DTC B2416 Height Control Sensor Malfunction

DTC B241A Rear Height Control Sensor


DESCRIPTION

The DTC is stored when the headlight swivel ECU*1 or headlight leveling ECU*2 detects malfunctions in the rear height control sensor LH power source or rear height control sensor LH (w/o Active Height Control Suspension).
  1. *1: w/ Dynamic Headlight Auto Leveling
  2. *2: w/ Static Headlight Auto Leveling
The headlight swivel ECU receives signals indicating the height of the vehicle from the suspension control ECU (w/ Active Height Control Suspension).
