuel ratio, ignition timing, and shift scheduling.

This controller is built on hardware base 05014153AA(96MDL) — the same board used across all 52 calibration stamps for the 1996 Ram V10. It bolts to the inner fender on the driver side, tucked behind the battery tray where it stays protected from direct engine heat and road spray.

Our remanufacturing process begins with a full teardown and ultrasonic cleaning of the original PCM board. Capacitors, driver chips, and any components showing signs of thermal stress are replaced. The rebuilt unit is run through an automated test cycle that simulates cranking, idle, cruise, and wide-open-throttle conditions before being flashed to your truck's VIN.

Installing Part 4886867

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 4886867

A failing PCM (part #4886867) on the 1996 Ram V10 commonly produces these warning signs:

• Random Multiple Fault Codes: The check engine light illuminates with a cluster of seemingly unrelated codes — oxygen sensor, MAP sensor, TPS, vehicle speed sensor — pointing to an internal PCM failure rather than individual sensor problems.
• 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.

Production Timing for 4886867

The stamp 4886867 identifies when in the 1996 model year this PCM calibration was released. The 488686x stamps are late production. They were issued toward the end of 1996 Ram 8.0L V10 assembly, after the 488674x and 488679x groups and before the final seven-digit run, 488693x. It is the last of 5 stamps in the 488686 group, following 4886866.

Other Ways 4886867 Is Written

4886867 also appears as P04886867, 04886867, and P4886867. 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 4886867

The Hollander cross-reference for part 4886867 is 590-04172 and 590-04173. Recyclers use those two numbers to catalog this V10 powertrain module. Confirm the label reads 4886867 before treating a yard unit as this calibration.

Fault Codes Tied to 4886867

On this calibration 4886867 (stamp 5 of 5 in the 488686 group), the codes below are the ones commonly stored when the module itself has failed. They are the pattern for the 488686 family, which is the late-production group.

• P0562 — System Voltage Low: P0562 reports system voltage below the threshold the controller expects. On late 1996 calibrations it often traces to the PCM once the alternator and battery cables have been ruled out.
• P0688 — Auto Shutdown Relay Control Circuit: P0688 means the controller is not driving the ASD relay control circuit correctly. A no-start with good fuel pressure and a good crank signal often ends at this code on a failed late-production module.

Emissions Certification for 4886867

This calibration meets Federal (50-state) emission standards for the 1996 model year. That is the certification on stamp 4886867, from the late-production group.

Manufacturing Date Suffixes after 4886867

Chrysler used letter suffixes (AA, AB, AC, etc.) after the base number to indicate manufacturing date. All suffixes for 4886867 are functionally identical and interchangeable. A label stamped 4886867AA, 4886867AB, or 4886867AC is this same calibration.
