Inspections Before Trouble DiagnosisBCS00102
A/T FLUID CHECK
Fluid Leakage and Fluid Level Check
Inspect for A/T fluid leakage and check the A/T fluid level. Refer to AT- 1 4 , "Checking A/T Fluid" .
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF and oil.
2. Drive vehicle for approximately 10 minutes or until ATF and
engine oil reach operating temperature.
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.

AIR BREATHER HOSE

REMOVAL AND INSTALLATION (QR20DE ENGINE MODELS)
During removal and installation of air breather hose (air duct side) be careful of the following.

Secure a mark (A) when installing air breather hose (air duct
side) to air duct so as to see the mark.

Install air breather hose (air duct side) to oil catch tank with a
mark (B) facing up. Insert air breather hose into oil catch tank
until it reaches the point where the winding radius stops.
CAUTION:
When installing an air breather hose (air duct side), be careful
not to be crushed or blocked by folding or bending the hose.

AUDIO (WITH INTEGRATED DISPLAY SYSTEM)

Symptom ChartBKS0020Q

The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.

CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be
incorrectly mastered by the customer on a computer.

Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact
Disc Standard and may not play.

Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV- 5 8 , "
Unable to Operate System with A/C
and AV Switch" .
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.

Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.

Multi-path noise: This noise results from a time difference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.
Symptom Possible malfunction location
Audio system does not work properly.
