*1: 1st trip DTC No. is the same as DTC No.
*2: These numbers are prescribed by SAE J2012.
*3: In Diagnostic Test Mode II (Self-diagnostic results), these numbers are controlled by NISSAN.
*4: When engine is running.
*5: The troubleshooting for these DTCs need CONSULT-II.
*6: When the fail-safe operations for both self-diagnoses occur, the MIL illuminates.
*7: CONSULT-II screen terms are shown differently depending on the version of CONSULT-II card.

NOTE:
Regarding Z50 models, "B1" indicates bank 1, "B2" indicates bank 2.
