	VCC2 open wire inspection	OFF			There is less than 1 Ohm
	TD_CAM open wire inspection	OFF			There is less than 1 Ohm
	SG2 open wire inspection	OFF			There is less than 1 Ohm
	NOTE: Refer to the Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	TD_CAM shorted to ground inspection	OFF			Not shorted

Results 

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

PCM Inspection 

Test Procedure 

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

Results 

• There is a problem with the PCM.
