PRECAUTIONS
Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
NEEL0001
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER" used along with a seat belt, help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and in the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness, and spiral cable. The vehicle (except Crew Cab model) is equipped with a passenger air bag deactivation switch. Because no rear seat exists where a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is enabled and could inflate in a frontal collision. When the switch is turned to the OFF position, the passenger air bag is disabled and will not inflate in a frontal collision. A passenger air bag OFF indicator on the instrument panel lights up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected by the passenger air bag deactivation switch. Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING: ¼ To avoid rendering the SRS inoperative, 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 should be performed by an authorized NISSAN dealer.
¼ 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 the RS section.
¼ Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. Spiral cable and wiring harnesses (except "SEAT BELT PRE-TENSIONER") covered with yellow insulation either just before the harness connectors or for the complete harness are related to the SRS.
¼ The vehicle (except Crew Cab model) is equipped with a passenger air bag deactivation switch which can be operated by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and will not inflate in a frontal collision. When the passenger air bag is switched ON, the passenger air bag is enabled and could inflate in a frontal collision. After SRS maintenance or repair, make sure the passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for service.

Wiring Diagrams and Trouble Diagnosis
When you read wiring diagrams, refer to the following: ¼ GI-11, "HOW TO READ WIRING DIAGRAMS" ¼ "POWER SUPPLY ROUTING" for power distribution circuit, EL-9 When you perform trouble diagnosis, refer to the following: ¼ GI-34, "How to Follow Test Groups in Trouble Diagnoses" ¼ GI-23, "HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT" Check for any Service bulletins before servicing the vehicle.

Coast Operation

NEEL0206S0203

When the COAST/SET switch is depressed during cruise control driving, ASCD motor actuator returns the throttle cable to decrease vehicle set speed until the switch is released. Then ASCD will keep the new set

speed.

If COAST/SET switch is pressed and released quickly during cruise control driving, vehicle set speed will be reduced by 1.6 km/h (1.0 MPH).

Accel Operation When the RES/ACCEL switch is depressed, ground is supplied

FE NEEL0206S0204

¼ from ASCD steering switch terminal 14

¼ to ASCD control unit terminal 11.

If the RES/ACCEL switch is depressed during cruise control driving, ASCD motor actuator pulls the throttle

cable to increase the vehicle speed until the switch is released or vehicle speed is reached to maximum con-

trolled speed by the system. Then ASCD will keep the new set speed.

If RES/ACCEL switch is pressed and released quickly during cruise control driving, vehicle set speed will be

increased by 1.6 km/h (1.0 MPH).
Cancel Operation When any of following conditions exist, cruise operation will be canceled

AT
NEEL0206S0205

¼ CANCEL switch is depressed. (Ground is supplied to ASCD control unit terminal 11)

¼ Brake pedal is depressed. (Power is supplied to ASCD control unit terminal 23 from stop lamp switch)

Brake or clutch pedal is depressed (M/T), brake pedal is depressed or A/T selector lever is shifted to P or N position (A/T). (Power supply to ASCD control unit terminal 8 is interrupted.)

If ON¼OFF switch is turned to OFF when ASCD is activated, all of ASCD operation will be canceled and vehicle

speed memory will be erased.

Resume Operation NEEL0206S0206
When the RES/ACCEL switch is depressed, after cancel operation other than depressing ON¼OFF switch is SU
performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must

meet following conditions

¼ Brake pedal is released.

¼ Clutch pedal is released (M/T).

¼ A/T selector lever is in other than P and N position (A/T). ¼ Vehicle speed is between 40 km/h (25 MPH) and 144 km/h (89 MPH).

ASCD MOTOR ACTUATOR OPERATION When the ASCD activates, power is supplied

RS NEEL0206S03

¼ from terminal 7 of ASCD control unit

¼ to ASCD motor actuator terminal 1, and

¼ from terminal 12 of ASCD control unit

¼ to ASCD motor actuator terminal 6.

Ground is supplied

¼ from ASCD control unit terminals 1, 13, and 14

¼ to terminals 3, 5, and 2 of ASCD motor actuator.

Power to the actuator motor is supplied constantly from the ASCD control unit. The ASCD control unit then

switches the actuator motor ground signals ON and OFF to control actuator motor operation and vehicle speed.

MULTI-REMOTE CONTROL SYSTEM
ID Code Entry Procedure (Cont'd)

NOTE:

¼ If a remote controller is lost, the ID code of the lost remote controller must be erased to prevent unautho-

rized use.

To erase all ID codes in memory, register one ID code (remote controller) four times. After all ID codes

are erased, the ID codes of all remaining and/or new remote controllers must be re-registered.
¼ When registering an additional remote controller, the existing ID codes in memory may or may not be MA

erased. If four ID codes are stored in memory when an additional code is registered, only the oldest code

is erased. If less than four ID codes are stored in memory when an additional ID code is registered, the

new ID code is added and no ID codes are erased.

¼ If you need to activate more than two additional new remote controllers, repeat the procedure "ADDI-

TIONAL ID CODE ENTRY" for each new remote controller. Entry of a maximum of four ID codes is allowed. When more than four ID codes are entered, the oldest

ID code will be erased.

¼ If an ID code has already been registered in the memory, the same ID code can be entered in the memory EC
again. Each registration of an ID code counts as an additional code.

Remote Controller Battery Replacement
NOTE:

AT NEEL0118

¼ Be careful not to touch the circuit board or battery terminal.

The remote controller is water-resistant. However, if it does get wet, wipe it dry immediately.

¼ After battery replacement, press the remote controller buttons

two or three times to check their operation.
