Remanufactured Engine Control Module

CARDONE 77-8708 is a remanufactured engine control module built for direct replacement in select Chrysler-era applications. It is engineered to restore proper engine management, with testing and component-level refurbishment focused on reliability and OE-style fit.

This module is a practical choice for diagnosing and replacing a failed ECM on a 1990-1991 Oldsmobile Cutlass Supreme or 1990-1991 Pontiac Grand Prix. The CARDONE Engine Control Module line emphasizes remanufactured OE fitment and validated performance for vehicles that need accurate electronic control.

Key Features

  • Remanufactured Original Equipment-style ECM for direct fitment
  • Critical components are re-soldered or replaced at CARDONE’s Philadelphia manufacturing plant
  • 100% computer tested for functionality and reliability
  • On-car validation used to confirm durability and performance
  • Earth-conscious remanufacturing process reduces raw material and energy use versus building a new part

Detailed Description

CARDONE 77-8708 is designed to meet or exceed original equipment performance for vehicles using this engine control module application. Reverse engineering of failed units helps identify common design weaknesses, and the remanufacturing process addresses those failure points before the module is returned to service. For drivers and technicians working on a 1990-1991 Oldsmobile Cutlass Supreme or 1990-1991 Pontiac Grand Prix, this ECM supports accurate fuel and ignition control when the original module has failed.

This part cross-references Oldsmobile and Pontiac OE numbers 1228708 for the same application.

What It Can Help Resolve

  • No-start condition caused by a failed engine control module
  • Intermittent drivability problems tied to ECM electronics
  • Check engine concerns related to control module failure
  • Erratic engine performance from damaged internal circuitry
  • Communication or control issues after the original module has deteriorated

Installation Notes and Tips

  • Fits 1990-1991 Oldsmobile Cutlass Supreme, N/A.
  • Fits 1990-1991 Pontiac Grand Prix, N/A.
  • Transfer PROM(s)/CALPACK from the original module before installation.
  • Perform any required relearns after installation.
  • Before replacing the ECM, inspect grounds, power feeds, wiring harness condition, and related solenoids or relays.
  • Verify the Ford Engineering ID note does not apply here; use the correct OE cross-reference for this application.

Quality Assurance

Each CARDONE remanufactured ECM is computer tested, and critical electrical connections are restored during the remanufacturing process. The unit is validated for durability and performance before release, supporting dependable operation in the intended vehicle applications.
