Part #56040867

56040867 identifies a factory-calibrated Powertrain Control Module for the 1996 Dodge Ram Truck equipped with the 8.0L (488 cubic inch) Magnum V10. Chrysler's largest gasoline engine of the era, the V10 relies on this single PCM to coordinate fuel metering across ten cylinders, manage exhaust gas recirculation, and control the four-speed automatic transmission shift strategy.

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.

How to Install Part #56040867

You will need a 10mm socket and about 20 minutes. Disconnect the battery ground strap first. The original module is on the inner fender, driver side, behind the battery tray. Detach the two weatherpack connectors by pressing the release tabs, remove the hold-down bolts, and lift the module out. Set the replacement in place, torque the bolts, snap the connectors back in, and reconnect the battery. The module ships fully programmed — your existing keys, fobs, and transmission adaptation all carry over.

Symptoms That Point to Part 56040867

If the original 56040867 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.

Where 56040867 Falls in the 1996 Model Year

Calibration 56040867 was not used for the entire model year. Chrysler assigned it to one stretch of 1996 production. The 560408xx stamps are the late eight-digit series. By the time these calibrations were released, Chrysler was numbering 1996 Ram V10 PCMs only in the 5604xxxx format. It is stamp 5 of 6 in the 560408 group, between 56040866 and 56040868.

Catalog Spellings of 56040867

Search 56040867 together with P056040867, 056040867, and P56040867. The extra characters are how parts catalogs expand an eight-digit Chrysler calibration. The number underneath is still 56040867.

Hollander Lookup for 56040867

Salvage-yard lookups for 56040867 use Hollander 590-04172 / 590-04173. The 560408 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.

Diagnostic Codes for Calibration 56040867

Diagnostic trouble codes for a bad 56040867 module follow the 560408 family pattern. Check these before replacing sensors on a truck that is still running this calibration:

• P1391 — Intermittent Loss of CKP or CMP: Chrysler's code for an intermittent loss of the crankshaft or camshaft position signal. On these eight-digit calibrations it is commonly stored when the PCM stops processing those inputs consistently.
• P1698 — No CCD Message from TCM: The PCM reports that no CCD-bus message is arriving from the transmission control side. On these calibrations the code is commonly stored when the module's own bus communication fails.

Emissions Certification for 56040867

This calibration meets Federal (50-state) emission standards for the 1996 model year. Trucks that left the factory on calibration 56040867 were covered by that federal certification.

AA, AB, and AC Suffixes for 56040867

Chrysler used letter suffixes (AA, AB, AC, etc.) after the base number to indicate manufacturing date. All suffixes for 56040867 are functionally identical and interchangeable. Ignore the trailing letters when matching a core. 56040867AC is still 56040867.
