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 .

you need haynes repair manual for 1993 suburban it has photos and information you need to help you replace ignition switch.i am mechanic i use haynes,chiltons and gm manuals.if you are a home mechanic do it your self you need haynes repair manual it has step by step instructions to remove the steering wheel and remove lower steering column reason i say need haynes repair because your steering wheel has a air bag in it you need to see how to remove air bag in steering wheel you need to read through the entire ignition switch removal procedure if you are going to replace ignition switch with keylock cylinder you will also need steering wheel puller. you need a tool compress lock plate to remove lock plate retaining ring from steering shaft in order to get to the ignition switch in the steering column below turn signal switch.

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.

The mechanic should check the ignition switch of the car . prepare the equipment to be used then check the ignition switch, check the wires that are connected to the ignition switch that connect to the battery. you also have to check the fuse if the ignition switch is worn out or destroyed then repair or replace.The wires if there are worn out or destroyed wires and fuses then replace , if loose wire connection then reconnect them.But to figure it out the problem is only in the ignition switch and its wires or wire connections.You just have to repair and reconnect the wires and repair the ignition switch.
