A professional scan tool,you can not afford or
or professional software,for a computer

You will only be able to afford a code reader & they
only read generic codes,not ALL info, as you suggested.

If you have no factory service manuals,you won't know
how your vehicles systems work

Then without the powertrain/emissions diagnostic manuals,
and possibly wiring diagrams,you won't have the reference
material necessary, to learn where to start any testing,once
you get codes

Can you show me a schematic of the interior fuse box on a 2006 ford Taurus that tells what everything goes to and what's hot I'm trying to fix a power window


Sorry , but this to complex , it's computer controlled by the SJB - smart junction box ( microprocessor ) If you don't have a ford factory scan tool your not going to fix anything . It's low voltage signals over the serial data communication bus , if you don't know what this is suggest you google it .
Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.

    Visual Inspection Chart Mechanical Electrical
    • Door window regulator and motor
    • Door glass top run
    • Door window glass
    • Loose, corroded connectors
    • Circuitry
    • Window control switch
    • Battery junction box (BJB) fuse(s):
      • 1 (60A)
      • 3 (60A)
      • 11 (50A)
    • Smart junction box (SJB) fuse(s):
      • 7 (20A)
      • 27 (10A)
      • 30 (10A)
    • SJB circuit breaker 10 (30A)
    • SJB rear window defrost relay 1
    • Relay center box 1 rear window defrost relay 2
    • Delayed accessory relay
    • Battery saver relay
    • Rear window defrost grid
  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
    • CAN circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 .
    • No response/not equipped for SJB, go to Section 419-10 .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self test diagnostics for the SJB.
  1. If the DTCs retrieved are related to the concern, go to the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue the diagnostics.
Your best bet is to take it to the dealer !

I have an 07 s-type twin turb0 2.7 xs, amber & red light on, friend checked with his diagnostics hand machine and said its the egr valve, Can you enlighten me on what this means and possible repair...


Your friend did they do the diagnostics associated with the code or just guess?



Hello


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.

Transmision doesn't shift


Hi Steve, Gearbox's in newer vehicles are usually computer controlled. Your best course of action will be to take the vehicle for a diagnostic scan and that will pin point the problem for you. The shift sensing is carried out inside the box in the unit named the valve body. It is so named because it contains most of the operating valves for change up and down. These are usually pressure operated and sometimes the operation will be over ridden by the electronics. The electronic management is governed by the speed of the engine and the ground speed of the vehicle. These are measured in comparison with each other and the gear change controlled electronically. If you have a problem with the speedo or rev counter in your vehicle, that could account for your problem. If the ABS light is showing constantly, that could also be a reason for the mal function. The speed sensors on modern vehicles often share duties (to cut down on cost of manufacture) and consequently a defect in something seemingly unconnected could be related to the fault you are experiencing. I hope the problem is something simple as I've described, but it can be a problem in the gear box. Lets hope for the best. Regards John

I have a 2001 mazda protege my check engine light has been on for a while but now it starting blinking. What does this mean and what should i do


Hi,

When your Check Engine light illuminates, it's an indication that your on-board diagnostic computer has detected an abnormality in one of the vehicle's critical circuits.

As the light is now blinking, this implies there is a critical fault which must be attended to URGENTLY - potentially, this could relate to a critical safety system.

I recommend you URGENTLY have the fault codes read from your vehicle's OBD computer. Autozone may do this for you at no charge, or you can take to your nearest Mazda dealership to have the codes read - this process takes only 15mins (depending on the skill of the technician), so should be at minimal cost. I also recommend you be present when these codes are read, so you can see this process for yourself.

This procedure requires in-depth knowledge of OBD diagnostics, so if you choose to take your vehicle to a basic garage, don't be surprised if they either do not know what they're doing, or charge you large sums of money to carry out a simple task.

Once the codes are read from your vehicle's computer, you will immediately know which circuits require further attention.

Do not attempt to tune the engine, nor replace any components....until after the diagnostic has been performed.


Hope this helps......

