P149500 — Immobiliser authentication failed
Quick answer
P149500 indicates that the motor controller did not receive valid immobiliser authentication, so the car will not start.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- High-voltage system: do not open or disconnect high-voltage components. Refer the car to a technician qualified for high-voltage work.
Can I still drive?
