The airbag light is usually classified as a code 41.
U1300 is a communication error between computers If either the SDM (air bag computer) or the Pcm (engine computer) or Abs if equipped loses Voltage for a period of time (4secs) the code will set. The air bag light or the service light will be on if the code is current
Count the flashes. That is a code. Look it up in the service manual and follow its diagnostic procedure. I had code 4 on a 93 capri. I went through the diagnostic procedure and the result was everything was OK with the other circuits, it said to replace the diagnostic monitor module, which is a computer that monitors the air bags and flashes the codes. The diagnostic monitor is separate, it should not affect the operation of the air bags, it only attempts to discover faults in the air bags that would prevent their deployment, it does not actually deploy them. I am loathe to replace the diagnostic monitor (because I'm cheap). I may yet disable the light, if I can. Maybe that was your question, how do you turn off the light without actually fixing anything? The service manual says if the light is not functional, the diagnostic monitor beeps instead. So maybe I need a light that appears to be flashing, but is dark? There is much redundancy in the air bag system itself. I would hope that most of the faults the diagnostic monitor finds are not critical faults because of the built in redundancy. In other words, the diagnostic monitor might only be telling you that one level of redundancy has failed.

The diagnostic monitor is located behind glove box. It is blue color.
Air bag code " 24 " - System Disarm Failure or Internal Diagnostic Monitor Fault
Apparently, turning on the air conditioning is triggering the computer to send a DTC (diagnostic trouble code) to the check engine light. It would be in your best interest to have the OBDII connector scanned and retrieve the trouble code(s) to find what is causing the check engine light to come on.
EGR low air flow
Trouble code P0410 means:Secondary air injection system malfunction
Secondary air injection malfunction. Maybe the air pump failure or a leak?
Trouble code P0071 means: Ambient air temperature sensor range/performance problem
Trouble code P0071 means: Ambient air temperature sensor range/performance problem
Codes can only be cleared by the use of diagnostic equipment.
