B2514 HEIGHT SENSOR UNUSUAL [RR]
B2514 HEIGHT SENSOR UNUSUAL [RR]
Description
INFOID:0000000003135298
The height sensor is installed to the rear suspension arm. The height sensor detects the suspension arm dis-
placement as the vehicle height change. The height sensor transmits the height sensor signal to AFS control
unit.
NOTE:
The sensor angle of the unloaded vehicle position is the reference value.
