terminals and creating poor contact with the battery. To eliminate this concern, the structure in the remote transmitter has
been modified to reduce the deformation of the electrical terminals.
Symptom 4-5: This may be caused when excessive load is applied to the remote transmitter, creating a gap around the
gasket where moisture enters and corrodes the circuit board which in turn drains the key battery faster than usual. To
eliminate this concern, the thickness of the case wall on the gasket mounting surface has been increased and the
bonding strength of the components has been improved to prevent deformation.
Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE
1. Verify customer concern.
2. Verify that the remote transmitter power saving function is OFF and a CR2032 (or equivalent) battery is installed
correctly in the remote transmitter with good voltage.
NOTE: For more information on the power saving function, refer to the owner's manual.
• If the remote power saving function is ON, turn it OFF.
• If the battery is bad or installed incorrectly, replace the battery and/or install it correctly.
• If the remote power saving function is off and the battery is good and installed correctly, replace the defective
remote transmitter with a modified one according to the instructions on MGSS (IMMOBILIZER SYSTEMRELATED PARTS PROGRAMMING). NOTE: DO NOT replace other remote transmitter(s) for the vehicle if they
not experiencing an issue.
