Diagnosis Description

APPLICATION ITEM

CONSULT can display each diagnostic item using the diagnostic test modes as follows.

Diagnosis mode Note
 
Self Diagnostic Result Display DTC which Electrically-driven Intelligent Brake Unit memorizes
Data monitor Displays Electrically-driven Intelligent Brake Unit input/output data in real time
Active test Enables an operational check of a load by transmitting a driving signal from the Electrically-driven Intelligent Brake Unit to the load
ECU Identification Displays Electrically-driven Intelligent Brake Unit part number
Replace ECU Write the Nissan Ariya vehicle specification when replacing Electrically-driven Intelligent Brake Unit

SELF DIAGNOSTIC RESULT

Refer to DTC Index.

When “CRNT” is displayed on self-diagnosis result

  • The system is presently malfunctioning.

When “PAST” is displayed on self-diagnosis result

  • System malfunction in the past is detected, but the system is presently normal.

Freeze frame data (FFD)

When DTC is detected, a vehicle state shown below is recorded and displayed on CONSULT.

ACTIVE TEST

The active test is used to determine and identify details of a malfunction, based on self-diagnosis test result and data obtained in the Data monitor. In response to instructions from CONSULT, instead of those from Electrically-driven Intelligent Brake Unit on the Nissan Ariya vehicle, a drive signal is sent to the actuator to check its operation.

CAUTION:

  • Never perform Active test while driving the vehicle.

  • Always bleed air from brake system before active test.

  • Never perform active test when system is malfunctioning.

NOTE:

  • When performing active test again after “TEST IS STOPPED” is displayed, select “BACK”.

  • Brake warning lamp and brake system warning lamp may turn ON during active test. This is not a malfunction.

  • Perform all self-diagnosis and delete stored DTC after execute Active test.
