Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Standard Motor Products EM317 Engine Control Module (ECM). The EM317 is a remanufactured Electronic Control Unit (ECU) designed to manage various engine functions, ensuring optimal performance and efficiency. Please read this manual thoroughly before proceeding with installation or operation.
Setup
Unpacking
- Carefully open the packaging and remove the EM317 Engine Control Module.
- Inspect the module for any signs of physical damage during shipping. If damage is found, do not proceed with installation and contact your supplier immediately.
- Verify that all components listed on the packing slip are present.
Installation
Installation of the EM317 ECM should only be performed by a qualified automotive technician. Incorrect installation can lead to vehicle damage or improper operation. Refer to your vehicle's specific service manual for detailed instructions on ECM removal and installation procedures.

Key Installation Steps:
- Disconnect the vehicle's battery to prevent electrical shorts.
- Locate the existing ECM in your vehicle. Its location varies by make and model (commonly under the dashboard, in the engine bay, or under a seat).
- Carefully disconnect all electrical connectors and mounting hardware from the old ECM.
- Install the new EM317 module, ensuring all connectors are securely fastened and mounting hardware is tightened to manufacturer specifications.
- Reconnect the vehicle's battery.
- Perform any necessary programming or relearn procedures as specified by the vehicle manufacturer. This often requires specialized diagnostic tools.
Operation
Initial Start-up
After successful installation and any required programming, the EM317 ECM will begin to operate automatically upon vehicle start-up. The ECM continuously monitors various sensors throughout the engine and vehicle systems to control fuel delivery, ignition timing, emissions, and other critical functions.
- Turn the ignition key to the 'ON' position (without starting the engine) for a few seconds to allow the ECM to power up and perform initial self-checks.
- Start the engine. Observe for any warning lights or unusual engine behavior.
- If the 'Check Engine' light illuminates, or if the vehicle exhibits poor performance, refer to the Troubleshooting section or consult a qualified technician.
The EM317 is designed to be a direct replacement for the original equipment ECM, providing reliable and consistent performance without requiring user interaction during normal operation.
Maintenance
General Care
The EM317 Engine Control Module is a sealed electronic component and requires minimal maintenance. However, proper care of your vehicle's electrical system can prolong its lifespan.
- Ensure all vehicle grounds are clean and secure. Poor grounding can affect ECM performance.
- Keep the ECM's surrounding area clean and free from excessive moisture, dirt, or debris.
- Avoid exposing the ECM to extreme temperatures or direct impacts.
- When performing other vehicle maintenance, ensure the battery is disconnected before working on electrical components to prevent accidental damage to the ECM.
Troubleshooting
This section outlines common issues that may arise and potential solutions. For complex problems, always consult a certified automotive technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Check Engine Light On | Faulty sensor, wiring issue, or incorrect ECM programming. | Scan for diagnostic trouble codes (DTCs) using an OBD-II scanner. Address the specific code. Verify ECM programming. |
| Engine Cranks but Won't Start | No fuel, no spark, or incorrect ECM signal. | Check fuel pressure and spark. Ensure all ECM connectors are secure. Verify proper ECM programming. |
| Rough Idling or Poor Performance | Sensor malfunction, vacuum leak, or ECM calibration issue. | Inspect sensors and vacuum lines. Check for pending DTCs. Consider professional diagnostic and recalibration. |
| No Communication with OBD-II Scanner | Blown fuse, wiring issue, or ECM internal fault. | Check relevant fuses (e.g., OBD-II port fuse). Inspect wiring to the ECM. If issues persist, the ECM may require professional testing. |
