Dtc p0743 check light o/d blinking

What code ? Plugging in a scan tool to check codes is how it's done , not by the light blinking an then staying on . Your best bet , take it to a qualified repair shop.

AIR BAG Indicator
The AIR BAG indicator, located in the IPC is used to notify the driver of SIR system malfunctions and to verify that the SDM is communicating with the IPC. When the ignition is turned ON, the SDM and the IPC are supplied with ignition 1 voltage. The IPC responds by flashing the AIR BAG indicator seven times. While the IPC is flashing the AIR BAG indicator, the SDM conducts tests on all SIR system components and circuits. If no malfunctions are detected, the SDM will command the IPC to turn the AIR BAG indicator OFF via Class 2 serial data. The SDM provides continuous monitoring of the inflator module circuits by conducting a sequence of checks. If a malfunction is detected, the SDM will store a DTC and command the IPC to turn the AIR BAG indicator ON via Class 2 serial data. The presence of a SIR system malfunction could result in non-deployment of the inflator modules in the event of a collision, or deployment of the inflator modules without the event of a collision. The AIR BAG indicator will remain ON until the malfunction has been repaired.


Code's on a factory or professional scan tool look like this
DTC B0012, B0013, B0014, B0016, B0017, or B0018
DTC B0022, B0024, B0026, B0042, B0043, or B0044
DTC B0028, B0029, or B0030
DTC B0040, B0041, or B0045
DTC B0051
DTC B0053
DTC B0057, B0058, or B0059
DTC B0064, B0065, or B0066
DTC B0077, B0078, B0079, B0080, B0081, or B0082
DTC B0100, B0101, B0102, B0103, B0104, or B0105
DTC B1001


Doesn't do the flashing light code thing .

Here is some info on your problem....


P0743 Torque Converter Clutch TCC Solenoid Circuit Electrical

code p 0743 refers to torque converter clutch (TCC) solenoid---electrical====causes --wiring--TCC solenoid---ECM/TCM

P0743 Torque Converter Clutch Circuit Electrical
P0760 Shift Solenoid C Malfunction

For bower fan check:
- Speed controller assembly of blower fan.
- Wiring harness and fuse
- Blower fan.
To solve the air bag light problem retrieve the SRS error codes with the help of diagnostic computer and follow the description.
You can also check the error codes manually as described below.


Procedure:
Read the blinking patterns of the DTCs. As examples, the blinking patterns for the normal system code and DTCs 11 and 31 are shown in the following diagram. The first blinking pattern indicates the first digit DTC. The second blinking pattern occurs after a 1.5-second pause. If there are two or more DTCs, there is a 2.5- second pause between each DTC. After all DTCs are shown, there is a 4.0-second pause, and they are all repeated.
HINT:
• If 2 or more malfunctions are found, the indication begins with the lowest numbered DTC.

P0700 is a request for the check engine light to come on. P0743: Torque converter clutch solenoid circuit problem. Circuit open, circuit shorted to ground, short to another circuit, faulty solenoid, or transmission control computer faulty. Most likely problem is TCC solenoid is faulty. Test solenoid out of vehicle if possible. Replace and retest.

O/D light blinks, but with that the check engine light is ON.--- This will make your troubleshooting easier.When the check engine light comes on, and remains on, this indicates that there is error stored in your cars computer.---- Once the computer is scanned, you will get error codes, as per that error code it will point towards faulty part, which is causing the O/D light to blink.-------- Most probably the O/D light blinks, If a problem exists in No. 1 or No. 2 solenoids or speed sensors .
--------------- For car after 1995 it requires OBD2 tool and for car before 1995 it requires OBD1 tool.------- --------- You car will require OBD1 tool.There are very few auto parts store and repair centers who have OBD1 tool.In your case you required OBD1 tool.------ You can just contact local auto-parts store and they will guide you to the nearest store who has OBD1 tool.There you can get your car scanned.If there is error set in your cars computer, then you will receive the error code.As per error code it will point towards the faulty part causing this problem in your car.------------- -------------- The codes which you get is scanning will be mostly any of this following codes:--- DTC P0500 - Vehicle Speed Sensor Malfunction
. DTC P0750 - Shift Solenoid "A" Malfunction
. DTC P0753 - Shift Solenoid "A" Electrical Malfunction
. DTC P0755 - Shift Solenoid "B" Malfunction
. DTC P0758 - Shift Solenoid "B" Electrical Malfunction
. DTC P0770 - Shift Solenoid "E" (SL) Malfunction
. DTC P0773 - Shift Solenoid "E" (SL) Electrical Malfunction
. DTC P1520 - Stop Light Switch Signal Malfunction
. DTC P1705 - Direct Clutch Speed Sensor Circuit Malfunction
. DTC P1765 - Shift Solenoid Valve SLN Circuit Malfunction
. DTC P1780 - Park/Neutral Position Switch Malfunction --------------- Now it all depends on what code you get, as per that you can replace the following part.------- This will help.Thanks.Helpmech.

I don't have access to my manuals right now, but do this - google "Ford DTC code P0102" and see what comes up. Then do other codes same way. You will be sure to gert ideas, especially if it is a help site. I'll check back & see how you are doing.

Report results & progress

According to the manual

P0700 = EATX Controller DTC Present

Discription= An automatic transmission input DTC has been set in the transmission controller.

.

P1733 no listing in manual

P0743 =Torque Converter Clutch Soleniod/Trans Relay Circuits

Discription= An open or shorted condition detected in the torque converter part throttle unlock solenoid control circuit (3 speed auto RH trans. only).

hope this helps

Here are the DTC's for the TCC Solenoid:

DTC P0740 TCC Enable Solenoid Circuit Electrical
DTC P0741 TCC System Stuck Off
DTC P0742 TCC System Stuck On
DTC P0743 TCC Enable Solenoid Circuit Electrical
DTC P0744 Torque Converter Clutch Circuit Intermittent
