Product Details

Cardone’s Engine Control Module line focuses on remanufactured electronic and powertrain control units that are built to meet or exceed original equipment performance. For this Nissan D21 ECM, the remanufacturing process includes inspection of common failure points, correction of original design weaknesses where applicable, and testing at Cardone’s Philadelphia manufacturing plant. The result is a direct-fit control module for the 1994 Nissan D21 that supports stable engine management and consistent electrical communication.

This part cross-references Nissan OE numbers 23710-3B105 and 23710-3B107 for the same application. The part number 72-3581 is also useful when verifying the correct replacement against the original module.

Common Problems This ECM Can Address

• No-start or intermittent start conditions related to control module failure
• Rough running caused by incorrect fuel or ignition control signals
• Check engine light concerns tied to ECM malfunction
• Driveability issues from failed internal solder joints or electronic components
• Communication problems caused by a damaged original module

Installation Notes

Before replacing the original ECM, verify the root cause of the failure. Common causes include poor grounds, power supply issues, damaged wiring harnesses, and shorted solenoids or relays. Confirm the original Nissan engineering number matches the correct Cardone application before installation. This unit is listed for the 1994 Nissan D21 without California Emission System and is pre-programmed at the factory.

Quality Assurance

Each Cardone remanufactured ECM is tested with automated computer equipment or bench-tested, depending on application, to confirm functionality. Re-soldering or replacement of critical components helps improve electrical connection quality and long-term reliability. The remanufacturing process also reduces the energy and raw material required to produce a new part by about 80%.
