Technician Tips

• Utilize the searchable database by always saving test results and filling in all applicable fields so that a search can be used to recall data at a later time. If needed, the searchable database can be used to compare a similar vehicle and symptom.

• Use the print capabilities of the On Car Injector Flow Bench software to document the diagnosis and repair for the customer.

• Some vehicles have batteries that are inaccessible or in the rear, most manufacturers on this type of set up provide an easier jumper cable point, which can provide a power and ground source.

• The On Car Injector Flow Bench can be used to command a PWM* controlled fuel pump “on” for pinpoint tests when a factory Scan tool is not available. These PWM fuel pumps are duty cycle controlled and can not be hot-wired.
  * Pulse Width Modulated

• The On Car Injector Flow Bench can be used, as a fuel injector inductance tester required by a major Auto Manufacturer. (GM Kentmoore J 39021)
  

• Use the “Drain Tester” selection to depressurize the fuel system before removing the tester to avoid fuel spray.
  

• The On Car Injector Flow Bench can be used separately, as a fuel pressure gauge with min/max capabilities. This means you do not need to physically watch the fuel pressure at all times for those intermittent pressure drops.
  

• A large percentage of GM trucks use mechanical poppet valves after the electrical injector that can stick closed causing a cylinder miss-fire, even a no start. The On Car Injector Flow Bench has a special SCPI test function for this type of fuel system.
  

• Not sure if you hooked up the connectors to the injectors in the proper order? To verify you are condemning the correct injector you can use the injector locator function to pinpoint the proper injector location.

• How do you know which injector is bad?
  Use the injector locator function.

• Do I have to have a computer in order to use this tool?
  The vehicle injector flow rates can be determined without the use of a computer, however to view injector specifications, database and print test reports you will need a computer.
