Wireless Communication Interface Antenna Malfunction (UHP)
Diagnostic Instructions
Circuit/System Description
The wireless communication interface antenna is a small fixed
antenna connected directly to the mobile telephone control module
and is used to send and receive signals from a wireless
communication interface enabled cellular telephone. The antenna
utilizes no cabling and is not external to the vehicle.
In order to use hands-free calling, the cellular telephone must
be paired to the vehicle. Up to five devices can be paired to the
vehicle at one time, but only one can be connected at any given
time. To pair a phone, the customer must know how to operate the
wireless communication interface functionality of their phone. The
pairing process must only be done one time for each phone, unless
that phone's information is deleted. For safety reasons, the
pairing process is disabled while the vehicle is moving.
Diagnostic Aids
| • |
The purpose of this diagnostic
is to verify the ability of the K82 mobile telephone control module
to pair to a wireless communication interface device. |
| • |
Before performing this test,
verify compatibility of the cellular telephone the customer is
attempting to use with the vehicle. Based on the cellular phone's
service provider and the manufacturer's implementation of Bluetooth
®, not all phones support all available wireless communication
interface functionality. |
| • |
If the vehicle passes the
following tests and a compatible device is being used, the concern
may be due to a device malfunction or an incomplete/improper
pairing attempt. |
| • |
A wireless communication
interface test tool or equivalent can also be used to verify the
ability of the customers cellular phones to pair with another
device. |

Circuit/System Verification
| 1. |
Verify DTC B2485 is not
set. |
| 2. |
Set up a wireless
communication interface test tool or equivalent. |
| 3. |
Follow the instructions
provided in the Vehicle Owners Manual for pairing a device. Verify
successful pairing with the test tool. |
| ⇒ |
If pairing is not successful, repeat the pairing
process. If pairing is still not successful, replace the K82 mobile
telephone control module. |
| 4. |
Refer to Diagnostic
Aids. |
