Finding Irregular Signals

While referring to 01-02-6 ON-BOARD DIAGNOSTIC TEST [LF], use the PID/DATA monitor and record function to inspect the input signal system relating to the problem.

Start the engine and idle the vehicle. You can assume that any signals that are out of specification by a wide margin are irregular.
When recreating the problem, any sudden change in monitor input signals that is not intentionally created by the driver can be determined as irregular.
