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

B2292 d 34 Restraint System - Seat Belt Pretensioner Fault (Passenger Pretensioner Circuit Fault) Go To Pinpoint Test R .
PINPOINT TEST R: LFC 33 AND 34/DTC B2292 - RESTRAINT SYSTEM - SEAT BELT PRETENSIONER FAULT NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the pinpoint test.
NOTE: The retractor pretensioner connector keying is different between vehicles. The retractor pretensioner connector shown in the following pinpoint test is equipped on the Five Hundred, the connector equipped on the Freestyle and Montego is similar.
Test Step Result / Action to Take R1 CHECK FOR CONTINUOUS OR ON-DEMAND DTCs
    WARNING: Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards. WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow these instructions may result in the inadvertent deployment of the safety canopy and risk of personal injury. WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. WARNING: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury. WARNING: Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment. NOTE: If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered. NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  • Enter the following diagnostic mode on the diagnostic tool: On-Demand Self Test.
  • Enter the following diagnostic mode on the diagnostic tool: Flag DTC B2292/ Record All Flagged Faults.
  • Enter the following diagnostic mode on the diagnostic tool: Retrieve/Flag /Record Continuous DTCs.
  • Was DTC B2292 retrieved during the on-demand self test?
Yes
This is a hard fault. The fault condition is still present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self test. GO to R2 .

No
This is an intermittent fault. The fault condition is not present at this time. Your best bet , take it to a qualified repair shop .

On my 05 Ford mustang v6, my fan only comes on when i turn my AC on and makes a funny noise when I turn the AC on, diagnostic test gave me a code, u1900, what does this mean and how do I fix it?


Where did you pull this code from ? What type scan tool did you use ,or was it a code reader ? Do you know about data communication networks on modern cars ? A U codes indicate a communication problem on the data network .
U1900 CAN Communication Bus Fault-Receive Error Audio Control Module REFER to Section 418-00 . U1900 CAN Communication Bus Fault-Receive Error ABS Module REFER to Section 418-00 . U1900 CAN Communication Bus Fault-Receive Error Instrument Cluster REFER to Section 418-00 . U1900 CAN Communication Bus Fault-Receive Error SJB REFER to Section 418-00 . The thing that would make this easier to diagnose would be to have a factory scan tool or a professional grade . Need to know what modules can communicate with scan tool .Honestly ,Don't think you can fix this . Dealer or ASE certified repair shop .Do you know what C.A.N. - controller area network is ? The vehicle has 3 module communications networks:
  • high speed controller area network (CAN)
  • medium speed CAN
  • international standards organization (ISO) 9141 communications network
The diagnostic tool connects to the communications networks through the data link connector (DLC). The DLC allows a diagnostic tool access to diagnose and test the vehicle systems of any module on the communications networks.
All 3 communications networks are connected to the DLC. This makes diagnosis and testing of these systems easier by allowing one diagnostic tool to be able to diagnose and control any module on the 3 communications networks from one common connector. The DLC can be found under the instrument panel between the steering column and the driver door. Which module doesn't communicate with scan tool ?

99 sienna, fuel pump changed out & can hear pump humming wen key turned on but it won't start..it almost starts but nothing..dnt have diagnostic tester


Check for proper fuel pressure, 44--50 psi. If your going to work on your own vehicles, you need a few basic test instruments, other wise your just spinning your wheels, hoping you get lucky and find the problem. You need a fuel pressure gage with the proper fittings to hook it up, if no Schrader valve. Also, you need an obd2 code reader, a basic tool. Some of them don't cost that much.

Check fuel pressure--visually check for spark at all the spark plugs--check for fuel injector pulse. Check valve timing.

2013 Sienna starts and dies. No fault codes. If I give it more then 50% throttle and play with it It will stay running. Anything less and it dies. Starts up normal but dies almost immediately. No Antitheft...


no fault code where? on the Pro OBD2 scan tool screen>?
should be in warranty, why not let them fix it?
tow it there.?

bravo that, first post ever with fast right foot test, you are on the ball.
ok, that means this.
1: it's not losing 12vdc power to run the EFI. all lamps are not dim.
2: the fast foot test, implies to me, spark is ok, (unless one cylinder shut down, a bad COP?. but the scanner will see that for sure and did not. Gross misfire, is never unreported by the scan tool. (PCM)
gross enough to stall the engine.
so fueling issues.
id check for flooding or starving for fuel. and bad fuel.

Ok so my guess, is its losing fuel pressure or you got bad fuel.

2006 Toyota Sienna XLE: Traction control is triggering for no apparent reason


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.


The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.
