*2: This number is prescribed by SAE J2012/ISO 15031-6.
*3: In Diagnostic Test
Mode II (Self-diagnostic results), this number is controlled by NISSAN.
*4: The troubleshooting for this DTC needs CONSULT-III.
*5: When the fail safe operations for both self-diagnoses occur, the MIL illuminates.
*6: When the ECM is in the mode that displays SRT status, MIL may blink. For the details, refer to “How to Display SRT Status”.
*7: When erasing this DTC, al ways use CONSULT-III or GST.
*8: SRT code will not be set if the self-diagnostic result is NG.
Test Value and Test LimitINFOID:0000000006217734
The following is the information specified in Service $06 of ISO 15031-5.
The test value is a parameter used to determine whether a system/circuit diagnostic test is OK or NG while
being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the
maximum or minimum value and is compared with the test value being monitored.
These data (test value and test limit) are specified by On Board Monitor ID (OBDMID), Test ID (TID), Unit and
Scaling ID and can be displayed on the GST screen.
The items of the test value and test limit will be di splayed with GST screen which items are provided by the
ECM. (e.g., if bank 2 is not applied on this v ehicle, only the items of bank 1 are displayed)
