  • Page 48: The Graphing Multimeter

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE GRAPHING MULTIMETER Throttle Position Sensor (TPS) In this portion of the presentation we are going to go a little deeper into the Graphing Multimeter function of the MTS 5200. Pictured right you can see that we have connected the lab scope to a demonstration board.
  • Page 49 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE GRAPHING MULTIMETER Throttle Position Sensor (TPS) A normal TPS sensor will have a low voltage with the throttle released and voltage going higher as the throttle is depressed. Pictured above is a waveform captured from the screen of the lab scope.
  • Page 50 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE GRAPHING MULTIMETER Throttle Position Sensor (TPS) Pictured above is the same waveform from the demonstration board but the glitch switch on the board has been turned ON. Note that the pattern now has three distinct drops in voltage indicated by the three lines going down in the pattern.

  • Page 51: Frequency

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE GRAPHING MULTIMETER Frequency We just looked at a voltage waveform for a TPS using the MTS 5200 connected to a demonstration board. Now let’s look at a frequency waveform. A frequency waveform would be useful in diagnosing such things as a MAF sensor on Ford vehicles or even a CKP signal during a no start condition.

  • Page 52: Coolant Sensor

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE GRAPHING MULTIMETER Frequency For this type of signal it is important to keep an eye on the minimum and maximum values. This is because if you had a Ford vehicle that had a hesitation problem, you would look for the minimum signal to fall to 0.0Hz.

  • Page 53: The Lab Scope (Square Wave With & Without Glitch)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (SQUARE WAVE WITH & WITHOUT GLITCH) Using the lab scope on the connected to the variable frequency signal terminal of the demonstration board you can see that we have a waveform on the screen. Also note that the voltage goes off of the screen.
  • Page 54 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (SQUARE WAVE WITH & WITHOUT GLITCH) Using the signal finder function is one way to set the scope up quickly, however it may not give you the display that you actually want. If we use the Component Selection function and actually choose the sensor that we are testing, we can set the scope up to view the patterns exactly how we want to.

  • Page 55: Triggers

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (SQUARE WAVE WITH & WITHOUT GLITCH) Triggers The MTS 5200 has a set of trigger controls that determine the exact instant the trace begins the sweep across the screen. If a trigger is set at a specific voltage level, and the signal being sampled achieves that trigger level voltage, then the MTS 5200 displays the signal.
  • Page 56 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (SQUARE WAVE WITH & WITHOUT GLITCH) Triggers Trigger edge set to “Rising” position A good way of understanding trigger points is this. Imagine that you are driving down the road and you have a camera in your hands and you want to take a series of pictures.
  • Page 57 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (SQUARE WAVE WITH & WITHOUT GLITCH) Triggers Single Shot Trigger Single Shot trigger is used when you want to capture a certain characteristic of a known signal. If the signal under examination does not reach your trigger threshold setting, the MTS 5200 does not display any signal.

  • Page 58: The Lab Scope (Injector Signal)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (INJECTOR SIGNAL) We have moved our test lead on the the demonstration board to the injector signal terminal. In the Signal Finder mode we have also selected Fuel Injectors from the Component Selection menu.

  • Page 59: The Lab Scope (Missing Trigger)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (MISSING TRIGGER) An important thing we need to cover before moving on to the hands on portion are missing triggers (missing events). Depending upon how you set up your scope you may not be catching what you think that you should be catching.

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale THE LAB SCOPE (RECORDING & SCREEN CAPTURE SAVING) The file management system of the MTS 5200 allows you to view and manipulate saved images, snapshots, and text files by using the following functions: •...

