NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.
- Information marked with an asterisk (*) applies to rear active control engine mount (ACM) actuator.

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Do the VTEC TEST in the INSPECTION MENU with the HDS.
4. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0A14 and/or P0AB6* indicated?

YES - Go to step 5.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the engine mount control unit and the active control engine mount (ACM) actuator.

5. Turn the ignition switch OFF.
6. Disconnect the front active control engine mount (ACM) actuator (rear active control engine mount (ACM) actuator)* 2P connector.
7. Disconnect the engine mount control unit 20P connector.
8. Turn the ignition switch ON (II).




9. Measure voltage between body ground and the appropriate engine mount control unit 20P connector terminal (see table).

Is there battery voltage?

YES - Repair short to power in the wire between the engine mount control unit and the active control engine mount (ACM) actuator, then go to step 13.

NO - Go to step 10.

10. Turn the ignition switch OFF.




11. Check for continuity between engine mount control unit 20P connector terminals No. 9 (No. 1)* and No. 20 (No. 10)*.

Is there continuity?

YES - Repair short in the wire between the engine mount control unit No. 9 and No. 20 terminals (No. 1 and No. 10 terminals)*, then go to step 14.

NO - Go to step 12.




12. Check the resistance between active control engine mount (ACM) actuator 2P connector terminals No. 1 and No. 2.

Is there about 0.75- 1.15 Ohm?

YES - Replace the engine mount control unit, then go to step 14.

NO - Replace the front engine mount or rear engine mount, then go to step 14.

13. Turn the ignition switch OFF.
14. Reconnect all connectors.
15. Turn the ignition switch ON (II).
16. Reset the PCM with the HDS.
17. Do the PCM idle learn procedure
18. Do the VTEC TEST in the INSPECTION MENU with the HDS.
19. Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?

YES - If DTC P0A14 and/or P0AB6* is indicated, check for poor connections or loose terminals at the engine mount control unit and the active control engine mount (ACM) actuator, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.

NO - Troubleshooting is complete.
