Lexus NX: Vehicle Control History
VEHICLE CONTROL HISTORY
CHECK THE VEHICLE CONTROL HISTORY (LIGHTING SYSTEM)
HINT:
- The vehicle control history data (lighting system) stores the history of the reject function and system protection operations.
- The number of occurrences, date and distance are stored in batches for each item.
