		IG Mode	Courtesy of HONDA, U.S.A., INC.	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	RF_VCC1 open wire inspection	OFF			There is less than 1 Ohm
	RF_DATA1 open wire inspection	OFF			There is less than 1 Ohm
	RF_GND open wire inspection	OFF			There is less than 1 Ohm
	NOTE:  Refer to: Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	RF_VCC1 shorted to ground inspection	OFF			Not shorted
	RF_DATA1 shorted to ground inspection	OFF			Not shorted
	RF_GND shorted to ground inspection	OFF			Not shorted

Results 

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

2-Way Transceiver Inspection 

NOTE:  Since there is no direct method to test the inspection item, troubleshooting is performed using a known-good component.

Test Procedure 

• Install a known-good 2-way transceiver and attempt to reproduce the failure.

Results 

• If the failure is reproduced, there is a problem with other related components.
• If the symptom/DTC goes away, the 2-way transceiver must be faulty.

Roof Antenna Inspection 

Test Procedure 

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

Results 

• There is a problem with the roof antenna.
