Inspection Procedure 11: Poor Reception.

DIAGNOSIS PROCEDURE

STEP 1. Check the state of the antenna.

Q. Is the antenna assembled?

Go to Step 2.

Assemble the antenna. Check that a poor reception is resolved.

STEP 2. Check to see if inspections are taking place is an area exposed to special electric fields.

Q. Are inspections taking place under special electric field conditions (underneath garage, inside a building, etc).?

Go to Step 3.

Go to Step 4.

STEP 3. Relocate and check.

Automatically receive in a good reception area that is not exposed to special electric fields.

Q. Is reception of the strongest radio frequency possible within the area?

Move the vehicle to check the trouble symptom.

Go to Step 4.

STEP 4. Tune then check.

Q. Did the sensitivity improve after tuning?

This diagnosis is complete.

Go to Step 5.

STEP 5. Check with several broadcasting stations.

note

Multipath noise and fading noise: Because the frequency of FM waves is extremely high, it is highly susceptible to effects from geological formations and buildings. These effects disrupt the broadcast signal and obstruct reception in several ways.
Multipath noise

This describes the echo that occurs when the broadcast signal is reflected by a large obstruction and enters the receiver with a slight time delay relative to the direct signal (repetitious buzzing).

Fading noise

This is a buzzing noise that occurs when the broadcast beam is disrupted by obstructing objects and the signal strength fluctuates intricately within a narrow range.

Q. Is the abnormality in reception generated only within a certain range?

Check that a poor reception is resolved.

Go to Step 6.

STEP 6. Check the connection of the antenna plug and the radio with CD player.

Q. Is the antenna plug thoroughly connected to the radio with CD player?

Go to Step 7.

Thoroughly connect the antenna plug and the radio with CD player.

STEP 7. Check by replacing the radio with CD player.

Q. Does the another radio with CD player work normally?

Either repair or replace the radio with CD player.

Either repair or replace the antenna assembly.
