DTC P0A15

DTC P0A15  : Front Engine Mount Actuator Control Circuit Low Current

DTC (Engine Mount Control Unit)

1. Problem verification

   - 1. Turn the vehicle to the ON mode.

   - 2. Clear the DTC with the HDS.

   - 3. Start the engine, and let it idle 20 seconds.

   - 4. Check for Pending or Confirmed DTCs with the HDS.

   P0A15 Front Engine Mount Actuator Control Circuit Low Current

   Is DTC P0A15 indicated?

   YES 

   Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the engine mount control unit, the front engine mount actuator, and body ground G201.

2. Front engine mount actuator check

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Disconnect the following connector.

   Front engine mount actuator 2P connector

   - 3. At the front engine mount actuator side, measure the resistance between test points 1 and 2.

   NOTE: Zero-out the meter before testing to adjust the meter to the test leads.

   Is there about 1.37- 1. 51 Ω (68 °F/20 °C)?

   YES 

   Go to step 3.

   NO 

   Replace the front engine mount .

3. Open wire check (PGND line)

   - 1. Disconnect the following connector.

   Engine mount control unit 16P connector

   - 2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Front engine mount actuator 2P connector: disconnected
   	Engine mount control unit 16P connector: disconnected
   Test point 1	Engine mount control unit 16P connector No. 4
   Test point 2	Body ground

   Is there continuity?

   YES 

   Go to step 4.

   NO 

   Repair an open in the PGND wire between the engine mount control unit and ground G201.

4. Shorted wire check (ACM SOL F+, ACM SOL F- lines)

   - 1. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Front engine mount actuator 2P connector: disconnected
   	Engine mount control unit 16P connector: disconnected
   Test point 1	Engine mount control unit 16P connector No. 3 and No. 5
   Test point 2	Body ground

   Is there continuity at one or both testing positions?

   YES 

   Repair a short to ground in the ACM SOL F+ wire and/or the ACM SOL F- wire between the engine mount control unit and the front engine mount actuator.

   NO 

   Go to step 5.

5. Open wire check (ACM SOL F+, ACM SOL F- lines)

   - 1. Connect terminals A and B to body ground individually with jumper wires.

   Terminal A	Front engine mount actuator 2P connector No. 1
   Terminal B	Front engine mount actuator 2P connector No. 2

   - 2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Front engine mount actuator 2P connector: disconnected
   	Engine mount control unit 16P connector: disconnected
   	Front engine mount actuator 2P connector terminal No. 1: jumped to body ground
   	Front engine mount actuator 2P connector terminal No. 2: jumped to body ground
   Test point 1	Engine mount control unit 16P connector No. 3 and No. 5
   Test point 1	Body ground

   Is there continuity at both testing positions?

   YES 

   Check for poor connections or loose terminals at the engine mount control unit and the front engine mount actuator. If it is OK, replace the engine mount control unit .

   NO 

   Repair an open in the ACM SOL F+ wire and/or the ACM SOL F- wire between the engine mount control unit and the front engine mount actuator.
