I'm not sure about this, but I think state, if not federal law says you have to get your airbags services by certified professionals. I suggest for your own safety that you not try that at home.

2008 ford f-350 passenger air bag flashes 1-7 code than stays on when truck is started.What does the code mean and can the code be reset without tearing air bag out of truck?


If a SRS fault exists, the RCM sends a message to instrument cluster module to flash a coded sequence which is called a lamp flash code (LFC) on the air bag warning indicator. Each LFC is flashed 3 times after which the air bag indictor will remain lit for the remainder of the key-on cycle. In addition to the self-test at start up, the RCM continuously monitors all of its external and internal circuitry for faults.
While the LFCs are an indication of a general concern in the supplemental restraint system (SRS), the DTCs are more specific. The DTCs can be retrieved from the RCM with a scan tool via the DLC.

On my 05 ford five hunmdred the air bag light flashes 3 times then pauses and then flashes four times does this twice I think and stays on


Which light ? on the instrument cluster or the passenger side .
If a lamp fault code (LFC) is reported by the customer but is not present when the vehicle comes in for service, follow the Diagnostic Instructions procedure in this section to identify the intermittent DTC.

Lamp Fault Codes
When the restraints control module (RCM) detects a system fault, it will cause the air bag indicator to flash a coded sequence; a lamp fault code (LFC). The code is 2 digits. The first digit is flashed with a 0.5-second interval between pulses. There is a 2-second pause before the second digit is flashed which also has a 0.5-second interval between pulses. There is a 5-second pause between each display of an LFC.
Each LFC is flashed 3 times after which the air bag indictor will remain lit for the remainder of the key-on cycle. If there are multiple LFCs, each LFC will flash in order of priority. Lamp flash code 34

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.

Hi i have just changed steering wheel on fiesta zetec 2003 for a ST150 2005 steering wheel will the air bags and connections be compatable with each other.


. Were did you check for codes ? an what are you checking with ? you need a factory scan tool to check for those type codes ? or the light flashes codes
Lamp Fault Code (LFC)
When the RCM detects a fault, it will cause the air bag indicator to flash a coded sequence called a LFC. The code is one digit. The digit is indicated by a number of flashes with a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indicator will remain lit as long as the key remains in the RUN position. If there are multiple LFCs, each LFC will flash in order of priority.
Each LFC has one or more associated DTC.
  1. Press TRIGGER. The RCM will run the On-Demand Self-Test and display On-Demand DTCs (reflecting hard system concerns) on the screen.

06 chevy trailblazer with fault code P0506 whats best way to clean throttle body


DTC P0506

CIRCUIT DESCRIPTION

The throttle actuator control (TAC) motor is controlled by the engine control module (ECM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the ECM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the ECM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low

CONDITIONS FOR RUNNING THE DTC
- DTCs P0068, P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0117, P0118, P0120, P0122, P0123, P0171, P0172, P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208, P0220, P0121, P0222, P0223, P0230, P0300, P0336, P0442, P0446, P0449, P0452, P0453, P0455, P0462, P0463, P0496, P1516, P2101, P2135, P2176 are not set.
- The engine is operating for at least 60 seconds.
- The engine coolant temperature (ECT) is more than -60°C (-140°F).
- The intake air temperature (IAT) is more than -10°C (-14°F).
- The barometric pressure (BARO) is more than 65 kPa.
- The system voltage is between 9-18 volts.
- The vehicle speed is less than 1.6 km/h (1 mph).
- DTC P0506 runs continuously when the above conditions are met.

CONDITIONS FOR SETTING THE DTC
- The actual idle speed is approximately 100 RPM lower than the desired idle speed.
- The above condition is present for 5 seconds.

ACTION TAKEN WHEN THE DTC SETS
- The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
- The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
- Clear the MIL and the DTC with a scan tool.

2002 lincoln continental anti-theft/security lamp - sometimes at start up the lamp will flash once and then 6 times. This will continue for several minutes, even while driving the vehicle.


Pinpoint Test G: LFC 16/DTC B1925 - Passenger Air Bag Circuit Shorted to Battery or Ignition
Normal Operation
The restraints control module (RCM) checks for passenger air bag module circuit shorts to battery or ignition by monitoring the voltage of circuits 607 (LB/OG) and 616 (PK/BK) at C310b, pins 6 and 7. If the RCM detects a short to battery or ignition on either of these pins, it will store a diagnostic trouble code (DTC) B1925 in memory and flash a lamp fault code (LFC) 16 (or higher priority code if one exists) on the air bag indicator.
Possible Causes
A passenger air bag circuit short to battery or ignition can be caused by:
  • a short to battery or ignition on circuit 607 (LB/OG).
  • a short to battery or ignition on circuit 616 (PK/BK).
  • a short to battery or ignition on the passenger air bag module.
  • an RCM internal concern.

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.

Air bag sensor keeps flashing


If a concern is detected, the air bag control module will communicate by flashing the warning indicator. A diagnostic trouble code (DTC) is logged by the air bag control module in a nonvolatile memory. For additional information, refer to Diagnosis and Testing in this section.
