*1: 1st trip DTC No. is the same as DTC No.
*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:Refer to 

EC-601, "Description"

, “PERMANENT DIAGNOSTIC TROUBLE CODE (PERMANENT DTC)”.

*5: The troubleshooting for this DTC need CONSULT.
*6: When the ECM is in the mode of displays SRT status, MIL may blink. For the details, refer to “How to Display SRT Status”.
*7: SRT code will not be set if the self-diagnostic result is NG.
*8: When erasing this DTC, always use CONSULT or GST.

Test Value and Test Limit

INFOID:0000000010232194

The following is the information specified in Service $06 of SAE J1979/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 displayed with GST screen which items are provided by the

ECM. (e.g., if bank 2 is not applied on this vehicle, only the items of bank 1 are displayed)
