Transmitter Battery Inspection

WARNING: This page is about a different car, the 2005 Mazda 6. 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 seconds or less, it can not be properly examined to see whether it is good or bad. 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 minutes  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.

    • If the voltage is under the standard voltage, replace the battery.
