How to Diagnose a Misfire (a ScannerDanner Premium training video)
2005 GM Bonneville 3800 with a constant misfire. Paul uses the uScope
- setting a scope trigger at timestamp 5:20
- connecting a capacitive pick-up to a pug wire at timestamp 8:04
- causes of low firing KV on a snap throttle starts at timestamp 10:44
- how a waste spark coil can fire on only one tower at timestamp 17:30
- setting a trigger on a scope to capture snap throttle events at timestamp 23:14
- adjusting voltage scales and time base at timestamp 26:20
- reserve coil oscillations and why they are important at timestamp 29:35
- burn time of a spark plug at timestamp 31:55
- misfire data and how it is calculated by the computer at timestamp 36:17
- ignition primary current waveform analysis at timestamp 40:26
- more scope trigger, time-base and voltage settings at timestamp 43:24
- coil primary turn-on oscillations at timestamp 46:42
Inverting, Freezing, and Measuring with the uScope
At time stamp 11:40, ScannerDanner uses the uScope to current ramp a coil on a 99 Honda Civic No Spark Diagnosis. He inverts the signal and adjusts time and trigger level to capture the signal.
At 16:20 he presses the "A" button (on the top right) to "HOLD" the display. He then changes time and amperage scales to zoom in and out of the signal and uses the cursors to get ΔT and ΔV (Amps). This can be done on a live signal and while on "HOLD".
Later in the video, timestamp 24:20, he shows how to change the "Horizontal Position" of the signal to the left, by doing this he is able to see the position of the cursors on the waveform without the menu obstructing the view.
A "neat trick" with the uScope
ScannerDanner uses a "neat trick" of the uScope to capture a misfire event during a snap throttle test on a 2002 Ford Taurus with a P0301 code, Cylinder 1 Misfire Detected.
He sets the trigger type to SING so the uScope will Auto-Hold after the trigger level has been met. This means the scope will not display a waveform until after trigger level has been met. And once trigger has been met the scope will display and freeze the waveform. In the video, ScannerDanner refers to it as a "Single Shot".
Comparing Open Plug Wires
ScannerDanner uses AES' Universal Secondary Test Lead Kit (the Paddle Probe) to compare an open plug wire to a known-good on a Dodge Caravan 3.8. NOTE: The Paddle Probe used in the video has a BNC connector and Paul uses an adapter to connect it to the uScope. The Paddle Probe included with the uScope kit does not require an adapter.
Secondary and Relative Compression
ScannerDanner verifies a misfire with no trouble codes and no mode $06.
