Brakes fail due to low fluid or air in the lines (usually from low fluid).
The airbags and coolant are not related to the brakes.
Have you hit some thing ?
A wiring problem could affect all three, possibly a common ground between the three ?
but you will need a "competent" tech to look at it.

Srs air bag light flashing


This code is telling you of an ECS module fault.
An ECS module fault could be caused by:

- the internal accelerometer not operating properly.
- the backup power supply not operating properly.
- an internal module circuit fault detected.
- a microcontroller RAM/ROM/EEPROM fault.

Before doing any of the above, disconnect the vehicles battery and Remove the main connection off of the ECS and clean with electrical connection cleaner, then reinstall, then check the connectors and wires under the seats - these fail all the time.
After checking and cleaning reconnect battery.

My 2002 dodge Durango the abs light , the brake light, and the air bag lights stay on making my air conditioner and speedometer not work.


None of those systems interact with each other, besides a communication link. The ABS and Air bag will not cause the speedo or A/C to quit working. You'll have to take it to a garage to see what has failed on each system.

Air bag light flashes code 51.


If your airbag code is blinking, and you get 51, it means that your internal thermal fuse in your airbag computer is blown which is caused by an intermittant short to ground on one of the wires in the circuit. When the short to the ground is removed, code 51 flashes with the use of the airbag warning lamp, 5 flashes, pause, 1 flash, longer pause. According to the Ford, this is a nonrepairable fix, you must buy a new air bag module which is a blue box located in the vicinity of the the steering column.

Obviously it's temperature gauge light. Check for coolant level first. Then check for coolant leak. If coolant is leaking out of your car, the lower coolant levels in your engine will cause it to overheat. If you have your heater on and it starts blowing hot air instead of cool, your engine is low on coolant. This will cause to flash a warning light on your car's dashboard.

Airbag light flashing 5-2


this indicates that the air bag solenoid circuit has failed it's test. which means you need to have the air bag circuitry checked. since this is a safety feature, and you could cause the air bag to inflate by accident. I will only recommend taking it to a qualified mechanic.

Flashing airbag light on 97 maxima. Car was in an accident, airbags deployed, replaced bags and controller why won't the light stay off


To manually check air bag codes, turn the key On and push the driver's door switch (at the bottom of the B-pillar) 5 times or more within 7 seconds of turning the key ON. Then watch the air bag light flashing codes. The air bag light will come ON for 3 seconds and then give fast flashes if there is a code. Count the fast flashes as the code. So the air bag light on for 3 seconds and then 8 flashes is a code 8 for the passenger air bag circuit. after counting code clear codes and see if they come back

How do I fix a code 44 problem? Air bag light


The air bag code 44 indicates that the air bag computer is not receiving a signal from the right front air bag sensor. This could be caused from defective wiring (loose wire or grounded through chafing) or the sensor being defective.

Air bag light keeps flashing!!!I have a 1999 mazda 626 2.0


The air bag light flashing is indicating the SRS module has detected a failure in the air bag system. It could be anything from a sensor to bag module or wire connection.
I would take your vehicle to your local Auto Zone or Advance Auto and ask them to scan your car for trouble codes, they will do it for you at no charge, write the codes down and respond back and we can begin to diagnose the problem.
Good luck.

Air bag light comes on and stays on. Never any accidents.


Had the same problem, found the wire disconnected under the driver seat (there is a yellow plug and with one red wire, which is fine, and one green wire, which is broken. Fixed the wire, light went off.

Airbag flashes 10 times misses a flash then repeats


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.
