			(Disconnected) TCM connector A (23P) female terminals	(Disconnected)Paddle shifter 4P connector male terminals
		IG Mode	Courtesy of HONDA, U.S.A., INC.	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	SUPP [PADDLE_SW_UP] open wire inspection*1	OFF			There is less than 1 Ohm
	SDNP [PADDLE_SW_DOWN] open wire inspection*2	OFF			There is less than 1 Ohm
	GND open wire inspection	OFF			There is less than 1 Ohm
	NOTE: Refer to the Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	SUPP [PADDLE_SW_UP] shorted to ground inspection*1	OFF			Not shorted
	SDNP [PADDLE_SW_DOWN] shorted to ground inspection*2	OFF			Not shorted

*1: Applies to the paddle shifter + (upshift switch) circuit*2: Applies to the paddle shifter - (downshift switch) circuit

Results 

• If abnormal, there is a problem in the circuit.

TCM Inspection 

Test Procedure 

• If the other inspection item(s) indicated a normal condition, then it is determined that the remaining TCM is the cause.

Results 

• There is a problem with the TCM.
