Finding irregular signals
WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
While referring to, 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
