Nissan Armada 2025-2026 Service and Repair Manual: How to Set Srt Code

SRT Set Driving Pattern

CAUTION:

Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

*1: Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then release the accelerator pedal and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again.

*2: Checking the vehicle speed with GST is advised.

• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.

  Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the shortest.

  Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed within zone A.

*: Normal conditions refer to the following:

• Sea level

• Flat road

• Ambient air temperature: 20 – 30°C (68 – 86°F)

NOTE:

Diagnosis is performed as quickly as possible under normal conditions. However, under other conditions, diagnosis may also be performed. [For example: ambient air temperature other than 20 – 30°C (68 – 86°F)]

Description

How to Erase Permanent Dtc

Description

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 malfunction is not detected after performing the driving pattern for MIL shutoff three times in a raw.

*1:

When the same malfunction is detected in two consecutive trips, MIL will illuminate.

*2:

MIL will turn off after vehicle is driven 3 times (pattern B) without any malfunctions.

When a DTC is not stored in ECM

The erasing method depends on a permanent DTC stored 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 permanent DTC is not erased, perform the procedure of Group A.

×: Applicable —: Not applicable

Group *	Perform “DTC CONFIRMATION PROCEDURE” for applicable DTCs.	Driving pattern
		B	D
A	×	—	—
B	—	×	×

*: For group, Refer to DTC Index.

Permanent DTC item

For permanent DTC items, MIL turns ON. Refer to DTC Index.
