Transmitter Battery Inspection

WARNING: This page is about a different car, the 2004 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Since the battery voltage does not drop fully if the button is pushed for only 4 s or less, sufficient battery voltage cannot be determined. Always push the button for 5 seconds.
NOTE:
  • A correct measurement cannot be obtained if the battery temperature is low. Make sure the battery is at 18 °C {64 °F} or more  for at least 30 min before reinspecting if a measurement value is under the standard voltage.
  1. Remove the transmitter cover.
  2. Apply the voltmeter leads to the positions as indicated in the figure.

  3. While pressing the battery as shown in the figure, press the LOCK and UNLOCK buttons on the transmitter at the same time to start measurement of the voltage.
  4. Release the buttons after 5 s. 
  5. Verify that the minimum voltage is the standard voltage or more for 10 s  after starting measurement.
    • If the voltage is under the standard voltage, replace the battery.
