Compression Test with Engine Cranking
Setup:
Remove spark plugs
Install suitable compression test gauge on the first cylinder to be tested
Note: If communication is lost or the Exit button is selected, the vehicle power mode must be cycled off then back to Service Power Mode to re-enter the test.
Test sequence:
When the Crank button is selected, this test will set the throttle blade to 100%, disable fuel injectors, and disable spark. The engine will rotate briefly after a slight delay.
Record the result, then move the gauge to the next cylinder to be tested. Repeat this sequence until all cylinders have been tested. Then select Exit.
