C1726

DTC C1726 Open or Short Circuit In Left Front Suspension Control Actuator Circuit

CIRCUIT DESCRIPTION

DTC Detection Condition:

The absorber control actuator is step motor that consists of permanent magnet and 2 pairs of stator (electromagnet). It meticulously rotates the permanent magnet, which is directly connected to the absorber control rod, in accordance with the signals from the suspension control ECU to control the damping force.

HINT:
- Code C1725/21 corresponds to the right front suspension control actuator circuit.
- Code C1726/22 corresponds to the left front suspension control actuator circuit.
- Code C1727/23 corresponds to the right rear suspension control actuator circuit.
- Code C1728/24 corresponds to the left rear suspension control actuator circuit.

Once the ECU stores DTC C1725/21 C1726 /22, C1727/ 23 or C1728/24 in memory, the damping force control is not carried out until a normal signal is input to the ECU from the suspension control actuator.

However, the control is resumed if the ignition switch is turned OFF, then ON again.

INSPECTION PROCEDURE

HINT:
- When DTC "C1725/21" is displayed, check the right front suspension control actuator circuit.
- When DTC "C1726/22" is displayed, check the left front suspension control actuator circuit.
- When DTC "C1727/23" is displayed, check the right rear suspension control actuator circuit.
- When DTC "C1728/24" is displayed, check the left rear suspension control actuator circuit.
- When DTC C1725/21, C1726/22, C1727/23 and C1728/24 are displayed, perform inspection of step 2.
