SOURCE: Air Bag Code

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.

What is a b2293 code on 2003 mercury mountaineer


B2293

Pinpoint Test H: LFC 19 and 21/DTC B2293 - Restraint System Airbag Status
Normal Operation
The restraints control module (RCM) checks all of the front air bag circuits for faults. If the RCM detects one of the following faults on any of the front air bag circuits, it will store diagnostic trouble code (DTC) B2293 in memory and, depending on the fault, flash either lamp fault code (LFC) 19 or 21 (or higher priority code if one exists) on the air bag indicator.
Fault Conditions
The RCM monitors for the following fault conditions:
  • low resistance.
  • circuit open.
  • circuit short to voltage.
  • circuit short to ground.
Possible Causes
A driver air bag status fault can be caused by:
  • damaged wiring, terminals, or connectors.
  • a faulty clockspring.
  • a faulty driver air bag module.
  • RCM is faulted.
A passenger air bag status fault can be caused by:
  • damaged wiring, terminals, or connectors.
  • a faulty passenger air bag module.
  • RCM is faulted.

Airbag light on. flashing 5 times 2 times then stays on


I think you have a false code stored due to your work. clear the code and you should be ok.
If the air bag indicator does not illuminate or the indicator stays on or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
Diagnostic trouble codes (DTCs) may not be displayed for approximately 30 seconds after the ignition switch is placed in the RUN position. This is the amount of time the air bag diagnostic monitor requires to perform all tests and verify system faults.
Each DTC (a series of flashes and pauses of the air bag indicator):
  • Represents a two-digit number.
  • Is always displayed at least twice.
If the diagnostic monitor detects a fault in the air bag system, a diagnostic trouble code (DTC) will be written to the diagnostic monitor's Non-Volatile RAM (NVRAM). This DTC will then cause the lamp to flash a lamp fault code (LFC) on the air bag warning lamp and can be retrieved with the New Generation STAR (NGS) tester. After servicing the DTC may then be cleared from the NVRAM.
If a system fault is present and the air bag indicator is malfunctioning, an audible tone will be heard. The tone is a series of five sets of five beeps. If the tone is heard, the air bag system needs attention.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor will attempt to remove deployment power by turning on a solid state switch to blow the 10A battery fuse.

If the 10A battery fuse has successfully been blown by the air bag diagnostic monitor, the air bag diagnostic monitor will not attempt to blow it again until the proper fault has been repaired and cleared (refer to Diagnostic Instructions). The air bag diagnostic monitor will store both the unwanted deployment diagnostic trouble code and the loss of deployment power diagnostic trouble code. The loss of deployment power diagnostic trouble code is the highest priority.
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor has an internal fuse that that will blow (open) automatically. This removes all power to the air bag deployment circuit.
DTCs are prioritized numerically. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the event the battery (10655) or battery cables are damaged in a collision before safing and air bag sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.
---------------------------------------------------------------
Once a DTC is logged into the air bag diagnostic monitor memory, it will stay in memory until 80 key cycles have been recorded or until the NGS is used to erase the DTCs. Once 256 key cycles have been recorded since the concern was last detected, the DTC will automatically be removed from memory.
--------------------------------------------------------------
Active Command Modes
This command allows the technician to verify operation of the air bag system, indicator and tone. When the air bag output command is executed, the indicator and the tone are simultaneously activated for approximately four seconds. Both devices are automatically deactivated.

Diagnostic Test Modes Without Scan Tool
Two mode options are available under the diagnostic test modes:
  • user mode.
  • diagnosis mode.
The ignition switch is used to alternate from one mode to another.
Diagnosis Mode
The diagnosis mode will display any fault present in the system. The SRS will not enter diagnosis mode if no malfunction is detected.
User Mode to Diagnosis Mode
NOTE: The SRS will not enter diagnosis mode if no fault is detected in user mode.
  1. Ignition switch to ON.
  1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.
  1. Wait more than three seconds.
  1. Repeat steps 1 through 3 three times.
  1. Ignition switch to ON.
Diagnosis Mode to User Mode — After Repair
  1. Ignition switch to OFF for at least one second.
  1. Ignition switch to ON.
Diagnosis Mode to User Mode — During Diagnosis
NOTE: If switch from Diagnosis Mode to User Mode is required while diagnosing a fault, carry out the following procedure.
  1. Ignition switch to ON.
  1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.
  1. Wait more than three seconds.
  1. Repeat steps 1 through 3 three times.
  1. Ignition switch to ON.
Clearing Lamp Fault Codes
NOTE: Lamp fault codes must be cleared from memory before proving out the system.
NOTE: When a new RCM is installed, the air bag warning indicator will operate in user mode. Switching to diagnosis mode is not required.
To clear lamp fault codes after a repair, carry out the procedure to switch from diagnosis mode to user mode. Once in the user mode, the lamp fault codes will be cleared from memory.
Lamp Fault Codes
If the air bag diagnostic monitor detects a current fault, the fault code will be displayed with a flashing sequence of the air bag indicator. The fault code consists of:
  • A start signal to indicate the beginning of a fault code.
  • A number of flashes indicating the particular code that has been set.
The start signal:
  • begins with two seconds off.
  • two seconds on.
  • off.
  • one second on.
  • two seconds off.
Following the start signal, if any current fault is detected, the fault code will be displayed. The fault code:
  • is a series of half second flashes of the air bag indicator.
  • is followed by the start signal.
The start signal and the code for any current fault will repeat until the ignition is switched off or the air bag diagnostic monitor is switched to the user mode.
Inspection and Verification
  1. Verify the customer concern by checking the air bag indicator in the instrument cluster. Refer to Prove Out in this section.
  1. Visually inspect for obvious signs of mechanical and electrical damage using the following chart.


Visual Inspection Chart Mechanical Electrical
  • Damaged air bag diagnostic monitor bracket
  • Open fuse
  • Damaged wiring harness
  • Loose or corroded connectors
  • Circuitry open or shorted
  • Damaged shorting bars

  1. If the concern is not visually evident, enter the system Diagnosis Mode.
  1. If no DTCs are displayed in the Diagnosis Mode, proceed to the Symptom Chart in this section.
  1. If DTCs are retrieved, proceed to the Air Bag Diagnostic Monitor Fault Code Table in this section.

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.
