DTC C03 Front Vertical Accel Sensor Circuit Malfunction

DIAGNOSTIC TROUBLE CODE (DTC) C03

FRONT VERTICAL ACCELERATION SENSOR CIRCUIT MALFUNCTION

Circuit Description
The acceleration sensor provides a voltage signal that changes in relation to the acceleration of vehicle. The signal voltage will vary from about 0.5 to 4.5 volt.e0m The ICSM use this voltage to control damping force.

Diagnosis
This procedure checks for a malfunctioning vertical acceleration sensor, a short to ground or to voltage in the wiring, or a contact problem in a connector.

Cause(s)
- The vertical acceleration sensor is defective or disconnected
- There is a problem in the wiring
- There is a problem with a connector
- Wrong installed vertical acceleration sensor

Fail Action
ICS action is disabled and ICS warning lamp is ON.

Test Description
2. This step checks the voltage reference from the ICSM and also the ground wire to the ICSM.
4. This step check the vertical acceleration sensor for internal defect.

Diagnostic Aids
Be sure that the acceleration sensor wiring is properly routed and retained.
It is very important to perform a thorough inspection of the wiring and the connectors carefully and completely may result in misdiagnosis, causing part replacement with the reappearance of the malfunction.
You can use the scan tool to monitor vertical acceleration sensor during a road test. Watch the vertical acceleration sensor being displayed on the scan tool to see if any of the readings is unusual.
