OK or NG
OK >> GO TO 4.
NG >> Check combination meter circuits.
4.CHECK 4WD AUTO LAMP (ON COMBINATION METER) CIRCUIT
Check continuity between combination meter terminal 46 (LHD models) or 59 (RHD models) and terminal 18.
OK or NG
OK >> Using CONSULT-II perform self-diagnosis.
NG >> Check for burned-out bulb in 4WD AUTO lamp.18 (YG) - 16 (Y/G) : Continuity should exist.

Check for continuity between the power supply terminal of meter and terminal of ABS warning lamp.
Is inspection result OK?
OK >> GO TO 2.
NG >> Circuit malfunction in SLIP indicator lamp or combination meter
2.SLIP INDICATOR LAMP POWER CIRCUIT INSPECTION
Disconnect the meter connector. Check that the voltage between the vehicle-side harness terminal and body
ground is battery voltage (Approx. 12V).
Is inspection result OK?
YES >> GO TO 3.
NO >>
lFuse inspection
lInspection for harness and connectors between fuse block and meter
lCheck the power supply circuit (battery and ignition switch circuit).
3.SLIP INDICATOR LAMP HARNESS INSPECTION
1. Disconnect connectors for the ESP/TCS/ABS control unit and meter vehicle-side harness.
2. Check the harness between the meter and the ESP/TCS/ABS control unit for an open/shorted circuit.
Is inspection result OK?
OK >> GO TO 4.
NG >> Repair or replace the disconnected harness.
4.SLIP INDICATOR LAMP CONNECTOR INSPECTION
Check connectors for the ESP/TCS/ABS control unit and meter vehicle-side harness.
Is inspection result OK?
YES >> Connect connectors, and perform the self-diagnosis. The vehicle harness has the intermediate
connector. Refer to the vehicle wiring diagram, always check it.
NG >> Repair or replace the disconnected connector.
Symptom 8: During ESP/TCS/ABS Control, Vehicle Behavior is Jerky.EFS001AZ
Inspection procedure
1.ENGINE SPEED SIGNAL INSPECTION
Perform²DATA MONITOR²with CONSULT-II for the ESP/TCS/ABS control unit.
Is the engine speed at idle 400 rpm or higher?
YES >> Normal
NO >> GO TO 2.
2.SELF-DIAGNOSIS RESULT CHECK 1
Perform the ESP/TCS/ABS control unit self-diagnosis.
Is the self-diagnosis results displayed?
YES >> After checking and repairing the applicable item, perform the ESP/TCS/ABS control unit self-
diagnosis again.
NO >> GO TO 3.

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)EBS00BM8
lIf 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 toBL-70, "
NATS (NISSAN ANTI-THEFT SYSTEM)".
lConfirm no self-diagnostic results of NATS is displayed
before touching “ERASE” in “SELF-DIAG RESULTS” mode
with CONSULT-II.
lWhen 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 NATS ignition key ID registration, refer to
CONSULT-II operation manual, NATS.
Malfunction Indicator (MI)EBS00BM9
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.
lIf the MI does not light up, refer toDI-39, "WARNING LAMPS",
or seeEC-252
.
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.

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.
