RDAR = Remote Digital Audio Receiver (Satellite radio tuner)

This TJ replaces TJ25950 and previous versions of TJ26188.

For repair order dates on or after February 4th, 2013, RDAR units are removed from the prior approval process. It is no longer necessary to use the Prior Approval application on VRC(2), however all warranty claims for RDAR replacement will be reviewed.

There is no need to replace the RDAR due to:

1. No function, Locked condition:
- Not possible to select SAT1 or SAT2 as an audio source.
- SAT1 or SAT2 may be visible, but there is no reaction from the system when selecting them.
- It will not be possible to access any Sirius menu items.
- This Locked condition in combination with other factors may result in a higher than normal standby-current consumption. DTC 0008 or U300098 (overheated) may be set.

Analysis of units returned to TMA shows that almost all units could have been recovered.

Software is now available to prevent this condition from reoccuring.

1A. To recover P1 and XC90 units:
- Remove the fuse or the power/ground connector to the RDAR and re-install after 10 seconds.
- Perform an RDAR Upgrade with VIDA. This will recover the unit and prevent the condition from reoccuring.
- It will now be possible to select satellite radio as an audio source. An Updating Channel List message will be displayed.
- If there is no active subscription, the procedure is complete. Channel 184 may become visible or the Updating Channel List message may remain as long as there is no active subscription. Both conditions are normal.
- If there is an active subscription, the unit should be refreshed by entering the 12 digit Sirius ID and clicking on Send Activation Request at https://care.siriusxm.com/retailrefresh_view.action while the vehicle is running, audio system on & a clear view of the sky. The web page will
display the message "Activation Request Sent". After a few minutes, the vehicle will receive the signal, the channel list will be updated and audio will be available on the channels included in the subscription. If the web page displays the message "Please enter a valid ESN" even though the correct ESN was entered, there is no active subscription.

Note:
In addition to the 12 digit Sirius ID being on the unit itself, it can also be found in the Warranty Inquiry screen for some vehicles where the original unit has not been replaced previously.

1B. To recover P3 units:
- It is normally not possible to recover the unit using VIDA on P3 cars.
- Lift the luggage compartment floor, unplug the power/ground connector to the RDAR and plug it back in after 10 seconds.
- Copy the 12 digit Sirius ID number printed on the label.
- Have the vehicle running, audio system on & a clear view of the sky.
- Go to https://care.siriusxm.com/retailrefresh_view.action , enter the ESN and choose "Send Activation Request".

The web page will display the message "Activation Request Sent". After a few minutes, the vehicle will receive the signal and SAT1 and SAT2 will be selectable. It will be possible to tune to channel 184.
There may or may not be audio on channel 184- this is dependant on the hardware variant and is normal.
Any abnormal current consumption issue caused by the RDAR will be solved.
If the web page displays the message "Please enter a valid ESN" even though the correct ESN was entered, this method will not work for the particular ESN; proceed to 1C.
Once the unit has been recovered, perform an RDAR upgrade which will prevent the condition from reoccuring.
If they like, the customer can call Sirius and purchase a valid subscription as usual.

1C. Only necessary if 1B does not recover the unit:
- Call the Sirius/XM Dealer Support (800) 852-9696, Press 2

To minimize confusion, use these exact instructions when speaking to the agent:
- State that you would like to "add a receiver to an engineering account and send an Engineering Restore signal".
- You will be asked for the 12 digit Sirius ID number.
- You will be asked for the account number: 112762201932
- You may be asked for an address: 1 Volvo Drive, Rockleigh NJ 07647
- You may be asked to tune to channel 184. This will not be possible due to the current state of the unit; ask the agent to send the signal anyway.
- The agent should now be able to add the receiver to the account and send the Engineering Restore signal.

If the Sirius agent is unfamiliar with this procedure you may have to assist them.
The exact steps the agent needs to follow are:
1. Click on the blue plus symbol (+) next to "Overrides".
2. Type in "ENG" (in capital letters).
3. Click on "Override Promo Code".
4. Click "All Audio Packages".
5. Scroll down to "Engineering Restore" (It must be exactly "Engineering Restore", nothing else).
6. Choose "Next"

After a few minutes, the vehicle will receive the signal and SAT1 and SAT2 will be selectable.

An Updating Channel List message may be displayed or the display may be blank.

Once the unit has been recovered, perform an RDAR upgrade which will prevent the condition from reoccuring. The fault is now repaired; any abnormal current consumption issue caused by the RDAR will be solved.

If they like, the customer can call Sirius and purchase a valid subscription as usual.

2. Specific channels are not available:
This can be caused by the Sirius channel lock settings in the vehicles menu as described in the owners manual.

3. A total vehicle stand-by current draw of approximately 60 mA which drops to under 25mA after a key cycle. This draw is triggered when the power feed to the RDAR module is interrupted for a short period of time (a few seconds) and then reconnected. This often occurs during the fault tracing process, for example when the battery cable is temporarily disconnected to insert an ammeter, when a fuse is pulled and reinstalled, when the module is unplugged and plugged in again, etc... The draw disappears after a key cycle.

The procedure for checking Stand-By current is found in VIDA:

- Information->Fault Tracing->General Diagnostics and Tests->311 Battery
- A portion of the procedure is attached.

4. An RDAR may need to be replaced:

- If the unit can not be brought online according to the above and after review by Prior Approval Department.
- For an internal DTC that can not be erased.

For other confirmed functional issues, as agreed with the Prior Approval Department. Refer also to TJ 25130.

This information is also published in SMB 39-001 and PB 39-001.

5. Confirm that the vehicle is not affected by other known stand-by current issues:
- C70: Battery drain due to convertible roof module (CRM), see TJ 24318
- P3: Too high quiescent current may drain the battery, see TJ 23515
