CCV_GND Open Wire Inspection 

NOTICE: 

Before disconnecting the PCM connector, jump the SCS line with the HDS, and wait more than 1 minute.

Test Procedure 

• Preparation
• • -

    EVAP leak check module 8P connector: disconnected

  • -

    PCM connector B (72P): disconnected

• Procedure
• • -

    Perform the inspection according to the following table.

			(Disconnected) EVAP leak check module 8P connector female terminals	(Disconnected) PCM connector B (72P) - Refer to: PCM Connector for Inputs and Outputs (3.0L Engine) or PCM Connector for Inputs and Outputs (2.0L Engine) female terminals

		IG Mode	Courtesy of HONDA, U.S.A., INC.	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	CCV_GND open wire inspection	OFF			There is less than 1 Ohm

Results

Power Distribution Module Inspection 

Test Procedure 

• Install a known-good power distribution module 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 power distribution module must be faulty.

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.
