  • Page 2 Introduction Thank you for your purchase of the LS1M Scanner. The LS1M Scanner is a scan tool that can retrieve engine parameters and trouble codes from GM vehicle using the VPW OBD-2 protocol. That includes most GM cars & trucks from 1996 to 2006. To verify compatibility of your vehicle to the LS1M scanner, look for the diagnostic connector under the dash, on the driver’s side.
  • Page 3 Also available is a custom PDA for use with the LS1M scanner. It comes with a PDA, USB hotsync cable, serial hotsync cable, home charger, car charger, Getting Started guide and a PDA software CD. Serial Cable Car Charger Home Charger USB Cable Getting Started PDA Software CD...

  • Page 5: Charging The Pda

    Power Mute LS1M Icon Shift Page up/down Charging the PDA Your PDA has been fully charged before shipping, so it shouldn’t require any charging before first use. To recharge it, plug the USB cable into the bottom connection on the PDA, and plug the other end into any USB port or to the PDA home charger.

  • Page 6: Using The Stylus

    Using the Stylus For clicking buttons on a PDA, you use a stylus, which is just a plastic pointer. The stylus should be in its holder on the back of the PDA. To use it, pull it out & tap the display where you want to “click”. If you don’t have the sounds silenced, you should hear a little ticking noise when you click, and whatever icon you click on will cause its associated program to run.

  • Page 8 Installing LS1M Synchronizer To enable you to save logs to text files on the PC, you must install LS1M Synchronizer. First install Palm Desktop as described above. If you already have Palm Desktop installed, verify it’s version 4.1 or better (select to Help- >About Palm Desktop).

  • Page 9: Resetting The Pda

    and another dialog box “LS1M Sycnchronizer” will pop up, which is what you use to save logged data from the PDA to the computer. See “Exporting Logs to the PC” on page 18. Resetting the PDA PDA’s are little computers, and like computers hang up sometimes, every once in a while the PDA can get “stuck”. There’s usually an error message on the screen, or the screen simply freezes.

  • Page 13 The first page is filled with some of the most common, basic engine parameters, from temperatures & ignition advance, to fuel trims & O2 sensor values. The second page is configured for just ignition voltage. This can be useful to determine the state of health of your battery.
  • Page 14 Page 5 has some of the diagnostic parameters. MAF and MAFF show mass air flow sensor output. MISP and MISR are used for misfire diagnosis. MAP shows the manifold air pressure, while IAC shows the idle air controller position in counts, and TPSV shows the throttle position switch output in volts.
  • Page 15 Pick a parameter from the drop-down list, pick a condition, then enter a value. In the example on the left, all scans will be shown that contain ignition timing advance greater than 25 degrees. In the example on the right, scans will be filtered starting when the throttle is over 90% open and stopping when the SPD reaches 70 mph.

(These lists are kept separate from the Scan screen, so any changes you make here only affect the Auto-Log screen.) Click Save or Cancel to get back to the main screen.
  • Page 18 In this example, the engine coolant temperature reached a maximum of 209.9 degrees F, the average intake air temperature was 89.9 degrees F, and the maximum vehicle speed was 39.3 MPH. Click on a parameter name or the word “Max” to change the display. Note that only the parameters that were selected to log will be included here. For instance, if KR (knock retard) was not included in parameter list 1, then you can’t view the Min, Max or Avg value of KR during this run.
  • Page 19 Exporting Logs to the PC Once logs have been saved on the PDA, you can export them to files on your PC during a hot-synch operation. This requires that Palm Desktop 4.1 and the LS1M Synchronizer are both installed on your computer. See the section below on Palm Desktop for installation instructions.
  • Page 20 EFILive format is for compatibility with the EFILive scan tool program. Note that if you selected metric units on the LS1M Config screen, then metric units will be saved to the log file by the synchronizer. Clicking the other tabs across the top of the synchronizer window – Ltrims, Accel Tests, Trouble Codes – will show the saved data from the other scan screens.
  • Page 21 Click the saved entry at the top. Detailed information will be displayed in the bottom part of the screen. Use the scroll bar to the right of this data to page down & see all the collected cell values. The Clear Log button will erase all saved LTrim collections.

  • Page 24: Software Upgrades

    Software Upgrades Updates to the LS1M software are free for the life of the scanner. Information on revisions will be available on the LS1M web site: http://www.LS1M.com The LS1M program, like most all PDA programs, consists of one file (LS1M.PRC). This program can be installed just any other 3 -party software, with the Palm Desktop, or the downloaded setup file can be used instead.

  • Page 25: Getting Support

    Click the “Add…” button & navigate to the directory where the new LS1M.PRC is. Select the file LS1M.PRC and click “Done”. Now, the next time a hot-synch is performed, the new version of LS1M will be installed. To verify that the new version actually got installed, start LS1M on the PDA and note the version number at the bottom of the screen.

  • Page 26: Scan Parameters

    Appendix Scan Parameters Please note that not every vehicle will support every parameter. For example, most V6-equipped vehicles do not have a passenger-side O2 sensor; therefore, codes such as LFT2 & O2R will return “T.O.” (timeout). The engine type selected on the Config screen will also determine which parameters are available on the screen when you’re configuring the scanner.
  • Page 27 Enhanced parameters are additional data that can be scanned from most late-model GM vehicles. The LS1 and L67/L36 support all of these listed below.
