How to use the output test function



1. Make sure you are online with MaxxECU




2. Make sure outputs are activated as either Injector outputs or Ignition outputs for the output test function to work. In the above, green areas will work with output test, red will not.




3. Change output test settings, the above example will most likely work for most people. Found in Diagnostics --> injection and ignition output test.




4. Click the check boxes for the output(s) you are about to test, when done, press the start test button at the top, and press the same button when you want to stop the test output function.





The pulse single output test is very handy to use when troubleshooting wiring issues.
