These instructions apply to the Nissan Armada Mk1 (TA60) 2004-2015.

After the battery has been off, the throttle body cleaned, or the electronic throttle serviced, the Nissan Armada (TA60, 2004–2015) and its 5.6-litre VK56DE V8 can idle roughly until the ECM relearns its settings. You can complete the full relearn yourself with no scan tool — it is an exact sequence of ignition and pedal moves.
Conditions That Must Be Met
The learn only takes if every one of these holds throughout; if one drops out even briefly it cancels:
- Battery above 12.9 V at idle.
- Coolant between 70 and 100 °C (158–212 °F).
- Transmission in P or N; steering straight; vehicle stopped.
- Air conditioning and headlights off.
- Transmission warmed — drive about 10 minutes first.
The Relearn Sequence
It is three learns performed in order. Time the steps with a clock.
- Accelerator-pedal released position: pedal fully up, ignition ON at least 2 seconds, OFF at least 10; ON again at least 2 seconds, OFF at least 10.
- Throttle-valve closed position: start cold (coolant below 25 °C/77 °F), warm past 65 °C (149 °F), then switch off and wait at least 10 seconds while the throttle valve cycles.
- Restart and bring the V8 to normal operating temperature, then confirm every condition above.
- Turn the ignition OFF and wait at least 10 seconds.
- Pedal fully released, turn the ignition ON and wait 3 seconds.
- Within 5 seconds, fully depress and fully release the accelerator five times.
- Wait 7 seconds, then hold the pedal flat for about 20 seconds until the malfunction lamp stops blinking and stays on.
- Release the pedal within 3 seconds of the lamp going steady.
- Start the engine, let it idle and wait 20 seconds.
- Rev two or three times and confirm the idle sits near 650 rpm in P or N.
If the Learn Fails
The usual culprit is a condition that slipped — a load switching on, coolant cooling below the window, or a timing that was off. Confirm the throttle valve closes fully, check for an intake leak, then run the sequence again from the start. A V8 that still idles poorly after a clean learn typically has a vacuum leak or a throttle body needing a proper clean.
Frequently Asked Questions
Do I need a scan tool? No — this is the no-tool method for the VK56DE.
When is it needed? After a battery disconnect or replacement, a throttle-body clean, or replacing the throttle actuator or ECM.
The warning lamp came on during the pedal steps. That is expected — it blinks then holds steady as a cue during the idle-air-volume step; it is not logging a fault.
What is the correct idle? Around 650 rpm (±50) in P or N, with ignition timing near 15° BTDC.
