Diagnostic ProcedureEBS01145
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect the EVAP purge hose connected to the EVAP canister.
3. Turn ignition switch ON, and select “PURG VOL CONT/V” in
“ACTIVE TEST” mode with CONSULT-II.
4. Start engine and let it idle.
5. Change the valve opening percentage with touching “Qu” or
“Qd” on CONSULT-II screen, and check for vacuum existence at
the EVAP purge hose under the following conditions.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect the EVAP purge hose connected to the EVAP canis-
ter.
3. Start engine and let it idle for at least 80 seconds.
4. Check for vacuum existence at the EVAP purge hose under the
following conditions.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK EVAP CANISTER
Refer to EC-965, "
Component Inspection" .
OK or NG
OK >>INSPECTION END
NG >> Replace EVAP canister.

SYSTEM DESCRIPTION
Auto amp. controls compressor operation by ambient temperature, intake air temperature (with diesel engine)
and signal from ECM.
Low Temperature Protection Control (With Gasoline Engine)
Auto amp. will turn compressor ON or OFF as determined by a sig-
nal detected by ambient sensor.
When ambient temperatures are higher than −2°C (28°F), compres-
sor turns ON. Compressor turns OFF when ambient temperatures
are lower than −5°C (23°F).
Evaporator Freeze Protection Control (With Diesel Engine)
Auto amp. will turn compressor ON or OFF as determined by a sig-
nal detected by intake sensor.
When intake air temperatures are higher than 4°C (39°F), compres-
sor turns ON. Compressor turns OFF when intake temperatures are
lower than 2.5°C (37°F).
DIAGNOSTIC PROCEDURE FOR MAGNET CLUTCH
SYMPTOM: Magnet clutch does not engage when A/C switch is ON.

Intake Sensor CircuitEJS004L6
COMPONENT DESCRIPTION
Intake Sensor
The intake sensor is located on the heater & cooling unit. It converts
temperature of air after it passes through the evaporator into a resis-
tance value which is then input to the auto amp.
DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR
SYMPTOM: Intake sensor circuit is open or shorted.
LED of A/C switch does not illuminate as a result of performing self-
diagnosis STEP-2.
1. CHECK VOLTAGE BETWEEN INTAKE SENSOR AND GROUND
1. Disconnect intake sensor connector.
2. Turn ignition switch ON.
3. Check voltage between intake sensor harness connector M68 (Gasoline engine) or M69 (Diesel engine)
terminal 1 (BR/Y) and ground.
OK or NG
OK >> GO TO 2.
NG >> GO TO 4.
