Inspection Procedure
POWER ANTENNA RELAY INSPECTION PROCEDURE1. Check the antenna mast for damage.
^ If damaged, repair and retest.
^ If no damage is found, proceed to step 2.
2. Inspect the power antenna relay connector (pin-4 arid 9) for corrosion and/or bent or pushed out terminals.
^ If the terminals are damaged, repair as necessary and retest.
^ If the terminals are not damaged, proceed to step 3.
3. Disconnect the power antenna relay connector.
4. Connect a jumper wire between the terminals of the female connector (pin-9).
5. Observe the antenna operation.
Terminals to be Power Antenna Operation
Short Circuited
B-G, F-H Antenna should raise
B-H, C-F Antenna should lower
^ If the power antenna operates smoothly, proceed to step 7.
^ If the antenna does not operate smoothly, proceed to step 6.
6. Inspect the following and repair as necessary. If no problem(s) is found, replace the power antenna relay.
^ Check the antenna fuse.
^ Check the wiring harness between the antenna fuse and the power antenna relay (terminal B in the 9-pin connector) for an open circuit or short to ground.
^ Check the wiring harness between the body ground and the power antenna relay (terminal F in the 9-pin connector) for an open circuit.
7. Confirm that the power antenna relay connector is disconnected.
8. Turn the ignition ON.
9. Turn the audio unit ON.
10. Verify that voltage +B is applied to terminal A in the power antenna relay connector (female side, 9-pin connector).
^ If applied, replace the power antenna relay.
^ If no voltage is applied, proceed to step 11.
11. Check for an open circuit or short to ground in the wiring harness between the audio unit (terminal D in the 12-pin connector) and the power antenna relay (terminal A of the 9-pin connector)
^ If an open circuit or short to ground exists, repair and retest the antenna operation.
^ If no problems are found, replace the audio unit.
