NOTE While cranking engine with bad or discharged batteries, VTM may lose power and come on again after cranking has stopped, displaying -----.

Then set VTM TEST SELECT switches to 15. Press and release TEST. When GO appears on display, crank engine until OFF or E013 appears on display. Be sure to return ignition key switch to off position. Display should indicate (TBD). a. If display indicates (TBD), compression unbalance is okay. Go to step 7 below. b. If display indicates a number higher than (TBD), notify next higher maintenance level (additional tests must be performed). C . If FAIL is displayed, compression is too far unbalanced to be measured using STE/ICE. Notify next higher maintenance level (additional tests must be performed). d. If GO appears, repeat this step. e. If E013 is displayed, test data cannot be analyzed due to weak batteries or interrupted cranking during test. Correct weak bat- teries by charging them, then repeat this step. If E013 message persists, after two tests, notify next higher maintenance level to perform compression test using pressure gage. 3-212
