Nissan Primera P12. Manual - part 212

ON BOARD DIAGNOSTIC (OBD) SYSTEM

EC-33

[YD (WITH EURO-OBD)]

*1: 1st trip DTC No. and 2nd trip DTC No. are the same as DTC No.
*2: This number is prescribed by ISO 15031-6.

DTC AND 1ST/2ND TRIP DTC

The number of 1st/2nd trip DTC is the same as the number of DTC.
When a malfunction is detected during 1st trip, 1st trip DTC is stored in the ECM memory. MI does not illumi-
nate at this time. When the same malfunction is detected in the next trip (2nd trip), 2nd trip DTC is stored in the
ECM memory and 1st trip DTC is cleared from the ECM memory. MI does not illuminate at this time. In addi-
tion, DTC is stored in the ECM memory and Mi lights up when the same malfunction is detected during the fol-
lowing consecutive trip (3rd trip).
The procedure for erasing DTC, 1st trip DTC, and 2nd trip DTC from the ECM memory is described in

EC-34,

"HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION"

For malfunctions in which 1st/2nd trip DTC are displayed, Refer to

EC-31, "Emission-related Diagnostic Infor-

mation"

1st/2nd trip DTC is specified in Mode 7 of ISO15031-5. 1st/2nd trip DTC detection occurs without lighting up
MI and therefore does not warn the driver of a malfunction.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

When 1st/2nd trip DTC is detected, check, print out or write down, and erase 1st/2nd trip DTC as specified
with step II of Work Flow, refer to

EC-41, "WORK FLOW"

. Then perform DTC Confirmation Procedure or

Overall Function Check to try to duplicate the malfunction. If the malfunction is duplicated, it is necessary to
investigate the cause again.

How to Read DTC and 1st/2nd Trip DTC

DTC and 1st/2nd trip DTC can be read by the following procedures.

With CONSULT-II
With GST

ONSULT-II or GST (Generic Scan Tool): Examples: P0117, P0335, P1260, etc.
These numbers are prescribed by ISO 15031-6.
(CONSULT-II also displays the malfunctioning parts and systems.)
A sample of CONSULT-II display for DTC and 1st/2nd trip DTC is
shown in the figure. DTC and 1st/2nd trip DTC are displayed in the
“SELF-DIAG RESULTS” mode of CONSULT-II.
“TIME” data shows how many times the vehicle was driven after the
last detection of DTC or 1st/2nd trip DTC. When DTC or 1st/2nd trip
DTC has been detected currently, “TIME” becomes “0”.

●

CONSULT-II displays for DTC and 1st/2nd trip DTC become the
same.

●

The output of a DTC indicates a malfunction. However, GST
does not indicate whether the malfunction is still occurring or
has occurred in the past and has returned to normal. CONSULT-
II can identify the malfunction status. Therefore the use of CON-
SULT-II (If available) is recommended.

FREEZE FRAME DATA

ECM records 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 DTC is called Freeze Frame Data, and is displayed on CONSULT-II or GST.
When 1st/2nd trip DTC is detected, Freeze Frame Data is not recorded.
Only a set of Freeze Frame Data can be stored in the ECM memory. When ECM records Freeze Frame Data,
and another Freeze Frame Data is generated after that, the first (original) Freeze Frame Data is not updated in
ECM and it remains.
When the DTC is erased from ECM memory, Freeze Frame Data is erased with DTC. The procedure for eras-
ing DTC is described in

EC-34, "How to Erase DTC"

HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION
How to Erase DTC

With CONSULT-II

The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
1.

If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.

Touch “ENGINE”.

Touch “SELF-DIAG RESULTS”.

PBIB2022E

ON BOARD DIAGNOSTIC (OBD) SYSTEM

EC-35

[YD (WITH EURO-OBD)]

Touch “ERASE”. (The DTC in the ECM will be erased.)

With GST

The emission related diagnostic information in the ECM can be erased by selecting MODE 4 with GST.

If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.

Select MODE 4 with GST (Generic Scan Tool).

●

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

–

2nd trip diagnostic trouble codes

–

Freeze frame data

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)

EBS013JG

●

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 NATS (Nissan Anti-Theft System) in BL section.

●

Confirm no self-diagnostic results of NATS is displayed
before touching "ERASE" in "SELF-DAIG 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 procedure of NATS initialization and NATS ignition key ID registration, refer to CON-
SULT-II operation manual, NATS.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Malfunction Indicator (MI)

EBS013JH

DESCRIPTION

The MI is located on the instrument panel.

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-84, "WARNING LAMPS"

or see

EC-347

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 two functions.

Diagnostic Test Mode I - Bulb Check

In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to

DI-84,

"WARNING LAMPS"

or see

MALFUNCTION
WARNING

This 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.

Condition
