Cause
Error code 25E indicates that the ECU is not sending out a regular heartbeat signal to the meter. This could be due to:
- Faulty ECU: The ECU itself might be malfunctioning, preventing it from sending the heartbeat signal.
- Loose connection: The connection between the ECU and the meter might be loose, interrupting the signal.
Fix
- Check if the connection of the ECU is loose.
- Change the ECU.
