Q: How to service the radio antenna cable on 2006 Scion xA?
A: Start the radio antenna service by unplugging the negative battery terminal cable then let the wait period reach at least 90 seconds to stop Air Bag and seat belt pretensioner activation.

You can disconnect the connectors before you remove the antenna cord sub-assembly through the removal of its 17 clamps. The installation process requires attachment of the antenna cord sub-assembly using 17 clamps followed by connector reconnection. Next, reinstall the roof side garnish inner RH, deck trim side panel assembly RH, rear seat 3 point type belt assembly RH, rear seat back hinge sub-assembly RH, deck trim cover rear, deck floor box rear, No. 1 deck board, tonneau cover assembly, rear seat back assembly RH, rear seat cushion with cover pad sub-assembly, center pillar garnish lower RH, rear door opening trim Weather Strip RH, front door opening trim Weather Strip RH, cowl side trim board RH, rear door scuff plate RH, front door scuff plate RH, instrument panel assembly lower, and instrument panel sub-assembly.
