Detailed Description

Cardone Part Number 79-7597 is an engine control module designed for Chrysler-era applications that require a remanufactured ECM with OE-style fit and operation. It is listed for 1991 Dodge Shadow and 1991 Plymouth Sundance models with Federal Emission System, and it cross-references OE numbers 4557597, 4686588, and 5285477. This part number is also identified as a direct replacement for the same application family, making it a practical choice when replacing a failed factory module.

Cardone remanufactures these control modules by reverse engineering failure points, then correcting known weaknesses through re-soldering or replacement of critical internal components. Each unit is tested with computer equipment or bench-tested depending on application, helping confirm proper operation before installation. Cardone 79-7597 is a remanufactured ECM for Dodge Shadow and Plymouth Sundance owners who need a factory-style electronic control solution without flash programming.

What It Can Help Resolve

• Engine no-start conditions caused by a failed ECM
• Intermittent drivability problems tied to control module faults
• Check engine concerns related to electronic module failure
• Communication or control issues from damaged internal circuitry
• Replacement needs after diagnosing the original module as the fault source

Installation Notes and Tips

• Fits 1991 Dodge Shadow, N/A, with Federal Emission System and OE # 4557597, 4686588, 5285477.
• Fits 1991 Plymouth Sundance, N/A, with Federal Emission System and OE # 4557597, 4686588, 5285477.
• Verify the original ECM/PCM failure before replacement by checking grounds, power feeds, wiring harness condition, and related relays or solenoids.
• Confirm connector style, terminal count, and OE number match the vehicle before installation.
• Chrysler PCM units identified with a V suffix require VIN programming; verify application details before ordering.

Quality Assurance

Cardone remanufactured electronic and powertrain control modules are built to meet or exceed OE performance targets through controlled remanufacturing and testing. The process includes component-level correction, computer validation, and application-specific testing to support reliable operation in the vehicle.
