Problem Symptoms Table
WARNING: This page is about a different car, the 2013 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- After replacing the multi-media module receiver assembly of vehicles subscribed to pay-type satellite radio broadcasts, registration of the XM radio ID is necessary (w/ SDARS System).
- If the DCM (telematics transceiver) has been replaced, perform the Activate DCM procedure using the Techstream. Refer to DCM ACTIVATION .
HINT:
