INSTALLATION
NOTE:
The figure shows the relationship between the mating mark on each
timing chain and that on the corresponding sprocket, with the com-
ponents installed.
1. Make sure that crankshaft key points straight up.
2. Tighten mounting bolts in numerical order as shown in figure
with the following procedure, and install balancer unit.
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer to EM-48, "
INSPECTION AFTER
REMOVAL" .
a. Apply new engine oil to threads and seat surfaces of mounting
bolts.
b. Tighten all bolts.
c. Turn all bolts 90 degrees clockwise (angle tightening).
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order as shown in the
figure.
e. Tighten all bolts.
f. Turn them another 90 degrees clockwise (angle tightening).
CAUTION:
Check tightening angle with an angle wrench (special service tool) or a protractor. Do not make
judgment by visual check alone.

2. Perform AT- 4 3 , "HOW TO ERASE DTC (WITH GST)" . (The DTC in the TCM will be erased.)
3. Select MODE 4 with GST (Generic Scan Tool).
No Tools
NOTE:
If the DTC is not for A/T related items (see EC-19
), skip step 2.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once.
Wait at least 10 seconds and then turn it ON (engine stopped) again.
2. Perform AT- 4 3 , "
HOW TO ERASE DTC (NO TOOLS)" . (The DTC in TCM will be erased.)
3. Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to
EC-66, "
HOW TO SWITCH DIAGNOSTIC TEST MODE" .

If the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.

The following data are cleared when the ECM memory is erased.
–Diagnostic trouble codes
–1st trip diagnostic trouble codes
–Freeze frame data
–1st trip freeze frame data
–System readiness test (SRT) codes
–Test values
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures.
NATS (Nissan Anti-theft System)EBS010LM

If the security indicator lights up with the ignition switch in
the ON position or “NATS MALFUNCTION” is displayed on
“SELF-DIAG RESULTS” screen, perform self-diagnostic
results mode with CONSULT-II using NATS program card.
Refer to BL-108, "
NATS (NISSAN ANTI-THEFT SYSTEM)" .

Confirm no self-diagnostic results of NATS is displayed
before touching “ERASE” in “SELF-DIAG RESULTS” mode
with CONSULT-II.

When replacing ECM, initialization of NATS system and reg-
istration of all NATS ignition key IDs must be carried out
with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedures of NATS initialization and all NATS ignition key ID registration, refer to
CONSULT-II Operation Manual, NATS.
Malfunction Indicator (MI)EBS010LN
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
If the MI does not light up, refer to DI-33, "
WARNING LAMPS"
or see EC-469 .
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following four functions.
