Audible Warnings Description and Operation
The audible warnings alert the driver of a system concern or a critical vehicle condition. The instrument panel cluster (IPC) generates audible warnings through an internal acoustic speaker. The IPC receives audible warning requests via the serial data circuit. If the IPC receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
Fast rate chime (200 pulses per minute)
Medium rate chime (150 pulses per minute)
Slow rate chime (50 pulses per minute)
Single chime
Door Ajar Warning
The IPC activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The door ajar warning sounds and the appropriate DOOR AJAR indicator illuminates in the driver information center (DIC) when the following occurs:
• The body control module (BCM) determines that a door, driver door, passenger door. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The vehicle is not in park. The IPC receives a serial data message from the BCM indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 MPH). The IPC uses the vehicle speed information from the ECM to calculate the vehicle speed.

Audible Warnings Circuit Description
Safety Belt Warning Chime
Voltage is supplied to the body control module (BCM) through the following components when the ignition switch is in the START or RUN position:
• The GAUGES fuse 4
• CKT 39 (PNK)
When you first turn the ignition switch to the START or RUN position, a class 2 signal from the BCM is sent to the instrument cluster logic turning ON the fasten seat belt indicator. The indicator comes on steady for 20 seconds and then flashes for another 55 seconds if the drivers safety belt remains unbuckled, or goes out when the drivers safety is buckled. When the drivers safety belt is buckled, ground is no longer applied to the BCM through CKT 238 (BLK/WHT) from the seat belt switch causing the lamp and chime to go out. The chime will only sound for about the first 5 seconds of the ignition on cycle.
Key-In Warning Chime
Voltage is supplied at all times to the BCM through the following components:
• The Underhood Fuse Block TBC fuse
• CKT 1140 (ORN)
The chime sounds if all of the following conditions exist:
• The key is in the ignition switch.
• The ignition switch is in one of the following positions:
- ACC
- LOCK
- OFF
• The LH front door is open.
When the ignition key is in the ignition switch and the LH front door is open, the ignition key alarm switch closes. The LH door jamb switch also closes. When both of the switches close, the Body Control Module (BCM) senses ground through the following components:
• CKT 126 (TAN)
• The LH Door Jamb Switch
• CKT 1050 (BLK)
• SP203
• C203 cavity F12
• G203
The chime will sound for as long as the door is open and the key is in the ignition switch.
Lamps-On Warning Chime
Voltage is supplied through the ILLUM Fuse 12 to the BCM through CKT 1220 (GRY) when the following conditions exist:
• The headlamp switch is in the PARK or Head position
• The ignition switch is not in the RUN or START position
• The IP dimmer switch is not at the dimmest setting.
With the IP dimmer switch at the dimmest setting, the current to the BCM may be too weak to be sensed by the module. When the ignition switch is turned to the RUN or START position, voltage is supplied from the GAUGES Fuse 4 to the body control module through CKT 39 (PNK). When the ILLUM and GAUGES Fuse voltages are sensed at the same time, the alarm is not sounded. The GAUGES Fuse 4 loses voltage when the ignition switch is in one of the following positions:
• LOCK
• OFF
• ACC
I'am assuming the chime stays on all the time .

According to the Nissan service manual the procedure to Reset the Air Bag System Warning Light is as follows:
1. Turn ignition switch from OFF to ON.
2. Air Bag warning light is on for 7 seconds and turns off, turn the ignition switch OFF within 1 second after the light goes out.
3. After ignition switch is turned OFF, wait for more than 3 seconds.
4. Repeat steps 1 to 3 twice. (Perform 3 times in total.)
5. Turn Ignition switch ON.
6. The SRS light should be reset.
If the warning light can not be reset I'd suggest you contact your Nissan dealer for more information and a proper diagnostics check as there be a fault with the airbag system.

If no warning if u driving - is all ok! Do not worry!
If you driving and comse up some warnings then is better drive to service.

install a mechanical guage to test the actual pressure, if its fine the sending unit is faulty, if nor remove the oil pan and check the oil pickup for blockage,

Have no clue as to what you want ? Like to try an explain a little better . What do DTC'S 740 , 785 and 1860 have to do with key in ignition chimes . Plus i'am assuming the DTC'S you have listed all start with P - P0740 , P0785 and P1860 .
DTC P0740 TCC Enable Solenoid Circuit Electrical (2.2L)
DTC P0740 TCC Enable Solenoid Circuit Electrical (4.3L)
DTC P0785 3-2 Shift Solenoid Circuit Electrical (2.2L)
DTC P0785 3-2 Shift Solenoid Circuit Electrical (4.3L)
DTC P1860 TCC PWM Solenoid Circuit Electrical (2.2L)
DTC P1860 TCC PWM Solenoid Circuit Electrical (4.3L)

None of these have anything to do with warning chimes .

Key-In Warning Buzzer
Voltage is supplied at all times to the truck BCM through the following components:
• The underhood bussed electrical center (UBEC) fuse 4
• CKT 1140 (ORN)
The chime or buzzer sounds if the following conditions exist:
• The key is in the ignition switch
• The vehicle is not running.
• The left door is open.
When the door is open, the LF door jamb switch closes to ground. This provides a ground to the truck BCM through the following components:
• CKT 126 (TAN)
• The left front side door jamb switch
• CKT 1050 (BLK)
• SP203
• C203, cavity F12
• G203
The chime or the buzzer will sound for as long as the door is open and the key is in the ignition switch.

Your best bet take to a qualified repair shop

You can disconnect your battery for 15 minutes or pull the fuse for an ECM or PCM fuse, but the best way is to visit any local repair shop. Most shops will have a universal Check Engine Light Code Reader that can quickly and safely reset check engine light trouble codes. It should take about 30 seconds.

Ask your local service center if they could reset the check engine light with a Check Engine Light Code Reader.

Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.

• The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.

Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
