Diagnosis Description

APPLICATION ITEM

CONSULT performs the following functions by communicating with Li-ion battery controller (LBC).

X: Applicable

*: The following diagnosis information is erased when LBC memory is erased.

• DTC

• Freeze frame data (FFD)

SELF DIAGNOSIS RESULTS

• DTC Item

  • For the item “DTC and 1st trip DTC", Refer to DTC Index.

• How to read DTC and 1st trip DTC

  DTC and 1st trip DTC related to the malfunction are displayed on "Self Diagnostic Results" mode of CONSULT. "TIME" indicates the number of times the Nissan Ariya vehicle has been driven since the last DTC was detected.

  • If DTC is currently detected, the “TIME” is displayed as “0”.

  • When LBC stores 1st trip DTC, “TIME” is displayed as “1t”.

  • DTCs with “TIME” other than “0” or “1t” are defected that was occurred in the past.

• How to Erase DTC

  NOTE:

  If power switch remains ON after repair work, check that power switch in turned OFF.

  Then, wait for 10 seconds or more, and turn ON again.

  NOTE:

  Erase DTC in order first "HIGH VOLTAGE BATTERY 2" then next "HIGH VOLTAGE BATTERY".

  1. Select “HIGH VOLTAGE BATTERY 2” with CONSULT.

  2. Select “Self Diagnostic Results” mode.

  3. Touch “ERASE”. [DTC stored in LBC (Sub CPU) is erased.]

  4. Select “HIGH VOLTAGE BATTERY” with CONSULT.

  5. Select “Self Diagnostic Results” mode.

  6. Touch “ERASE”. [DTC stored in LBC (Main CPU) is erased.]
