⁽¹⁾	Spare for vehicle speed sensor. A/T (revolution sensor).

⁽²⁾	Spare for accelerator pedal position signal.

⁽³⁾	If these input and output signals are different, the TCM triggers the fail-safe function.

⁽⁴⁾	Used as a condition for starting self-diagnosis; if self-diagnosis are not started, it is judged that there is some kind of error.

⁽⁵⁾	Input by CAN communications.

⁽⁶⁾	Output by CAN communications.
