⁽¹⁾	Spare for revolution sensor

⁽²⁾	Spare for throttle angle 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-diagnostics; if self-diagnostics are not started, it is judged that there is some kind of error.

⁽⁵⁾	CAN communications.
