Air bag code 28 - 2000 Ford Ranger SuperCab

If the air bag light is on there is a code stored in the SRS restraint module - air bags ! Wiring problem , impact sensor ! First place to start is have the vehicle check for codes . Not with OBD2 code reader., factory or professional grade scan tool . If you have not worked on air bag systems I recommend you take it to a ASE certified repair shop or the dealer . People have been killed by accidental air bag deployment , by not knowing what's up . Takes special tools !

. Were did you check for codes ? an what are you checking with ? you need a factory scan tool to check for those type codes ? or the light flashes codes
Lamp Fault Code (LFC)
When the RCM detects a fault, it will cause the air bag indicator to flash a coded sequence called a LFC. The code is one digit. The digit is indicated by a number of flashes with a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indicator will remain lit as long as the key remains in the RUN position. If there are multiple LFCs, each LFC will flash in order of priority.
Each LFC has one or more associated DTC.

1. Press TRIGGER. The RCM will run the On-Demand Self-Test and display On-Demand DTCs (reflecting hard system concerns) on the screen.

a DTC: Diagnostic trouble code
b LFC: Lamp fault code, flashed on air bag indicator.

I think that a scanner can clear the DTC (diagnostic trouble code).
It seems to me that if a problem is detected that the light will stay on to alert the driver until cleared.
General Information The supplemental restraint system was designed to provide increased protection in case of an accident for those in the front seat of the car, when used along with the safety belt system. The system MUST be disarmed before any work is performed on or around the supplemental air bag system. The system is an electronically controlled, mechanically operated system. The system contains two basic subsystems: the driver's side air bag module assembly and the passenger side air bag assembly, and the electrical system that connects them. The system consists of:

• The crash sensors
• The safing sensor
• The air bag module(s)
• The diagnostic monitor
• The back-up power supply
• The instrument cluster indicator
• The sliding contacts (clock spring assembly)

The system is operates as follows: The system remains out of sight until activated in an accident that is determined to be the equivalent of hitting a parked car of the same size and weight at 28 mph (40 km/h) with the vehicle receiving severe front end damage. This determination is made by crash and safing sensors mounted on the vehicle which when a sufficient impact occurs, close their contacts completing the electrical circuit and inflating the air bags. When not activated the system is monitored by the air bag diagnostic monitor and system readiness is indicated by the lamp located on the instrument cluster. Any fault detected by the diagnostic monitor will illuminate the lamp and store a Diagnostic Trouble Code (DTC). Fig. 1: Air bag system component locations — 1990–91 vehicles
Fig. 2: Air bag system component locations — 1992–00 vehicles

Seems to be a very common problem with Ford. The wiring harness beneath the drivers seat contains the sensors for the airbag system. Go under the drivers seat and secure all the wires and clips. This makes most error lights for the airbags go away. Hope this helps and good luck!

If a concern is detected, the air bag control module will communicate by flashing the warning indicator. A diagnostic trouble code (DTC) is logged by the air bag control module in a nonvolatile memory. For additional information, refer to Diagnosis and Testing in this section.

Yes, it's called a lamp fault code.

9 is not familiar to me. Call dealer service department and ask them what code means.

Here are codes for a 94 Aerostar. I don't have 91 Sable. Sorry.

I strongly suspect you have a bad connection or corroded connection at one of your connectors.

Here's the LFC (lamp Fault Codes) for 36:

B1993 36 22 Driver Side Air Bag Circuit Shorted to Ground GO to Pinpoint Test V . B1992 36 24 Driver Side Air Bag Circuit Shorted to Battery or Ignition GO to Pinpoint Test W . B1994 36 26 Driver Side Air Bag Circuit Resistance High GO to Pinpoint Test X . B1995 36 28 Driver Side Air Bag Circuit Resistance Low GO to Pinpoint Test Y .

Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.

• Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
• If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
• If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.

Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.

• If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
• If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.

Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.

1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.

1. Cycle the ignition switch to OFF and then to RUN.

1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).

1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
