17069/P0685 - ECM Power Relay Control Circuit (J271): Open Circuit
Possible Symptoms
- Malfunction Indicator Light (MIL) ON
- Engine doesn't start
Possible Causes
- Voltage supply issue for ECM
- Faulty ECM Relay (J271)
Possible Solutions
- Test voltage supply to ECM
- Check wiring and fuses
- Replace Faulty ECM Relay (J271)
Special Notes
- When found in a 2005 through 2007 2.5L NAR (North American Region) (1K) Jetta check the T121/62 (Red/Black) traced power wire to the ECM. If power is missing or a voltage drop is present that wire may be damaged anywhere between 6" and 18" from the connector itself. This will result in no communication in addition to a no-start.
- Based on 2.5L Jetta feedback over the years a majority look like this example however some are damaged further away per this example: with the close-up and distant views.
