Playback of Stored PIDs Procedure

NOTE:
- Look for abnormal behavior or values that are clearly incorrect. Inspect the signals for abrupt or unexpected changes.
- Look for agreement in related signals.
- Make sure signals act in proper sequence.

1. Select VIEW RECORDER AREAS.
2. Select a view area.
3. Select up to the four PIDs to review in the table format or two PIDs to review in the graph mode.




4. Table format: Scroll through the PID data while analyzing the information. Look for sudden drops or spikes in the values.
For example:
Notice the major jump in the TP voltage while scrolling through the information. This example would require a smooth and progressive throttle pedal travel during a key ON and engine OFF mode.




5. Graph format: Scroll through the PID data while analyzing the information. Look for sudden drops or spikes in the linear lines showing the transformation of values to the line graph.
