A: WIRING DIAGRAM

B: INSPECTION
1. CHECK THE DVD-ROM.
Insert a region code 1 DVD-ROM, and check that the display shows images from the DVD when playing back
the media.
NOTE:
Region code 1 is a code for North American DVD-ROM discs. DVD-ROMs of different region codes will not
be played back.
Standard value: Image from DVD should be displayed.
OK: Normal
NG: If the images from the DVD is not displayed, check whether the DVD-ROM is set in the rear entertain-
ment system, whether the correct side is set, type of the DVD-ROM, the existence of any scratches, etc. If
there are no problems on the DVD-ROM, the main body is defective.
NOTE:
The rear entertainment system is not compatible with MP3 files or DVD-Audio.
2. ERROR DISPLAY AND CONTENT
Screen display Trouble contents
INCORRECT CODE When an incorrect number is entered.
DISC ERROR When it is not possible to read the disc due to scratches or
insertion upside down.
REGION CODE ERROR When the region code of the disc does not match (is a region
code other than 1)
MECHA ERROR Replace the rear entertainment system.
NO DISC The DVD switch was pressed when there was no disc inside.

noise.
•For option code, refer to “ID” section.
2. IDENTIFICATION
Identification label positions are shown in the fol-
lowing figures. For details concerning identification,
refer to the “ID” section.

1) Insert the EBJ into hub splines.
CAUTION:
•Be careful not to damage the magnetic en-
coder.
•Do not get closer the tool which charged
magnetism to magnetic encoder.
2) Draw the rear drive shaft into specified position.

5) While applying the parking brake and depress-
ing the brake pedal, tighten a new axle nut (olive
color) to the specified torque and lock it securely.
Tightening torque:
240 N·m (24.5 kgf-m, 177 ft-lb)
CAUTION:
•Install the wheel after installation of axle nut.
Failure to follow this rule may damage the
wheel bearing.
•Be sure to tighten the axle nut to specified
torque. Do not overtighten it as this may dam-
age the wheel bearing.

Map 2
Add the following value every 512 milliseconds.
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once at a constant 70 km/h (43 MPH) or higher.
5. DIAGNOSTIC METHOD
After the execution criteria are established, calculate the output fluctuation value of front oxygen (A/F) sensor
(averaged for the right and left) and output fluctuation value of rear oxygen sensor. Calculate the diagnosis
value when the front oxygen (A/F) sensor output fluctuation value is more than specified value. A/F response
properties and diagnosis values are parameters for the judgment value.
Judge as NG when the malfunction criteria below are met. Judge as OK if the criteria below are not met.
