ETrainer (P/N ETR1000)

Automotive Test Solution's ETRAINER™ with FAULTMASTER™ Technology has solved America's problem of training both today's and tomorrow's mechanics to understand and repair automotive computer systems. This stand-alone automotive simulator features all major electrical engine components interacting with each other, just as they do in an actual running engine! When a fault or failure is programmed into the ETRAINER at the touch of a button, the PCM commands and wave forms respond as they would in a typical engine with the problem. Using ETRAINER , the beginner as well as the advanced student, will soon be able to troubleshoot computer problems like a pro! ETRAINER is the most unique electrical simulator available today!

Automotive Test Solution's microprocessor was specifically designed and programmed for the ETRAINER magic black box! The exclusive FAULTMASTER Technology has been in development for more than six years years and is now ready to teach America's mechanics how to troubleshoot and repair automotive electronics.

FAULTMASTER Technology can simulate hundreds of faults which include: power circuit, ground circuit, open circuit, short circuit, battery, charging system, lamp, relay, electric motor, no cranking, no start, OBDII coded drivability, no coded drivability, and intermittent drivability faults as well as emission and data bus failures, PCM failures and PCM resets... and many more simulated faults, failures and problems.

ETrainer’s RS-232 port enables future updates to be downloaded into ETrainer’s advanced microprocessor using your computer and cable (supplied with ETrainer).

The first stage of training are the light circuits. Lamp luminosity is the best way to illustrate both Ohm's and Kirchhoff's law. Real problems with the lamp circuit can be viewed visually on the board by lamp brilliance (see photo left). Then the student checks the circuit with a DVOM which reinforces the basic electrical laws. Once the student is familiar with these basic laws then they can move on to ETrainer's more challenging electrical relay motor circuits (see overview photo, center section)

A DVOM and oscilloscope can be used on all circuits and test points.

The AMP probe wave forms include: Injector, EGR Solenoid, Ignition Coil, & Fuel Pump and they can all be faulted.

There are 101 test point positions on the ETrainer board and they are laid out like a wiring diagram in an electrical schematic.

These test points are designated by three colors: Black (ground), Red (power) and White (inputs and outputs).

Actual engine parts are used on the simulator and can be tested just as in an actual vehicle.

• Engine Coolant Temperature Sensor, a 2-wire type negative thermistor coolant sensor.
• Fuel Injector is saturation type which is controlled by mathematical calculation program - it also has a peak and hold pattern.
• Exhaust Gas Recirculation EGR Solenoid, it is controlled by PCM duty cycle.
• Jumper Pin opens and closes circuit for diagnostic procedure.

• Crank Trigger is a magnetic reluctance position sensor.. Cam Trigger is a hall effect position sensor.. both triggers can be hand turned or engine driven.
• Ignition Module is an electronic spark control module.
• Program Control Knob controls the display panel reading.
• Spark Plug, weak or no spark can be seen in the open gap.
• O2 Heater relay, controlled by PCM, pulls primary circuit to gnd.
• O2 Sensor, heated zirconia Oxide sensor, realistc wave form.
  Engine Coolant Control Knob controls ECT input to the PCM.

• Throttle Position Sensor, three-wire potentiometer, signals throttle angularity.
• Fuel Pump Relay, controlled by PCM or by toggle switch, PCM sends battery voltage to the primary circuit.
• Fuel Pump Motor, controlled by relay circuit, simulates any type relay motor.
• Manifold Absolute Pressure Sensor, strain gauge type sensor, sends realistic voltage wave form to PCM.

• Programing Control Panel, four buttons used for controlling the input of hundreds of faults, problems, failures and resets.
• Ignition Coil, step up transformer controlled by the ignition module.
• Toggle Switches, pull up / pull down circuits.

• Ignition Key
• RS-232 Input
• Battery, voltage can be controlled for faults.

DIAGNOSTIC BUTTONS:

Sounds:
The sound you heard when this page was opened is what the distributor motor and fuel injector sound like when the ETRAINER is at Idle. Refresh page to hear again. The sound may not be heard on some web browsers.
