As a past malfunction, the customer will not notice it (no warning light illuminated), but the DTC may be
found during a vehicle service. P2507 in this situation is only applicable on 2016 and later models.
This is caused by the engine being started 3 or more times after a short duration of engine off (less than 15
seconds) with the room fused removed.
NOTE: The odometer will display “F0-002” during transport mode (room fuse 15A removed). Transport
mode is canceled when room fuse 15A is installed or the vehicle odometer is more than 12.4mi (20km).

Vehicles in dealer inventory with this concern should be repaired using the following repair procedure.
