Condition
Some customers may comment that they intermittently have no
audio, turn signal click clack, or warning chime audio.
Cause
The cause of the condition may be hardware anomalies.
Correction:
1. Verify that the amplifier has a Julian date of 23327 and later. To read the Julian date, see
the image below. If the Julian date before 23327 and earlier, replace the amplifier.
Note: If there is a stock of amplifiers with the Julian date before 23327, please ship
the parts back to CCA.
2. Inspect the current radio software version. Navigate to Settings -> About -> Build
Number -> Information “i” to view and verify the software version.
If the build number is less than Y172 for IOK radios, or V171 for IOS, IOT or IOU
radios, update the A11 radio to the latest software.
Caution: Before downloading the update files, be sure the computer is
connected to the internet through a network cable (hardwired). DO NOT
DOWNLOAD or install the files wirelessly. If there is an interruption during
programming, programming failure or control module damage may occur.
Retest and see if the concern is still present. (IOK radios only) If the concern is still
present this may be due to a software anomaly in the radio. Do not replace the radio
for this condition
Engineering is aware of the issue and investigating.
