Charger displays E17 and charging stops; may be associated with DC leakage detection.

Shock hazard: DC leakage faults are serious. If E17 appears repeatedly, discontinue use until the cause is identified.

• Step 1 – Dry environment: Ensure the charger and connector are completely dry. Moisture can cause false DC leakage readings.
• Step 2 – Visual inspection: With power off, inspect the DC residual current sensor (often a specialized core around the conductors) for cracks or water ingress.
• Step 3 – Wiring check: Confirm that all phase and neutral conductors pass through the sensor as designed and that none are bypassing it.
• Step 4 – Test with another EV: If possible, test with a different vehicle to rule out DC leakage from the car's onboard charger.
• Step 5 – Replace sensor: If the issue follows the charger, replace the BougeRV DC residual current sensor module. If E17 persists, the main board's detection circuit may be defective.
