LINING THICKNESS INSPECTION
• Check thickness of lining.
DRUM INNER DIAMETER INSPECTION
• Check inner diameter of drum in rear disc rotor using a suitabletool.
OTHER INSPECTIONS
• Check the following:
- Lining for excessive wear, damage, and peeling.
- Shoe sliding surface for excessive wear and damage.
- Anti-rattle pin for excessive wear and corrosion.
- Return spring for sagging.
• Make sure that adjuster moves smoothly.
• Visually check the inside of drum for excessive wear, cracks, and damage.
• Replace with new parts as necessary.
Break-in ProcedureINFOID:0000000009462915
1. Perform parking brake break-in (drag run) operation by driving vehicle under the following conditions: • Drive the vehicle forward.
• Maintain vehicle speed at approximately 40 km/h (25 MPH) keeping it constant in forward direction.
• Apply the parking brake at the constant operating force specified. Approximately 200+49.0 Nm (20.4+5

Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951596
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009461595
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM
E/R sends a drive signal to the follo wing systems to check their operation.
• Front wiper (LO, HI)
• Front fog lamps
• Parking lamps
• Side marker lamps
• Tail lamps
• License plate lamps
• Daytime running lamps
• Headlamps (LO, HI)
• A/C compressor
• Cooling fans (LO, HI)
Operation Procedure
CAUTION:
Do not start the engine.
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
NOTE:
• If auto active test mode cannot be actuat ed, check door switch system. Refer to DLK-100,
"Component Function Check".
• When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
2. Turn ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press the front door switch LH 10 times. Then turn the ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once, and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following operation sequence is repeated 3 times.
*: Outputs duty ratio of 50% for 5 seconds → duty ratio of 100% for 5 seconds on the cooling fan control module.
Operation se-
quence Inspection Location Operation
1 Front wiper LO for 3 seconds → HI for 3 seconds

• Parking lamps
• Side marker lamps
•Tail lamps
• License plate lamps 10 seconds

Concept of auto active test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
Diagnosis chart in auto active test mode
CONSULT Function (IPDM E/R)INFOID:0000000009461602
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
