Your Own 1996 Cherokee Computer, Rebuilt and Sent Back

This service assesses and repairs your 1996 Jeep Cherokee's own engine computer. If repair is successful, the same unit is returned tested. Nothing is dispatched to you first, and a replacement module is not included in this repair order.

There is no old core to send in afterwards either. The PCM you mailed is the core, and we already have it.

Parts catalogs give this box several names. A Cherokee runs one powertrain control module for the engine, and ECU, ECM, engine control module, PCM and plain engine computer all point at it.

Deciding the Computer Is Actually the Fault

A repair fixes the module, and that is all it fixes. It will not cure whatever killed the module, nor a fault that was never inside it. Settle the diagnosis before the unit leaves the vehicle, because shipping and bench time cost you either way.

A stored code is a starting point rather than a verdict. Codes naming the computer's memory or communication link warrant diagnosis. A sensor or circuit code calls for testing of that circuit; it does not by itself identify a failed sensor or PCM.

Work the supply side first. Confirm battery voltage at the module and clean grounds behind it, then pull the fuses and relays feeding it. Where a scan tool cannot reach the module at all, work through the no-communication checks that come first. Then look for the cause rather than the symptom. Water in the loom or a rubbed-through wire will finish off a rebuilt unit just as fast.

What Has to Match on a 1996 Cherokee

Three things decide whether this is your listing: the model year, the engine, and the module label.

The year is 1996, and that is not an arbitrary line. Published model history places the 1996 XJ Cherokee where Jeep's engine management moved to Chrysler's JTEC powertrain control module for the new OBD-II emissions rules, so a unit out of an earlier Cherokee is different hardware. If your Jeep is not a 1996, pick its year from our Jeep Cherokee engine computer catalog.

The engine is the 2.5L four-cylinder or the 4.0L inline-six, the two the XJ Cherokee carried in these years. One listing covers both, and nothing at checkout asks which one you have, so have your engine and your module label in front of you before we call.

No interchange list appears here on purpose. The published number sets for this application disagree with each other, so a number found elsewhere is not a fitment check. Read us your label instead.

The anti-theft question has a short answer on this year. Our Cherokee catalog puts the SKIM immobilizer on XJ models from 1998 onward, so a 1996 module is not that case. Still settle your install plan with us before anyone else touches the module.

Repair This Module, or Fit a Different One

Keeping your own PCM and fitting a different one are not the same job. This service repairs and returns the module you send in. A replacement is a different physical unit, and its configuration and installation requirements need to match your 1996 Cherokee.

On a 1996 Cherokee the choice is narrower than it looks. Car Computer Exchange rebuilds vehicle computers and does not sell salvage units, and our Cherokee catalog lists the 1996 engine computer as a send-in repair rather than one we ship out. A used module must match your vehicle. Include any required configuration and installation work when comparing its total cost with this repair service.

What Happens Once You Order

Ordering starts the paperwork, not the bench work. A prepaid label follows so your PCM reaches us at our cost, and we ask for your VIN once the order is through. Bench time counts from the day your unit arrives rather than the day you paid. Before it travels back it sits through the documented engine-computer routine Car Computer Exchange runs: a computer-aided vehicle simulator puts the module under load against the engine, the transmission, the emissions side and the anti-theft system.

What the Repair Warranty Covers, and What Ends It

Cover here comes out of the repair itself. Our policy issues its warranty on a part mailed in, worked on and sent back, so the 21-day core clock written for replacement orders never starts on your order.

The terms that decide what you actually hold:

• Lifetime length, no mileage cap, parts only. Labor, freight and handling sit outside it.
• Shipping a module in under warranty is at your cost.
• The cover belongs to you and not to the Jeep, so selling the Cherokee ends it.
• Two repair visits are covered. Past those two, further repair work on that unit falls outside it.
• Repair coverage does not include a free replacement for an unrepairable unit. Separately, the return policy sets a $125 testing and inspection fee for an unrepairable gas module costing less than $400. This service was listed at $279 on October 26, 2026. A paid repair order does not guarantee that the module can be repaired.
• Reprogramming done by any other source voids it outright.

Every limit and carve-out is written out on our warranty page.
