2005-2006 Jeep Grand Cherokee Electronic Control Module (ECM) 56044742AC – Programmed to Your VIN

Picture this: You’re driving your 2005-2006 Jeep Grand Cherokee on a rugged trail, and suddenly the engine hesitates, throwing a check engine light. Rough idling kicks in, or worse, it stalls at a stoplight, leaving you stranded. These symptoms often stem from a failing ECM in the 3.7L 4×4 models, disrupting fuel delivery and ignition timing. As a mechanic with decades in the field, I’ve seen how a faulty module in the right-hand rear engine compartment causes power loss, poor fuel economy, and frustrating no-start conditions. This replacement arrives pre-programmed to your VIN and mileage, ensuring seamless integration. It matches part numbers like 56044742AC, 05094895AB, 05094898AA, 05094898AB, 05094898AC, 05094898AD, 05094898AE, 05094898ZB, 56044742AD, and 05094898AF. As a result, you avoid dealership visits and get back on the road quickly. Why does this matter? A precise match restores optimal performance, preventing minor glitches from escalating into major repairs.

Before installing this ECM, you might deal with erratic shifting or reduced power during acceleration, impacting your daily drives or off-road adventures. After swapping it in, expect smooth operation— the engine runs steadily, codes clear, and efficiency improves. Imagine regaining that reliable throttle response on highways or trails.

Conquer These Common Electronic Control Module Failures

In 2005-2006 Jeep Grand Cherokee models with the 3.7L engine and 4×4, ECM issues often arise around 100,000 miles due to heat exposure in the rear engine compartment. One frequent problem is intermittent stalling, caused by corrupted internal circuits affecting fuel injectors. As a result, drivers experience sudden power cuts during turns or idling. Another issue involves misfire codes like P0300, triggered by faulty sensor processing, leading to rough running and potential catalytic converter damage. Imagine noticing sluggish acceleration on inclines; that’s often from degraded voltage regulation in the module. Over time, water intrusion or vibration can exacerbate these, causing no-start scenarios. I’ve diagnosed plenty where the check engine light persists, pointing to communication errors with the transmission. Additionally, poor fuel mixture control results in black smoke or high emissions, failing inspections.

Replacing with this pre-programmed ECM clears codes like P0601 or P0128 swiftly, restoring normal operation and potentially saving $300 in shop fees. For instance, if you’re facing hesitation during cold starts, this unit recalibrates sensors for quick fixes. Test drive after install to confirm—smooth shifts and steady idle signal success. Pro tip: Check battery connections first, as weak power can mimic ECM faults.

Step-by-Step Installation Made Simple

1. Submit your VIN and mileage details when ordering to ensure proper programming.
2. Disconnect the battery and locate the ECM in the right-hand rear engine compartment for safety.
3. Remove the old unit by unplugging connectors and unbolting it carefully, using basic tools like a socket set.
4. Install the new ECM, securing it in place and reconnecting all wiring harnesses firmly.
5. Reconnect the battery, start the engine, and scan for codes to verify functionality.
6. If issues persist, double-check connections or consult a professional—now drive confidently with restored performance.
