Toyota 86309-02050 Pole Sub-Assy, Roof Antenna

The vehicles covered are equipped with a mast-type antenna attached to the rear of the roof. If the antenna mast is damaged, it can be removed by turning it counterclockwise; wrapping the antenna with tape provides a good grip for hand removal. The antenna cable runs from the radio up through the passenger-side windshield pillar under the headliner and is joined with a connector at the rear of the roof. Removing all the panels and the headliner for access to the cables or replacement of the antenna mast base is a difficult job for the home mechanic and is best left to a qualified shop.

The vehicles equipped with a mast-type antenna attached to the rear of the roof may also have satellite radio antennas in later models, with both types mounted in the same location. If the antenna mast is damaged, it can be removed by turning it counterclockwise; wrapping the antenna with tape provides a better grip for hand removal. The antenna cable runs from the radio up through the passenger-side windshield pillar under the headliner, connecting at the rear of the roof. To replace the antenna base, the rear upper-quarter trim on the driver's side must be removed, followed by the rear headliner retaining fasteners, allowing the headliner to drop down enough to access the nut securing the antenna base to the roof. Installation follows the reverse order of removal.

The vehicles covered by these instructions have a wire grid-type antenna on the rear window glass. To troubleshoot radio reception issues, check the antenna wires for continuity using an ohmmeter. Wrap small pieces of aluminum foil around the ohmmeter probes and touch them to the antenna grid wires. Place one probe on an antenna terminal and move the other probe along the wire to check for continuity until a break is found. If a break is detected, repair the wire as you would a rear window defogger wire.
