⁽¹⁾	Input by CAN communications.

⁽²⁾	If these input and output signals are different, the TCM triggers the fail-safe function.

⁽³⁾	Spare for vehicle speed sensor. A/T (revolution sensor)

⁽⁴⁾	Spare for accelerator pedal position signal

⁽⁵⁾	Used as a condition for starting self-diagnostics; if self-diagnosis are not started, it is judged that there is some kind of error.

⁽⁶⁾	Output by CAN communications.
