DTC 16

CIRCUIT DESCRIPTION:
Codes 15, 16 and 17 are set when there is a short or open in the acceleration sensor circuit. Inspect the ECU, acceleration sensor and the harness/connectors between them.
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 right rear. The deceleration of the left rear is inferred from the data of the 3 sensors.
Once the ECU stores DTC 15, 16 or 17 in memory, damping force control is not carried out until a normal signal is input to the ECU from acceleration sensor. However, control is resumed if the ignition switch is turned off, then on again.

^ Code 15 corresponds to the front RH acceleration sensor circuit.
^ Code 16 corresponds to the front LH acceleration sensor circuit.
^ Code 17 corresponds to the rear RH acceleration sensor circuit.

INSPECTION PROCEDURE
^ When DTC 15 is displayed, check front RH acceleration sensor circuit.
^ When DTC 16 is displayed, check front LH acceleration sensor circuit.
^ When DTC 17 is displayed, check rear RH acceleration sensor circuit.
