Automotive sensor simulator and signal generator with additional accessories

Since its release in 2012, the AutoSim sensor simulator has proven itself extremely popular with both technicians and professional diagnosticians thanks to its friendly user interface, attractive and reliable operation.

Eight years after the release of the original model, Ditex presents the second generation AutoSim Pro. Distinguished by its completely updated design and significant functional improvements, the AutoSim Pro Automotive Sensor Simulator from Ditex is a very useful tool suitable for both cars and trucks applications in a variety of working situations. This advanced sensor simulator creates an electrically equivalent system to simulate the sensors and actuators found on an actual vehicle.

Master kit includes the most frequently used additional accessories to the already popular AutoSim Pro Automotive Sensor Simulator from Ditex.

See the Autosim Pro product description for the main details.

  • Handheld standalone device
  • Intuitive operation via function keys;
  • Ultra-fast boot time;
  • Excellent industrial design;
  • Operates on both 12 and 24 Volt electrical systems;
  • Illuminated 2.4" TFT LCD 320х240 display for optimum visibility;
  • Protection against reverse polarity connection;
  • Low distortion factor and high signal-to-noise ratio for brilliant signals;
  • Adjustable frequency range from 0.1 Hz to 10 kHz;
  • Generating variable power PWM signals up to 4 A;
  • One-wire hook-up PWM output;
  • Precise DC voltage source;
  • Internal Micro SD card for firmware updates.
  • Simulates actual working condition of the most automotive sensors;
  • Efficient fault elimination without replacing parts "on suspicion";
  • Simulates O2 sensor signals: Zirconia and Titania;
  • Checking of basic ECU operation;
  • Controlling the output signal allows to check the ECU response and operation;
  • It can drive ECU into “open” or “closed” loop;
  • Activation of a large number of actuators;
  • Variable adjustable voltage output from 0 to ±12 volts;
  • Simulates crank and cam sensors inductive and hall;
  • In both crank and cam modes you are able to adjust the number of teeth and the missing teeth.

Important note: Because of lithium-ion battery shipping restrictions, we do not include CR2032 lithium-ion battery inside in the air mail post packages. When you receive the tester, you have to buy a Li-Ion battery type CR2032 yourself and put it into battery holder socket inside the CarScope i-Tester. To do so, you should unscrew and remove four screws to open the bottom cover. We apologize for the inconvenience!
