Description
SYSTEM DESCRIPTION
A/C auto amp. controls A/C compressor operation by ambient temperature and signal from ECM.
Low Temperature Protection Control A/C auto amp. will turn the A/C compressor ON or OFF as determined by a signal detected by ambient sensor.
When ambient temperature is greater than 4C (39F), the A/C compressor turns ON. The A/C compressor turns OFF when ambient temperature is less than 2.5C (37F).
Component Function Check
1.FUNCTION INSPECTIONS
Diagnosis Procedure
SYMPTOM: Magnet clutch does not engage when A/C switch is ON.
1.INSPECTION IN AUTO ACTIVE TEST MODE
Perform "AUTO ACTIVE TEST".
2.CHECK POWER SUPPLY FOR A/C COMPRESSOR
3.CHECK FUSE
Check 10A fuse (No. 41).
4.CHECK CIRCUIT CONTINUITY BETWEEN A/C RELAY IN IPDM E/R AND A/C COMPRESSOR
1 - 48: Continuity should exist.
5.CHECK A/C COMPRESSOR CIRCUIT FOR SHORT
Check continuity between A/C compressor harness connector F3 terminal 1 and ground.
1 - Ground: Continuity should not exist.
6.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT
NOTE: If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010.
7.CHECK A/C AUTO AMP. INPUT SIGNAL
Using CONSULT, check "On/Off" of "COMP REQ SIG" and "FAN REQ SIG" in "DATA MONITOR" of HVAC.
A/C SWITCH ON: COMP REQ SIG On
A/C SWITCH OFF: COMP REQ SIG Off
FAN CONTROL DIAL ON: FAN REQ SIG On
FAN CONTROL DIAL OFF: FAN REQ SIG Off
8.CHECK REFRIGERANT PRESSURE SENSOR
Check refrigerant pressure sensor.