Hi,
My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave', for today.
You apparently have grounding or a bad connection problem in the electrical system.
• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew. I can only react to the information that you provide. So please judge my suggestions accordingly. • A thorough diagnostic approach involves the use of technical equipment, such as voltage meters. scanning equipment and other sophisticated devices. Diagnostic tools can be borrowed from AutoZone for FREE: • Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as being incompetent. Please understand that I can only analyze and suggest based on the information that you provide.
Step One:
Perform a Thorough Visual Inspection
Do a thorough visual and "hands-on" underhood inspection before starting any diagnostic procedure! You can find the cause of many problems by just looking, thereby saving yourself a lot of time. Look first in the rear of the vehicle with the rear open. Under the plastic molding is a wire junction and this is where you'll begin your visual inspection. But first:
• Has the vehicle been serviced recently? Sometimes things get reconnected in the wrong place, or not at all. • Don't take shortcuts. Inspect hoses and wiring which may be difficult to see due to location. • Check sensors and actuators for damage. • Inspect the wiring harness wires for: - Damaged terminals. - Split or cracked connectors - Pinches and kinks. - Splits, cuts or breaks. • Inspect wiring for: - Contact with sharp edges. - Contact with hot surfaces, such as exhaust manifolds. - Pinched, burned or chafed insulation. - Proper routing and connections. • Check electrical connectors for: - Corrosion on pins. - Bent or damaged pins. - Contacts not properly seated in housing. - Bad wire crimps to terminals
If you didn't find the problem by doing the thorough inspection, proceed to the next section
Next: Perform a diagnostic Scan
Discussion: Late model vehicles are highly computer controlled to reduce emissions, maximize fuel economy and improve consumer comfort. The various control systems in vehicles are interrelated and controlled by multiple computers that constantly monitor vehicle performance through a myriad of sensors located throughout the vehicle. Based on information received, the computers adjust the vehicle performance through a series of valves, switches and motors.
A Scan Tool can be used to read and erase trouble codes, display, record and play back LIVE diagnostic data and perform other tests allowed by the vehicle maker. Scan tools that cover vehicles 1982 to present are available at your local auto supply dealer.
You don't indicate any diagnostic tests to date. A dealer or your local mechanic will charge $100-$200 to perform a diagnostic scan. However, AutoZone will provide a thorough scan for FREE.
If the fault is in the electrical system, the readout will be in the following range:
P0500 to P0599 This range of codes is related to electrical malfunctions. There could be a problem with the fuse box or electrical wiring, the idle control system, power steering, or cruise control could all be ailing.
If the fault is in the fuel management system, the readout will be in the following range:
P0100 to P0199 Meanings The computer codes ranging from P0100 to P0199 have to do with sensors within the engine's intake, exhaust, and carburetor. They may indicate a problem with the mass air flow sensor, the oxygen sensor, the oil temperature sensor, the fuel pump, or the fuel pressure sensor. In all these cases, the sensors are sending feedback to the PCM which is outside of normal threshold values, indicating that the sensor could be broken, or there could be a problem in the engine's functioning which would cause these values to be recorded.
Anyone who tells you that a modern vehicle can be diagnosed without a scanner with the problems you have set forth is a fortune teller or merely guessing. You car has a computer and memory and probably knows exactly what the problem is. That on-board computer is just waiting for you to ask, "What's wrong".
All the best,
Ben

Hi,

My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave' for today.

As you evaluate my advise.solutions and suggestions, there are a few things you must keep in mind:

• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew. I can only react to the information that you provide. So please judge my suggestions accordingly.
• A thorough diagnostic approach involves the use of technical equipment, such as voltage meters. scanning equipment and other sophisticated devices. Diagnostic tools can be borrowed from AutoZone for FREE:
• Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as being incompetent.

Subject: Engine starts, cuts off, and will not restart.

Customer's exact description: have changed the module, crank sensor and distibuter and still no spark. I am told now its the pcm. I looked under the dash on the drivers side and its not there.

Discussion: The customer has only described the vehicle as a Ford. I've not been provided with a model and year or even the type of vehicle (Is it a truck?) Late model vehicles are highly computer controlled to reduce emissions, maximize fuel economy and improve consumer comfort. The various control systems in vehicles are interrelated and controlled by multiple computers that constantly monitor vehicle performance through a myriad of sensors located throughout the vehicle. Based on information received, the computers adjust the vehicle performance through a series of valves, switches and motors.

Additionally, many vehicles have a variety of modules, e.g., ignition control module, powertrain control module (PCM), etc. You changed 'the module' but which one?

The customer doesn't indicate any diagnostic tests to date. A dealer or your local mechanic will charge $100-$200 to perform a diagnostic scan. However, AutoZone will provide a thorough scan for FREE. All of the suggestions cited below will require the use of a code scanner or a code reader.

This is how your problem is solved in my shop. Out of the box, I'd say that you have a problem with the electrical management system or one of the system sensors that is causing the on-board computer to make adjustments as best it can. Anyone who tells you that a modern vehicle can be diagnosed without a scanner with the problems you have set forth is merely guessing. You car has a computer and memory and probably knows exactly what the problem is. That on-board computer is just waiting for you to ask, "What's wrong".

This is where you'll start.

Perform a diagnostic code scan. Get back to me with the readout and the model and year of your vehicle.

Be advised that the approach you're taking will eventually solve the problem as you constantly add parts. But at what cost? Depending upon the year and model of the car in question, you would have to replace the ignition control module, coils, camshaft sensor, In fact, your problem may be nothing more than a $10 relay or a malfunction in the anti-theft deterrent system.

Sorry that I can't be more specific but I can only work with the information provided. Don't worry, I'll solve your problem.

All the best,

Ben

Does a jaguar gearbox fault indicate transmission fluid needs to be changed or that it is low?


it doesnt indicate that it needs a tranny flush thats for sure ,could need topping up though ,try disconnecting the battery both terminals and joining them together for a few minutes to see if it clears the fault ,if it but light comes on when driven then return vehicle to a jaguar dealer as it could be a computer fault and the software is encrypted so its a dealer only diagnostic machine ,Sorry to disappoint you here with no quick and easy answer ,The best models of this car are the diesel turbo with manual transmission ,now these cars do hold their value here in spain
