JAECOO 7 PHEV: Vehicle cannot start after severe traction battery depletion
Symptoms
- The vehicle displays a low traction battery charge warning and cannot start after severe depletion. [1]
Possible causes
- The manual states that prolonged use of electrical equipment after powering on the vehicle can deplete the traction battery, and severe depletion may prevent starting; do not confuse this with a 12V fault. [1]
Checks
- Verify the low-charge warning; confirm that P is selected and the vehicle is parked, and observe other warning lights. Contact a service centre if abnormalities occur. [1]
What to do
- The manual permits connecting a charging connector to charge when severe traction battery depletion prevents starting; contact a service centre if the vehicle still cannot start. [1]
