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 .

The warning chime sounds if the parking lamps (13200) or the headlamps (13008) are left on after the key has been removed from the ignition switch lock cylinder and either front door (20124) is opened. There is a chime module that controls this .
The safety belt warning chime (10D840) (also called the central processing unit or CPU) is an audible warning system and timing circuit. The system components include:

• Timing circuit safety belt switch.
• Dome lamp switches.
• Safety belt warning indicator switch which is an integral part of the front safety belt buckle end (61203).
• Ignition switch (11572).
• Headlamp switch.

The warning chime sounds and the safety belt warning indicator illuminates when the ignition switch is placed in the ON position and the LH front safety belt is not buckled.
Key In Ignition Warning
The warning sounds if the key is left in the ignition switch lock cylinder when either door is opened and the ignition switch is in the LOCK or OFF position.
Don't any of chimes work ?

• The Headlamp on Reminder Chime Is Inoperative/Does Not Operate Properly

• Circuits.
• Fuse junction panel.
• Warning chime module.

• GO to Pinpoint Test D .

Let me know ,mite work this out !
Don't

Check all your fuses. Check the door jam switch. I Had a Volvo do that once and the brake light fuse was bad which caused the chime to ding all the time. When you open the door with the key in ign the ding goes off. I would check that switch and circuit if the fuses are ok

How about a year, make, model? They're all wired differently

Do the interior lights come on when door is open? If not, you need to check driver's door jamb switch. The driver's door control module could also be the problem. If the interior light do come on, then I would suspect the ignition switch.
You haven't changed out the radio recently? All chimes go thru the radio.

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.

Warning Chime Systems The generic electronic module (GEM) will sound the following warnings:

• key-in-ignition warning
• safety belt warning
• headlamp switch ON warning
• door ajar warning

------------------------------------------------------------------------------------------------
Headlamp Switch On Warning The generic electronic module (GEM) sounds when the driver door is opened while the headlamp switch (11654) is in the PARK or HEAD position, and continues to sound at a rate of 4 chimes per second until the headlamp switch is turned off or the driver door is closed.

• When the headlamp switch is in the PARK or HEAD position, power is supplied through Circuit 293 (O/R) to the GEM.
• When the driver door is open, the driver door open warning lamp switch (10B997)is closed and ground is supplied to the generic electronic module (GEM).

A delayed headlamps on repetitive chime will sound for a period of three seconds beginning twenty seconds after the key is turned to OFF, LOCK or ACC, the headlamp switch is in the PARK or HEAD position, and the driver door is closed. Delayed headlamps on is terminated by opening and closing the driver door again.
---------------------------------------------------------------------------------------
Door/Liftgate Ajar Warning The door/liftgate ajar warning functions as follows:

• The generic electronic module (GEM) sounds a warning tone for one second when any vehicle door, liftgate window or the liftgate is ajar without any other door already open and the ignition switch is in the RUN position.
• Power is then supplied through Circuit 627 (BK/O) to the door ajar warning indicator lamp which remains illuminated until all doors are closed or the ignition switch is no longer in the RUN position.

----------------------------------------------------------------------------------------------
Key-in-Ignition Warning The generic electronic module (GEM) sounds when the LH front door is opened with the key in the ignition switch and continues to sound until the key is removed or the door is closed.

• When the key is in the ignition switch, the ignition key warning switch terminal and wire (11A128) is closed and ground is supplied through Circuit 158 (BK/PK) to the generic electronic module (GEM).
• When the LH front door is open, the LH front door open warning lamp switch (10B997) closes and ground is supplied through Circuit 57 (BK) to the generic electronic module (GEM).

-------------------------------------------------------------------------------------
Safety Belt Warning When the ignition switch is turned to RUN or START from the OFF or ACC position and remains in RUN or START, the chime will sound for six seconds or until the safety belt is buckled. The safety belt warning indicator lamp (10C859) will turn on for 60 seconds, or until the LH front safety belt is fastened. Both the chime and lamp activate at the same time. If the safety belt is buckled when the ignition key is turned to RUN or START from OFF or ACC, the lamp will prove out for two seconds, but chime will not be activated. Any time the key is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed, or the safety belt is buckled.
