SOURCE: 1993 Mustang Convertible Airbag Code 24. What's wrong?

Safing Sensor Diagnostic Circuit Open Or Low Resistance In A Primary Crash Sensor.

Each primary crash sensor has an internal resistor. The diagnostic monitor uses the resistor in the primary crash sensors in combination with the two resistors inside the diagnostic monitor to create a tightly controlled diagnostic voltage at Pin 11 (Circuit 614, GY/O). The primary crash sensors are tied together inside the diagnostic monitor at Pins 17 (Circuit 617, PK/O), 18 (Circuit 619, PK/W) and 19 (Circuit 621, W/Y). Therefore, the resistors in the sensors are connected in parallel. The parallel combination of all three sensor resistors should be equal to 393 ohms. The resistance of each sensor should be 1180 (± 20 ohms) ohms. The resistors inside the diagnostic monitor are connected to Pins 11 (Circuit 614, GY/O) and 12 (Circuit 623, P/W) and are equal in value. Note that Circuits 614 and 623 are tied together inside the safing sensor. Therefore, the two resistors inside the diagnostic monitor are connected in parallel and will function the same as one resistor of half the original value. Current flows from Pins 1 and 6 through the resistors, out to Circuits 614 (GY/O) and 623 (P/W) on Pins 11 and 12, through the LH B-pillar safing sensor and out to the driver side air bag. Current flows through the driver side air bag and into Pin 10 (Circuit 615, GY/W). Current then flows from Pin 10 through the diode inside the diagnostic monitor and out to the primary crash sensors through Pins 17, 18 and 19. The current flows through each primary crash sensor resistor and ends at the case ground of each sensor. Pin 11 is the midpoint of the resistor network and voltage at Pin 11 will change with vehicle charging system voltage. The expected voltage at Pin 11 is shown in the table below. The diagnostic monitor measures the vehicle charging system voltage at Pin 13 (battery input). By measuring the voltage at Pin 13, the diagnostic monitor can accurately predict what the voltage at Pin 11 should be in a normal functioning system. If the connection between Circuits 614 (GY/O) and 623 (P/W) inside the safing sensor is broken, then the resistor on Pin 12 is no longer in the diagnostic circuit. Both resistors are needed to pull up the diagnostic voltage to the correct value. In this situation, the resistor on Pin 11 is the only resistor inside the diagnostic monitor pulling up the voltage. Therefore, the voltage on Pin 11 will be half of the normal expected voltage and the voltage on Pin 12 will be about equal to the vehicle charging system voltage. The diagnostic monitor does not measure the voltage on Pin 12, so the monitor bases its decision strictly on the voltage at Pin 11. If the voltage at Pin 11 is lower than it should be, the monitor will flash Diagnostic Trouble Code 24. Another situation that can cause low voltage at Pin 11 is a drop in primary crash sensor resistance (resistance is too low). If this occurs, the voltage at Pin 11 will be pulled down to a lower than normal value because the parallel combination resistance of the primary crash sensors will be less than 393 ohms. In this situation, the voltage at Pins 11 and 12 will be identical, but the monitor does not measure the voltage at Pin 12. Therefore, a primary crash sensor with low resistance may cause low voltage at Pin 11 and the monitor will flash Diagnostic Trouble Code 24 on the air bag indicator.
Here is a wiring schematic of this.

SOURCE: on my 1993 ford mustang Lx 4 cyl,if I drive car

Had similar problem with previously owned mustangs (80 & 87 with 4 cylinder) on two different occasions. One time the coil was opening up after I drove it and it heated up. It would not start again until it cooled down. The other time it was the TFI module on the distributor. Only way I can suggest to test coil is wait for engine to shut off; then pull the coil wire off the distributor and have someone turn the key to see if you have spark while holding near the side of the engine compartment. If you try this be careful as the coil has a kick to it if it is good. Not sure how to test the TFI module unless you check for engine codes. Hope this helps.

SOURCE: 1992 ford mustang lx 2.3L will not start

The crankshaft sensor went bad. I Was'nt getting any fire from the coil pack. Tried switching coils and still nothing, tried switching ignition modual, nothing. I checked to make sure it was in time and it was. Nothing left to check so I changed the crank sensor and it firerd right up! Thanks.

SOURCE: 1993 mustang 5.0 lx conv rear power window does

More than likely it is going to be the switch on the drivers side door. The "master switch" if you will for all of the windows. It is possible that the ground connection came loose from the motor, or there is simply a short in the wiring. Nine times out of ten it is just a problem with the switch. Personally I have a 1995 Mustang GT and my rear drivers side window would not go down. I replaced the switch "it will have controls for all four windows" and now it works fine.
