Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO procedure 3²CHECK WHEEL SENSOR AND SENSOR ROTOR²of symptom 1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
Symptom 6: ABS Warning Lamp Indication Is Not NormalEFS005UD
NOTE:
Lighting condition of ABS warning lamp refer toBRC-24, "
BASIC INSPECTION 3 ABS WARNING LAMP AND
BRAKE WARNING LAMP INSPECTION".
1.CHECK COMBINATION METER INDICATION
Check the combination meter indication and operation. Refer toDI-13, "

EC-28
ON BOARD DIAGNOSTIC (OBD) SYSTEM
lIf the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.
lThe following data are cleared when the ECM memory is erased.
–Diagnostic trouble codes
–Freeze frame data
–Fuel pump learning value
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.
Freeze Frame DataEBS01KCP
The ECM records the driving conditions such as calculated load value, engine coolant temperature, engine
speed, vehicle speed and intake manifold pressure at the moment a malfunction is detected.
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II. For
details, seeEC-28, "
Freeze Frame Data".
Only one set of freeze frame data can be stored in the ECM. If freeze frame data is stored in the ECM memory
and another freeze frame data occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clear-
ing the ECM memory are described inEC-27, "
HOW TO ERASE DTC".
NATS (Nissan Anti-theft System)EBS01KCQ
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-170, "
NATS(Nissan Anti-Theft System)".
lConfirm no self-diagnostic results of NATS is displayed
before touching "ERASE" in "SELF-DAIG 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 procedure of NATS initialization and NATS ignition key ID registration, refer to CON-
SULT-II operation manual, NATS.
Malfunction Indicator (MI)EBS01KCR
DESCRIPTION
The MI is located on the combination meter.
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 toEC-354, "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 three functions.

HOWTOSWITCHDIAGNOSTICTESTMODE
NOTE:
lIt is better to count the time accurately with a clock.
lIt is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit
has a malfunction.
lAlways ECM returns to Diagnostic Test Mode I after ignition switch is turned OFF.
How to Set Diagnostic Test Mode II (Self-diagnostic Results)
1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MI starts
blinking.
4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).

circuit, etc.).
If the MI does not come on, check MI circuit. (SeeEC-354,

WARNINGThis is a usual driving condition. When ECM detects a mal-
function, the MI will light up to inform the driver that a mal-
function has been detected.

TROUBLE DIAGNOSIS
Basic Inspection
EBS01KCV
Precaution:
Perform Basic Inspection without electrical or mechanical loads applied;
lHeadlamp switch is OFF.
lOn vehicles equipped with daytime light systems, set lighting switch to the 1st position to light
only small lamps.
lAir conditioner switch is OFF.
lHeater fan switch is OFF.
lRear defogger switch is OFF.
lHeat up switch is OFF.
lSteering wheel is in the straight-ahead position, etc.
1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related incident.
2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to
MA-8, "
PERIODIC MAINTENANCE".
3. Open engine hood and check the following:
–Harness connectors for improper connections
–Vacuum hoses for splits, kinks, or improper connections
–Wiring for improper connections, pinches, or cuts
4. Start engine and warm it up to the normal operating tempera-
ture.
>> GO TO 2.
2.PREPARATION FOR CHECKING IDLE SPEED
With CONSULT-II
Connect CONSULT-II to the data link connector.
Without CONSULT-II
Install diesel tacho tester to the vehicle.
>> GO TO 3.
