If a SRS fault exists, the RCM sends a message to instrument cluster module to flash a coded sequence which is called a lamp flash code (LFC) on the air bag warning indicator. Each LFC is flashed 3 times after which the air bag indictor will remain lit for the remainder of the key-on cycle. In addition to the self-test at start up, the RCM continuously monitors all of its external and internal circuitry for faults.
While the LFCs are an indication of a general concern in the supplemental restraint system (SRS), the DTCs are more specific. The DTCs can be retrieved from the RCM with a scan tool via the DLC.

What is the fault when the air bag dash light flashes code 49


It's a common fault on many Fords, usually due to a poor connection in the YELLOW PLASTIC CONNECTOR underneath the passenger seat. Just push it together properly and it should clear the fault. If not, go under the drivers seat and secure all the wires and clips there as well.

Air bag light on


the flashing is a code, you need to get a pen and a piece of paper and decode this. It is a two digit number the first set of flashes is the first number so lets say it flashes 3 times and then pauses for 3 to 5 seconds your first number would be 3 and then after the pause it blinks 4 times that would be your second number... so your code would be 34. anyways here is a list of the code meanings so after you count the two set of flashes and get your code compare it here

12=Low Battery Voltage
13=Air Bag Circuit Shorted to Ground
14=Primary Crash Sensor Circuit Shorted to Ground
21=Safing Sensor Not Mounted to Vehicle Properly
22=Safing Sensor Output Shorted to Battery Voltage
23=Safing Sensor Circuit Input Feed/Return Circuit Open
24=Safing Sensor Output Feed/Return Circuit Open
32=Driver Side Air Bag Circuit High Resistance or Open
33=Passenger Side Air Bag Circuit High Resistance or Open
34=Driver Side Air Bag Circuit Low Resistance or Shorted
35=Passenger Side Air Bag Circuit Low Resistance or Shorted
41=RH Primary Crash Sensor Feed/Return Circuit Open
42=LH Primary Crash Sensor Feed/Return Circuit Open
44=RH Primary Crash Sensor Not Mounted to Vehicle Properly
45=LH Primary Crash Sensor Not Mounted to Vehicle Properly
51=Air Bag Diagnostic Monitor Internal Thermal FuseFuse Blown Due to Intermittent Short to Ground
52=Backup Power SupplyVoltage Boost Fault
53=Primary Crash Sensor Circuits Resistance to Ground or Air Bag Diagnostic Fault

Airbag light flashes 1-8, stays lit


You have a bad Passenger Air Bag Deactivation Indicator. The bulb that shows when the passenger air bag is off.
Have seen alot of these go bad especially in police cars. The part number you need is 5W1Z-10A936-A.

Air bag sensor keeps flashing


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.
Lamp Fault Codes (LFC)
Item Part Number Description 1 One flash cycle: Driver air bag trouble code 2 Two flash cycle: Passenger air bag trouble code 3 Three flash cycle: Trouble code common to both driver and passenger air bag circuit 4 Four flash cycle: Safety belt pretensioner trouble code common to both driver and passenger pretensioner circuits 5 Five flash cycle: Driver side air bag trouble code 6 Six flash cycle: Passenger side air bag trouble code 7 Not used 8 Not used
