Inspection Procedure 2: Neither right nor left automatic leveling operates.: Operation
When a vehicle is at a standstill or being driven at a constant speed for 12 seconds or more (except on rough road), the headlight automatic leveling ECU inputs a headlight relay (LOW) signal, vehicle speed signal, and height signal for judgment and operates the headlight leveling.
NOTE:
The automatic leveling during driving at a constant speed operates only once after starting driving. The automatic leveling does not work if the vehicle pitch angle during driving at a constant speed and the vehicle pitch angle when the vehicle is stopped are the same.
