DISASSEMBLY
1. Remove engine, transaxle and transfer assembly from the vehicle, then separate engine and transaxle
and transfer assembly. Refer to EM-222, "
ENGINE ASSEMBLY" .
2. Remove clutch cover and disk. Refer to CL-16, "
CLUTCH DISC, CLUTCH COVER AND FLYWHEEL" .
3. Install engine to engine stand as follows:
a. Remove flywheel.
b. Secure ring gear with the ring gear stopper (special service
tool), then loosen mounting bolts with TORX socket (size: T55,
Commercial Service Tools) and remove them. As an alternative
method hold crankshaft pulley with the pulley holder (special
service tool: KV10109300) to remove flywheel.
CAUTION:

Do not disassemble flywheel.

Do not place flywheel with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
c. Install the engine sub-attachment (special service tool) to the
rear side of cylinder block.

Align knock pins on cylinder block with pin holes on attach-
ment to install.
NOTE:
Installation bolts are part of engine sub-attachment.
d. Install the engine stand shaft (special service tool).
NOTE:
Use commercially available M12 (0.47 in) mounting bolts and
nuts (4 sets) with strength grade of 9T (minimum).

2. Perform AT- 4 3 , "HOW TO ERASE DTC (WITH GST)" . (The DTC in the TCM will be erased.)
3. Select Service $04 with GST (Generic Scan Tool).
No Tools
NOTE:
If the DTC is not for A/T related items (see EC-19, "
INDEX FOR DTC" ), 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-35, "
WARNING LAMPS"
or see EC-518, "MI & DATA LINK CONNECTORS" .
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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
EC-65

EC

When there is an open circuit on MI circuit, the ECM can not warn the driver by lighting up MI when there is
trouble on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine control system has trouble and MI circuit is open by means of
operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI circuit are detected and demands the
driver to repair the trouble.
MI Flashing without DTC
If the ECM is in Diagnostic Test Mode II, MI may flash when engine is running. In this case, check ECM diag-
nostic test mode. EC-66, "
HOW TO SWITCH DIAGNOSTIC TEST MODE" .
How to switch the diagnostic test (function) modes, and details of the above functions are described later, EC-
66, "HOW TO SWITCH DIAGNOSTIC TEST MODE" .
The following emission-related diagnostic information is cleared when the ECM memory is erased.

WARNINGThis is a usual driving condition. When a malfunction is
detected twice in two consecutive driving cycles (two trip
detection logic), the MI will light up to inform the driver that
a malfunction has been detected.
The following malfunctions will light up or blink the MI in
the 1st trip.
