Troubleshooting:
Situation Correction
No audio output through vehicle speakers
Check SES module jumper plug
Radio does not mute after placing a call
Check connections at rear of radio for Tel On and
Tel Mute signal. Verify that connectors and pins
are properly seated.
Audio quality in vehicle may not sound very good
•
Recode ULF Control Module.
•
NOTE: Audio quality in vehicle or at person
being contacted, is dependent on the quality
and signal strength of the wireless service
provider in the area traveled.
Customer complains that the person being
contacted hears a “Buzzing” noise, at times during
their conversation or on voice mail message that
he/she has left.
Intermittently a “Buzzing” noise is noticeable to the
person being called from the vehicle. The
“Buzzing” noise is a result of the GSM signal being
feedback through the microphone, this usually
occurs if the GSM phone is located too close to
the microphone. The customer should change the
location of where the phone is placed/stored.
Driver is told that the person being contacted
complains that there is an echo/reverberation in
the audio; person can hear his/her voice back
through the phone.
Audio volume in vehicle during a call may be a bit
to loud, causing the other person to hear his/her
voice coming back through the phone.
A second call is received while in a call, and call
cannot be accepted using MFL controls.
Use handset to expect second call and place
previous called on hold. Call waiting is functional
only via the handset.
The radio audio does not come back immediately
if the “other” person hangs up first.
It takes approximately 15 seconds for the ULF
system to recognize that the call was terminated
from outside the vehicle.
If the call is terminated from outside the vehicle
first, the driver can depress the button on the
steering wheel to terminate the call from the
vehicle and un-mute the radio quicker.
Customer is not able to pair phone to system, not
able to locate ULF passkey/password reference
card.

Intermittently a popping noise is audible through
the vehicles speaker and there is no Bluetooth
TM
