This is Airbag code 52

A. Here is the information you will need to check the code 52. You need to be very, very careful when working with the SRS system.
Always wear safety glasses when servicing an airbag vehicle and when handling an airbag module.
Because of the critical operating requirements of the system, do not attempt to repair sensor assemblies, the slip ring/clockspring assembly, the monitor assembly or the airbag module. Corrections are made by replacement only.
Never probe the connectors on the airbag module. Doing so may result in airbag deployment which could result in personal injury.
All component replacements and wiring repairs must be made with the airbag system disarmed. See Airbag System Disarming and Arming.
The instruction DISCONNECT always refers to a connector. Never detach a part from vehicle when instructed to Disconnect. If a vehicle equipped with an airbag system is involved in a crash where the fenders or grille area have been damaged, the sensors in the area of damage must be replaced whether or not the airbag deployed.
When carrying a live airbag module, ensure bag and trim cover are pointed away from body. In the unlikely event of an accidental deployment, the bag will then deploy with minimal chance of injury. In addition, when placing a live airbag module on a bench or other surface, always place bag and trim cover face up, away from the surface. This will reduce the motion of the module if it is accidentally deployed.
After deployment, the airbag surface may contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Always wear gloves and safety glasses when handling a deployed airbag module.
Fault Code 52 - Backup Power Supply Voltage Boost Fault.
Normal Operation:
A backup power supply is contained within the diagnostic monitor that consists of four capacitors and a voltage boost circuit. The voltage boost circuit charges the capacitors to 16-19 volts when the ignition switch is turned to ON. The backup power supply is connected through a diode to diagnostic monitor pin 15 (Circuit 611, W/O). The resistance of Circuit 611 to ground is infinite since it is an open circuit. This open circuit allows the capacitor to maintain its higher voltage because there is no discharge path for the capacitor. The diagnostic monitor measures the voltage on the backup power supply capacitors. If the voltage on the capacitors does not reach and maintain a minimum of 16 volts after approximately 45 seconds , the diagnostic monitor will flash code 52 to indicate low voltage in the backup power supply voltage boost circuit.

I just bought a 2003 Ford F150, and a warning chime goes off right after starting. Chimes 5 times, pause, and repeat 4 more times. There are no lights or codes displayed on the dash. It drives fine, but...

The warning chime of 5x5 is a sign that the SRS ( airbag ) light is burnt out, and there is an error with the SRS system.

Verify SRS ( airbag ) lamp operation, turn the key from off to run ( do not start ) the airbag lamp should illuminate. If not, it is burnt out. Need to pull the cluster and replace.
( thread at on cluster removal in the how to forum - titled about changing cluster illumination color or installing a cluster overlay ).

Once you replace the SRS bulb, you will get a LFC ( light Flash Code ) of a 2 digit number.
Example :
flash flash flash flash { short pause } flash flash { longer pause } flash repeats the same for 5 times, the solid on.
This is an example of a LFC 4-2. Once you have the LFC start a new problem with the LFC and we can get that fixed after you get the bulb replaced.

I'm getting an audible alarm from my instrument cluster as the air bag light doesn't light up with the rest of my instrument lights when i turned the key to on the alarm is 5 beeps appox. 5 times is there...

Replace the airbag lamp in the cluster, and get the LFC ( Light Flash Code ) to figure out what the problem is with the SRS.
The 5x5 beeping is an indication that there is a SRS problem waiting and the airbag light cannot give the LFC. Page 105 in the owners manual.

Once you replace the airbag light, you will get a LFC that is a 2 digit number presented by the flashes.
Example is a LFC of 42, the airbag light would flash 4 times, pause flash 2 times pause and repeat.

Once you have the LFC, either start a new problem, or add a comment to this problem with the number for further diagnoses.

What is the 5 chime, cycling 5 times, then off? comes on after I start the car. Thanks, Jim

Is your airbag light on or not working? does your seatbelt light work? do you wear your seatbelt? This type of chime usually indicates a problem in the SRS system. (safety restraint system) Assuming 5 chime pause 5 chime pause and continues for 5 cycles and then stops.

Ford 2001 F150 pickup truck beeps approx 5-6 times every 5 minutes. Think i has to do with the airbag.

Yes you are correct, it is an airbag problem./

The Airbag indicator lamp is burnt out, and a flash code is waiting.
Radio shack ( or similar ) should still have the replacement bulb for it.

Once you put it back in, the airbag lamp will flash a code that is a number, t ( ie flash 3 times ) then another number ( ie flash 5 times ). You will need that code for the next step in the diagnoses. Don't be alarmed if you get 10 sets of 3 flashes, that is actually a LFC ( Light Flash Code ) 33

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.
