Qashqai J11. Drive Mode system — part 1

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precautions for Removing Battery Terminal

INFOID:0000000010521172

• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key

or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.

• When disconnecting the 12V battery terminal, turn off the ACC

power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.

• For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.

HOW TO DISCONNECT 12V BATTERY TERMINAL

Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.

INSTRUCTION 1

Open the hood.

< PRECAUTION >

[ECO MODE (CVT)]

Turn key switch to the OFF position with the driver side door opened.

Get out of the vehicle and close the driver side door.

Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

INSTRUCTION 2 (FOR VEHICLES PARKED BY IGNITION SWITCH OFF)

Unlock the door with intelligent key or remote keyless entry.
NOTE:
At this moment, ACC power is supplied.

Open the driver side door.

Open the hood.

Close the driver side door.

Wait at least 3 minutes.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

SYSTEM DESCRIPTION

NOTE:
When the ignition switch is turned ON while the ECO mode indicator lamp stays ON, the ECO mode indicator
lamp automatically turns ON at the next ignition switch ON.
• For except MR20DD engine models, TCM receives ECO mode switch signal (ON/OFF) from combination

meter via CAN communication. TCM transmits ECO mode indicator signal to combination meter via CAN
communication according to the signal. Combination meter illuminates ECO mode indicator lamp according
to the signal.

• For MR engine modes, TCM receive ECO mode switch signal (ON/OFF) from combination meter via CAN

communication. TCM transmits ECO mode signal to ECM via CAN communication according to the signal.

• For MR engine models, ECM transmits ECO mode indicator signal to combination meter via CAN communi-

cation. Combination meter illuminates ECO mode indicator lamp according to the signal.

• For details of TCM ECO mode control, refer to

TM-246, "ECO MODE CONTROL : System Description"

(RE0F10D), or

TM-460, "ECO MODE CONTROL : System Description"

(RE0F10G).

• For details of ECM ECO mode system (MR20DD engine models), refer to

ECM-50, "ECO MODE SYSTEM :

System Description"

TCM Control

When the ECO mode is ON, driving characteristic is controlled (for decreasing needless acceleration and
deceleration, reducing energy consumption, and fixing to ECO gear shift schedule), so that driving that
improves operational fuel efficiency is assisted.

ECM Control (MR20DD engine models)

ECM receives an ECO mode signal from TCM via CAN communication and improves the fuel economy by
controlling the throttle movement to less than usual.

GET INFORMATION FOR SYMPTOM

Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using the

TM-278, "Diagnostic Work Sheet"

[TCM (RE0F10D)],

TM-498,

"Diagnostic Work Sheet"

[TCM (RE0F10G)] or

ECM-123, "Diagnostic Work Sheet"

[ECM (MR20DD)].

>> GO TO 2.

CHECK DTC IN TCM AND ECM

Check DTC in TCM and ECM (MR20DD engine).

If a DTC is detected, perform the following steps, and after this, erase DTC.

Print (or write down) the detected DTC and freeze frame data.

Check DTC logic.

Study the relationship between the cause detected by DTC and the symptom described by the customer.

Check related Service Bulletins.

Are any symptoms described and any DTCs detected?

Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer.
Also study the normal operation and fail-safe related to the symptom. Refer to

TM-263, "Fail-safe"

[TCM

(RE0F10D)],

TM-478, "Fail-safe"

[TCM (RE0F10G)] or

ECM-87, "Fail-safe"

[ECM (MR20DD)].

Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 5.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer.
Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 6.

PERFORM DTC CONFIRMATION PROCEDURE

Perform DTC CONFIRMATION PROCEDURE for the displayed DTC, and then check that DTC is detected
again.
If two or more DTCs are detected, refer to

TM-266, "DTC Inspection Priority Chart"

[TCM (RE0F10D)],

TM-

484, "DTC Inspection Priority Chart"

[TCM (RE0F10G)] or

ECM-91, "DTC Inspection Priority Chart"

[ECM

(MR20DD)], and determine trouble diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service

Manual. This simplified check procedure is an effective alternative though DTC cannot be detected during
this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIR-
MATION PROCEDURE.

Is DTC detected?

YES

Check again, and then check that the malfunction have been completely repaired.
When symptom was described from the customer, refer to confirmed symptom in step 4 or 5, and check that
the symptom is not detected.
Is DTC detected and does symptom remain?

YES-1 >> DTC is detected: GO TO 7.
