NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)
Revision: 2006 November2007 350Z
NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)PFP:25386
DescriptionNBS0002Y
If the security indicator lights up with the ignition switch in the ON position or “NATS MALFUNC-
TION” is displayed on “SELF-DIAG RESULTS” screen, perform self-diagnostic results mode with
CONSULT-III using NATS program card. Refer to BL-150, "
NVIS (NISSAN VEHICLE IMMOBILIZER
SYSTEM-NATS)" .
Confirm no self-diagnostic results of NVIS (NATS) is displayed before touching “ERASE” in
“SELF-DIAG RESULTS” mode with CONSULT-III.
When replacing ECM, initialization of NVIS (NATS) system and registration of all NVIS (NATS) igni-
tion key IDs must be carried out with CONSULT-III using NATS program card.
Therefore, be sure to receive all keys from vehicle owner. Regarding the procedures of NVIS
(NATS) initialization and all NVIS (NATS) ignition key ID registration, refer to CONSULT-III Opera-
tion Manual, IVIS/NVIS.

7. CHECK TARGET IDLE SPEED AGAIN
With CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Read idle speed in “DATA MONITOR” mode with CONSULT-III.
Refer to EC-76, "
IDLE SPEED" .
Without CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Check idle speed. Refer to EC-76, "
IDLE SPEED" .
OK or NG
OK >> GO TO 10.
NG >> GO TO 8.
8. DETECT MALFUNCTIONING PART
Check the following.
Check camshaft position sensor (PHASE) and circuit.
Refer to EC-394, "
DTC P0340, P0345 CMP SENSOR (PHASE)" .
Check crankshaft position sensor (POS) and circuit.
Refer to EC-386, "
DTC P0335 CKP SENSOR (POS)" .
OK or NG
OK >> GO TO 9.
NG >> 1. Repair or replace.
2. GO TO 4.
9. CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM function. (ECM may be the cause of an incident, but
this is a rare case.)
2. Perform initialization of NVIS (NATS) system and registration of all NVIS (NATS) ignition key IDs.
Refer to BL-150, "
NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)" .
>> GO TO 4.
10. CHECK IGNITION TIMING
1. Run engine at idle.
2. Check ignition timing with a timing light.
Refer to EC-76, "
IGNITION TIMING" .
OK or NG
OK >> GO TO 19.
NG >> GO TO 11.A/T: 650 ± 50 rpm (in P or N position)
M/T: 650 ± 50 rpm (in Neutral position)
A/T: 650 ± 50 rpm (in P or N position)
M/T: 650 ± 50 rpm (in Neutral position)
A : Timing indicator
A/T: 15 ± 5° BTDC (in P or N position)
M/T: 15 ± 5° BTDC (in Neutral position)
