DTC 93

CIRCUIT DESCRIPTION
The acceleration sensor detects vehicle vertical acceleration. The sensor has a piezoelectric ceramic disk supported at its center. When the vehicle accelerates, the ceramic disk flexes and the piezoelectric ceramic generates an electrical charge. The electrical circuit converts this electrical charge into voltage proportional to the acceleration, and outputs it to the ECU.
There is an acceleration sensor inside each front height control sensor, and one at the left rear. The deceleration of right rear is inferred from the data of the 3 sensors.




DETECTING CONDITIONS
Code 93 corresponds to the rear RH acceleration sensor circuit.
