Cell Phone - Various Bluetooth(R) Cell Phone Issues

No: LTB00325 (ISSUE 2)

ISSUE '2' CHANGES ARE HIGHLIGHTED IN GRAY AND SHOWN BY ASTERISKS

SECTION: 415

Bluetooth(R) Telephone Issues

AFFECTED VEHICLE RANGE:

CONDITION SUMMARY:

NOTE:

Vehicles eligible for UPS2910/ Q110 (LR4, Range Rover Sport) or UP53710/ Q111 (Range Rover) should be updated as part of the relevant

UPS in lieu of this Technical Bulletin.

Situation:

Vehicles equipped with the inbuilt Bluetooth?telephone system *(LR4 vehicles; only if fitted with Navigation system)* may benefit from the

following improvements:

^ Improved Bluetooth(R) pairing when handset is initially paired to vehicle.

^ Improved Bluetooth(R) auto-connection when ignition is switched ON

^ Maintaining Bluetooth(R) connection between handset and vehicle or reduced likelihood of Bluetooth(R) connection being lost during

journey.

^ Improved iPhone(R) compatibility. Better audio handling when transferring phone audio between handset and vehicle. For example, when an

incoming call is answered, the call would sometimes be transferred to the handset and the user would be unaware. This appears the call is

dropped.

Action:

In the event of a customer concern of any of the above, refer to the Repair Procedure outlined below to perform the Cellular Telephone control

module Service Update. In addition, a copy of Bluetooth(R) Phone Recommendations (attached) should be presented to vehicle owners upon

completion of the software update/

PARTS:

No parts necessary

TOOLS:

IDS with latest IDS-DVD and Calibration File; first available on IDS-DVD123_V7.05 Calibration File 52

Land Rover-Approved Midtronics Vehicle Power Supply

Refer to Workshop Manual for any required special tools

WARRANTY:

NOTE:

Check vehicle in DDW for Update Prior to Sale eligibility (UP52910 / Q110 [LR4, Range Rover Sport] or UP53710 / Q111 [Range Rover])

prior to performing the Repair Procedure outlined below. If eligible, perform the necessary repairs in the relevant UPS in lieu of this Technical

Bulletin. Check DDW Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken

as guidance only. Always refer to DDW to obtain the latest repair time.

DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.

REPAIR PROCEDURE

UPDATE THE CELLULAR TELEPHONE CONTROL MODULE SOFTWARE

*1. LR4 vehicles only: verify vehicle is fitted with Navigation system. (Figure 1)

^ If fitted with Navigation system, continue to step 2.

^ If not fitted with Navigation system, Bluetooth(R) phone module update cannot be performed.*

CAUTION:

Ensure all ignition 'ON' / ignition 'OFF' requests are carried out; failure to perform these steps may cause damage to control modules in the

vehicle.

CAUTION:

A Land Rover-approved Midtronics Vehicle Power Supply must be connected to the vehicle battery during IDS diagnosis / module

programming.

1. Connect the Land Rover-approved Midtronics Vehicle Power Supply to the vehicle battery.

2. Turn ignition ON (engine not running).

NOTE:

IDS must be loaded with IDS-DVD123_V7.05 or later and Calibration File 52 or later.

3. Connect the IDS to the vehicle and begin a new Symptom Driven Diagnostics (SDD) session.

4. Follow the on-screen prompts, allowing SDD to read the VIN and identify the vehicle.

5. From the Session Type selection screen, choose 'Diagnosis'.

6. Select the Selected Symptoms tab, and then select:

^ Electrical > Information and entertainment system > Telephone system

7. Select 'continue'.

8. Select the 'Recommendations' tab.

9. From the Recommendations tab, select Run to perform the 'Cellular telephone module Service Update'.

^ Follow all on-screen instructions to complete this task.

10. Exit the current session.

11. Disconnect the IDS and the Midtronics Vehicle Power Supply from the vehicle.

Please use the list below when investigating Bluetooth(R) phone pairing issues.

NOTE:

certain issues may be caused by the customer handset.

1. Ensure customer handset is listed on the Bluetooth(R) compatibility web page.

2. If poor Bluetooth?performance is still experienced (connection lost between handset and vehicle), it may be advantageous to disable WiFi, if

fitted, on the handset during Bluetooth(R) connection to the vehicle.

NOTE:

Retailer facilities are typically noisy Bluetooth?areas due to personnel having their own handsets with Bluetooth?on and within range of the

vehicle.

3. The initial Bluetooth?pairing process is best carried out in a Bluetooth(R) quiet zone where there no other active Bluetooth?devices within range.

If the handset or vehicle detects several devices during pairing it is more difficult to guarantee a reliable pairing of devices.

4. The pairing process is conducted from the handset with the vehicle ignition ON and in range of the vehicle. The pairing passcode is 2121.

5. The system will allow up to five handsets to be paired to the vehicle. Only one handset can be connected at any one time. If a sixth handset is

paired, the oldest handset will be automatically removed and will then no longer auto-connect. This handset will have to be paired again if

required.

6. If phone audio is poor or Bluetooth(R) is still unreliable, try one or more of the following:

a. End call and redial the number again. This could eliminate a network connection issue.

b. Check network connection and signal strength. No network is displayed if no phone network signal is present. Try phone call again when

signal returns.

c. Shut down then power up handset again. This will reset the handset and correct any potential Bluetooth(R) link corruption between the

handset and vehicle.

d. Switch the vehicle OFF, lock the vehicle for at least 10 seconds, and then unlock. Retry call from vehicle. It is possible during engine crank

the vehicle system voltage dropped low and caused an infotainment corruption at start up. This procedure will reset the infotainment system.

e. Delete Land Rover device from handset and pair again.

f. Delete any unused Bluetooth(R) devices stored in the handset.

g. Encourage the driver to project their voice towards the microphone during a call, speaking loudly and clearly without shouting.

h. Recommend that sunroof and windows are closed during a call. Wind noise will reduce clarity of the call. Also, be aware that road noise

increases at higher speeds.

i. Ensure the driver has set the call volume to a comfortable level.
