Hi I am new to the forum. Can anyone tell me what it means when a 95 Mazda Miata's air bag light blinks 5 times then pauses then 2 times and then repeats that pattern continuously. Thanks

 

looked in my '96 mazda shop book (from mazda), it has: 3-batt/ fuse; 6-drivers bag; 7-pass bag. BE VERY CAREFUL, the bags deploy at about 500mph (they can kill you). discon the batt and wait for an hour for the electricity to disapate. check for loose and/or dirty contacts, loose/bad bulb, and shorts in the wires. i'd call a dealership, asking for the service dept to see if the '95 model year had other codes. let us know and BE CAREFUL!!

 

Thanks for your reply tomthedog, sounds like I will have to contact the dealer.

 

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.
Possible Causes:
Low backup power supply voltage can be caused by:
[ol][*]Resistance on Circuit 611 (W/O) to ground. Resistance to ground on Circuit 611 or Circuit 612 (P/O) will cause the backup power supply capacitors to discharge and the boost circuit will not be able to boost the voltage.[*]Boost circuit failure within the diagnostic monitor. If the voltage boost circuit in the diagnostic monitor is faulty it will not be able to raise the backup power supply voltage on the capacitor. [/ol]

 

 

Is that the same for a 94 Miata? I mistakenly asked about a 95 Miata when in fact its a 94 Miata....

Thanks for your detailed reply.

 

Yes its the same. Most likely a diagnostic module thermal fuse which is in the module itself.

 

I just figured out that the flashing air bag light (4 flashes, pause then start all over again) is my S-sensor according to the code book. The dealer called it the Air Bag Inner Sensor $468 + about $1,000 labor(its behind the firewall and heater core). My blue book is only $2,500. Does anyone know how to disconnect the air bag so light stops blinking?
