*3: In Diagnostic Test Mode II (Self-diagnostic results), this number is controlled by NISSAN.
*4: Refer to EC-189, "Description"
.
*5: The troubleshooting for this DTC needs CONSULT.
*6: When the ECM is in the mode that displays SRT status, MIL may blink. For details, Refer to EC-74, "On Board Diagnosis Function"
.
*7: SRT code will not be set if the self-diagnostic result is NG.
*8: When the fail-safe operations for both self-diagnoses occur, the MIL illuminates.
*9: This self-diagnosis is not for ECM power supply circuit, even though “ECM BACK UP/CIRCUIT” is displayed on CONSULT screen.
Test Value and Test LimitINFOID:0000000009879628
The following is the information specif ied 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 disp layed 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)

HOW TO ERASE PERMANENT DTC
DescriptionINFOID:0000000009462146
OUTLINE
When a DTC is stored in ECM
When a DTC is stored in ECM and MIL is ON, a permanent
DTC is erased with MIL shutoff if the same mal-
function is not detected after performing the drivi ng pattern for MIL shutoff three times in a raw.
When a DTC is not stored in ECM
The erasing method depends on a permanent DTC stor ed in ECM. Refer to the following table.
NOTE:
If the applicable permanent DTC includes multiple groups, perform the procedure of Group B first. If the per-
manent DTC is not erased, per form the procedure of Group A.
×: Applicable —: Not applicable
*: For group, refer to EC-105, "DTC Index".
PERMANENT DTC ITEM
For permanent DTC items, MIL turns ON. Refer to EC-105, "DTC Index".
*1: When the same malfunction is de-
tected in two consecutive trips, MIL
will illuminate. *2: MIL will turn off after vehicle is driven
3 times (driving pattern B) without
any malfunctions.
