Basic Maintenance Procedures — Basic Checks (Nissan Note E11)

1. Start the check

1. Check whether there are any entries in the service log for recently performed repairs that could indicate the corresponding malfunction, and whether the scheduled maintenance is due.

2. Open the hood and check the following:

• are the electrical wiring connectors tightly connected?;
• are the wiring harnesses laid correctly, not pinched or cut?;
• are the vacuum hoses tightly connected, pinched, or cracked?;
• are there any leaks from the hoses and tubes;
• is the air purifier clogged?;
• gasket.

3. Make sure that electrical consumers are disconnected and there are no mechanical loads.

• headlights off;
• the air conditioner is off;
• rear window defroster off;
• the steering wheel is in a position corresponding to straight-line movement, etc.

4. Start the engine and warm it up until the engine coolant temperature gauge needle moves to the middle of the scale.



Make sure the engine speed is below 1000 rpm.

5. Let the engine run at about 2000 rpm for about 2 minutes without load.



6. Using the CONSULT-II tester or GST scanner, make sure that no DTC codes are displayed.

Normal or abnormal
Normal - Proceed to step 3.
Abnormal - Proceed to step 2.

2. Repair or replace

Repair or replace components according to the appropriate "Diagnostic Procedure". Go to step 3.

3. Check the specified idle speed.

1. Let the engine run at about 2000 rpm for about 2 minutes without load.



2. Increase the engine speed two or three times (from 2000 to 3000 rpm) without load, then let the engine run at idle speed for 1 minute.



3. Check the idle speed.

Automatic transmission: 700±50 rpm (in position "P" or "N")
Manual transmission: 650±50 rpm (in neutral position)

Normal or abnormal
Normal - Proceed to step 10.
Abnormal - Proceed to step 4.

4. Conduct accelerator pedal release position training

1. Turn off the engine.

2. Perform the released accelerator pedal position training. Go to step 5.

5. Conduct closed throttle position training

Conduct closed throttle position training. Proceed to step 6.

6. Conduct training on air supply at idle speed.

See section "Training in air supply at idle speed."

Was the idle air supply training successful?

Yes or no
Yes - Proceed to step 7.
No -

• 1. Follow the instructions in the section "Training in air supply at idle speed."
• 2. Proceed to step 4.

7. Check the specified idle speed again.

1. Start the engine and warm it up to normal operating temperature.

2. Check the idle speed.

Automatic transmission: 700±50 rpm (in position "P" or "I")
Manual transmission: 650±50 rpm (in neutral position)



Normal or abnormal
Normal - Proceed to step 10.
Abnormal - Proceed to step 8.

8. Identify the faulty component

Check the following:

• Camshaft Position Angle Sensor (PHASE) and Circuit.
• Crankshaft Position Sensor (POS) and circuit.

Normal or abnormal
OK - Proceed to step 9.
It's not normal -

• 1. Repair or replace
• 2. Proceed to step 4.

9. Check the operation of the ECM unit

1. To check the operation of the ECM, replace it with a known good unit (The ECM may be the cause of the problem, although this is unlikely).

2. Initialize the NATS system and register the identification codes of all NATS ignition keys. Go to step 4.

10. Check the ignition timing

1. Let the engine run at idle speed.

2. Check the ignition timing angle using a stroboscope.

Automatic transmission: 6±5° before TDC (in position "P" or "N")
Manual transmission: 6±5° before TDC (in neutral position)

Normal or abnormal
Normal - END OF CHECK
Abnormal - Proceed to step 11.



1. Synchronization pointer

11. Conduct accelerator pedal release position training

1. Turn off the engine.

2. Perform the released accelerator pedal position training. Go to step 12.

12. Conduct closed throttle position training

Conduct closed throttle position training. Proceed to step 13.

13. Conduct training on air supply at idle speed.

See section "Training in air supply at idle speed.".

Was the idle air supply training successful?

Yes or no
Yes - Proceed to step 14.
No -

• 1. Follow the instructions in the section "Training for air supply at rpm x x.".
• 2. Proceed to step 4.

14. Check the specified idle speed again.

1. Start the engine and warm it up to normal operating temperature

2. Check the idle speed.

Automatic transmission: 700±50 rpm (in position "P" or "N")
Manual transmission: 650±50 rpm (in neutral position)

Normal or abnormal
OK - Proceed to step 15.
Abnormal - Proceed to step 17.

15. Check the ignition timing again

1. Let the engine run at idle speed.

2. Check the ignition timing angle using a stroboscope.



1. Synchronization pointer

Automatic transmission: 6±5° before TDC (in position "P" or "N")
Manual transmission: 6±5° before TDC (in neutral position)

Normal or abnormal
Normal - END OF CHECK
Abnormal - Proceed to step 16.

16. Check the timing chain installation

Check the timing chain installation. See chapter Mechanical part of the engine.

Normal or abnormal
OK - Proceed to step 17.

It's not normal -

• 1. Correct timing chain installation defects
• 2. Proceed to step 4.

17. Identify the faulty component

Check the following:

• Camshaft Position Angle Sensor (PHASE) and Circuit.
• Crankshaft Position Sensor (POS) and Circuit

Normal or abnormal
Normal - Proceed to step 10.
It's not normal -

• 1. Repair or replace.
• 2. Proceed to step 4.

18. Check the operation of the ECM unit

1. To check the operation of the ECM, replace it with a known good unit (The ECM may be the cause of the problem, although this is unlikely).

2. Initialize the NATS system and register the identification codes of all NATS ignition keys. Go to step 4.
