Inspection Procedure 16

Poor Reception.

DIAGNOSIS

STEP 1. Check the state of the antenna.

Q: Is the roof antenna pole assembled?

YES: Go to Step 2.

NO: Assemble the roof antenna pole. 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? (underground garage, inside a building, etc.)?

YES: Go to Step 3.

NO: Go to Step 4.

STEP 3. Relocate and check.
Move the vehicle to a good reception area that is not exposed to special electric fields.

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

YES: Check that a poor reception is resolved.

NO: Go to Step 4.

STEP 4. Tune then check.

Q: Did the sensitivity improve after tuning?

YES: Check that a poor reception is resolved.

NO: Go to Step 5.

STEP 5. Check with several broadcasting stations.

NOTE: Multipath noise and fading noise: Because the frequency off M 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?

YES: Check that a poor reception is resolved.

NO: Go to Step 6.

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

Q: Is the antenna plug thoroughly connected to the radio and CD player?

YES: Go to Step 7.

NO: Thoroughly connect the antenna plug and the radio and CD player. Check that a poor reception is resolved.

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

Q: Are operations normal when using another radio and CD player?

YES: Replace the radio and CD player. Check that a poor reception is resolved.

NO: Either repair or replace the antenna assembly. Check that a poor reception is resolved.
