Depending on the position of the relay and the ECL bolt when the key (ignition switch) is first turned to the ON position, you may receive the message Pull Key and Wait 10 Sec.

If you do NOT receive this message, the ECL and relay ARE synchronized. No further action is required.

If you DO receive this warning message, the ECL and relay are NOT synchronized. To synchronize, turn the ignition switch to the OFF position and REMOVE THE KEY from the switch (lock cylinder). Wait a MINIMUM of 10 seconds, re-insert the key, and turn to the ON position. From this point on, the ECL and relay should be synchronized.