  • Page 61: 1995 Nissan Ignition Case Study

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale 1995 NISSAN IGNITION CASE STUDY Now that we have covered the navigation and functions of the MTS 5200 it is time to take a look at the power it has when used in your diagnostic strategy. Up until now we have only demonstrated how to use the lab scope using one channel.
  • Page 62 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale 1995 NISSAN IGNITION CASE STUDY Coil Power (green) Coil Control (red) Coil Ground (blue) Coil #2 (yellow) Now that we know that the PCM is not commanding the coil to fire we have to find out why. The instructor has connected all four of the channels of the scope to the ignition coil as shown in the screen capture above.
  • Page 63 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale 1995 NISSAN IGNITION CASE STUDY The first sensor that was the easiest to get to was the CMP sensor. As you can see in the waveform above, that at no time did the CMP sensor signal drop out, but the ignition pattern at the bottom is still dropping out intermittently.
  • Page 64 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale 1995 NISSAN IGNITION CASE STUDY Crank Signal (blue) Signal (red) Since we have determined that the problem is NOT with the CKP sensor or the CMP sensor, we need to look closer at the relationship between the camshaft and the crankshaft. Pictured above is a waveform overlay that has the crankshaft signal in blue and the camshaft signal in red.
  • Page 65 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale 1995 NISSAN IGNITION CASE STUDY Pictured above is a screen capture of a CMP/CKP signal waveform taken from the IATN website. This waveform is showing us what a known good waveform for each looks like along with the relationship between the two.

  • Page 66: Live Vehicle Testing (Secondary Ignition Cop Wand)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (SECONDARY IGNITION COP WAND) In this portion of the presentation we are going to take a look at some of the basic signals and circuits underneath the hood of a live vehicle. We will use the MTS 5200 and demonstrate how you connect it to the most common signals that you will be testing.
  • Page 67 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (SECONDARY IGNITION COP WAND) You can see in the screen capture above that this vehicle has a multi-strike ignition system as indicated by the three firing patterns in the waveform. The first thing we need to look at is the primary (1st strike) ignition pattern of each ignition coil.

  • Page 68: Live Vehicle Testing (Secondary Ignition Cop Loop)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (SECONDARY IGNITION COP LOOP) Many times on vehicles that have COP ignition systems it is difficult to spot a misfire at idle. Normally misfires on COP ignition vehicles occur when the vehicle is running down the road. To detect misfires while driving the vehicle we want to use a COP loop.
  • Page 69 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (SECONDARY IGNITION COP LOOP) You can see in the screen capture above that the scope has been set up with the trigger point on the leading edge of the waveform. Also note that the Time/Div has been increased giving more resolution to the pattern for easier viewing.

  • Page 70: Secondary Ignition Testing With The Lab Scope

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale SECONDARY IGNITION TESTING WITH THE LAB SCOPE So far we have covered two ways to diagnose secondary ignition problems. We have used the COP wand and the COP loop but there is also another method you can try, and that is using the 4 channel lab scope to diagnose the ignition patterns.

    COP loop. Keep in mind that to use this method you need to know what cylinder is misfiring. This is a completely different subject that is covered on other AVI training programs. Visit www.auto-video.com or call 1-800-718-7246 for more information about Misfire Diagnostics.

  • Page 72: Live Vehicle Testing (Fuel Pump)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (FUEL INJECTORS) The screen capture above illustrates what a known good injector pattern looks like on our subject vehicle. As with the previous ignition patterns, you can switch between channel 1 and channel 2 to compare signals.
  • Page 73 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (FUEL PUMP) You will get very good at using this current probe as you get better at using your lab scope. You need to get in the habit of testing every fuel pump on every high mileage vehicle that comes through your shop.
  • Page 74 BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (FUEL PUMP) Using a suitable scan tool we can duty cycle the fuel pump without the vehicle running, and analyze the waveform on the lab scope. If your scan tool is not capable of this, you may have to find another way to command the fuel pump on.

  • Page 75: Live Vehicle Testing (Tps - Gmm)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (TPS - GMM) For this portion of the presentation we are going to take a closer look at the throttle position sensor (TPS). The TPS is a very common sensor and when it fails you will usually have a hesitation or problems that are very similar to hesitations.

  • Page 76: Live Vehicle Testing (Recap)

    BOSCH MTS 5200 LAB SCOPE Presented by Bob Pattengale LIVE VEHICLE TESTING (TPS - GMM) In the screen capture above you can see that as we exercise the throttle from WOT to closed, the signal trace on the screen follows the movement indicating that the TPS is working correctly. There is one thing to keep in mind here.
