Diagnosis Description

FUNCTION

Diagnostic test mode	Function
ECU Identification	VCM part number is displayed.
Self Diagnostic Result	DTCs and freeze frame data can be read and erased quickly. ^*1
Data Monitor	Input/Output data in the VCM can be read.
Active Test	Diagnostic Test Mode in which CONSULT drives some actuators apart from VCM and also shifts some parameters in a specified range.
Work Support	This mode enables a technician to adjust some devices faster and more accurately by following the indications on the CONSULT.

*1: The following diagnosis information is cleared when the VCM memory is erased.

SELF-DIAGNOSIS RESULT MODE

SELF-DIAGNOSIS ITEM

For DTC item, Refer to DTC Index.

How to delete the self-diagnosis result

If the power switch remains on after detecting DTC, press and hold the power switch for at least 2 seconds to turn off the high voltage system and check that the charge indicator is off. After turning off the high voltage system, open the driver's door, get out the car, close the driver's door, wait for 5 minutes or more, turn on the power switch again, and then erase the DTC.
Check all self-diagnosis screens and make sure there are no DTCs on other ECUs.

CAUTION:

When the VCM is self-shut off while the power switch is turned off, never operate the door lock and the door open and close. If the Nissan Ariya vehicle is operated, wait at least 5 minutes again from that point.

Counter System

Diagnosis Description

In this system, “Power switch is turned OFF⇒ON” is defined as 1 trip. VCM detects malfunctions while saving the DTC and freeze frame data and continues saving this data for a maximum of 40 trips. In addition, if a DTC that is the same as the saved DTC is detected again, the counter is reset and the count up starts from “0” again.

Dtc and Freeze Frame Data

Diagnosis Description

VCM can store multiple DTCs and Freeze Frame data.

After the detection of a malfunction and storing of DTC and Freeze Frame data by VCM, if a different malfunction is detected, multiple DTCs can be identified. In contrast, multiple Freeze Frame Data are stored according to the preset priority. If detected malfunction too many, some FREEZE FRAME DATA may not stored.

The DTC and freeze frame data are deleted when the self-diagnostic is deleted.

On Board Diagnosis Function

Diagnosis Description

VCM is compatible with on-board diagnosis systems, and when malfunction occurs in the system, it automatically is detected. A malfunction information is stored in the memory of VCM as DTC and can be obtained with CONSULT.
