DTC P0AB7: Inspection

Rear Engine Mount Actuator Component Inspection 

NOTE: 

• Be sure to use a digital volt/ohm meter (DVOM) capable of reading 0.01 ohms change of resistance.
• Be sure to zero the meter before checking the engine mount actuator.

Test Procedure 

• Preparation
  • Rear engine mount actuator connector (2P): disconnected
• Procedure
  • Perform the inspection according to the following chart.

			(Disconnected) Rear engine mount actuator connector (2P) male terminals
		IG Mode	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	Actuator internal circuit inspection	OFF		About 1.37 - 1.51 ohms (at 68°F (20°C))

Results 

• If it is abnormal, there is a problem with the rear engine mount actuator.

RR_ACM_SOL+ [RR_ACM_SOL+ (RR_ACM)], RR_ACM_SOL- [RR_ACM_SOL- (RR_ACM)], PGND Circuit Inspection 

Test Procedure 

• Preparation
  • Rear engine mount actuator connector (2P): disconnected
  • Engine mount control unit connector (16P): disconnected
• Procedure
  • Perform the inspection according to the following chart.

			(Disconnected) Rear engine mount actuator connector (2P) female terminals	(Disconnected) Engine mount control unit connector (16P) female terminals

		IG Mode	Courtesy of HONDA, U.S.A., INC.	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	RR_ACM_SOL+ [RR_ACM_SOL+ (RR_ACM)] open wire inspection	OFF			There is less than 1 ohms
	RR_ACM_SOL- [RR_ACM_SOL- (RR_ACM)] open wire inspection	OFF			There is less than 1 ohms
	PGND open wire inspection	OFF			There is less than 1 ohms
	Refer to the Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	RR_ACM_SOL+ [RR_ACM_SOL+ (RR_ACM)] shorted to ground inspection	OFF			Not shorted
	RR_ACM_SOL- [RR_ACM_SOL- (RR_ACM)] shorted to ground inspection	OFF			Not shorted

Results 

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

Engine Mount Control Unit Inspection 

Test Procedure 

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

Results 

• There is a problem with the engine mount control unit.
