SELF-DIAGNOSIS FUNCTION
10.
CHECK IN-VEHICLE SENSOR
Press
(DEF) switch for the second time. Temperature detected
by in-vehicle sensor is indicated on the display.
NOTE:
If the temperature indicated on the display greatly differs from the
actual temperature, check sensor circuit first, and then check sensor.
Is the inspection result normal?
YES
>> GO TO 11
NO
>> Go to In-vehicle Sensor Circuit. Refer to
.
11.
CHECK INTAKE SENSOR
Press
(DEF) switch for the third time. Temperature detected by
intake sensor is indicated on the display.
NOTE:
If the temperature indicated on the display greatly differs from the
actual temperature, check sensor circuit first, and then check sensor.
Is the inspection result normal?
YES
>> GO TO 12
NO
>> Go to Intake Sensor Circuit. Refer to
12.
CHECK MALFUNCTIONING SENSOR AND DOOR MOTOR
Refer to the following chart for malfunctioning code No.
(If two or more sensors and door motors malfunction, corresponding code Nos. indicates 1 second each.)
(If two door motors malfunction, corresponding code Nos. indicates 0.5 second each.)
*1: Perform self-diagnosis STEP-2 under sunshine.
When performing indoors, aim a light (more than 60W) at sunload sensor, otherwise code No. 25 will indicate
despite that sunload sensor is functioning properly.
NOTE:
Code 20 will be displayed if all sensor s and PBR(s) are OK.
