Code 52 relates to low voltage detected in a capacitor inside the airbag module. 45 seconds after key on, this capacitor should have a voltage of around 23 volts.

This capacitor stores energy to deploy the airbag in the case of a collision.

Because your airbag light is on, your system is deactivated (cannot deploy)

In your case, the airbag computer detects less than 23 volts at that capacitor 45 seconds after key on, and disables the system.

There is a diagnostic procedure involved in fixing this problem, but usually means a bad airbag module (computer)

This should only be checked by a qualified technician, as airbag service can be dangerous and there are strict procedures to follow so the bags don't inflate suddenly and cause injury.

Hi, ON your 2002 ford taurus, The Flashing code 33 ( B 2292 )

But if you had an accident on you taurus. You need to replace the Seat belt Pretentioner ( seat belt bucklet)

OK. I hope this information work for you.

My air bag light on my 2000 Ford Econoline van flashes a 19 code. Does anyone know what that means?

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!

I have a 2005 Ford Taurus SEL with code 42 flashes and then stays on

It is a air bag code. If the light is on the air bags will not work in an accident, you need to have it repaired.

Air bag Indicator flashed and than stays on

If the only code 52 is flashing then system is ok and just needs to be cleared.Look behind the glove box and find the gray 2 wire connector.It will be on the left side behind the glove box and follow the proceedure below. Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVM. 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 Service Connector located underneath the glove compartment 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.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (T/R) to Circuit 57 (BK). Diagnostic trouble code is now cleared from NVM. Next highest priority diagnostic trouble code stored in NVM (if one exists) will begin flashing

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.

1999 ford explorer ( air bag light)

Since my last post, I found a bright yellow connector under the drivers seat. I took the connector off of the end, bent it a little, and put it back on. My air bag light has stayed off. I am going to put some electrical grease on it and see what happens.
