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) located in IPDM E/R.
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.

When cleaning the rear window, it may be easier
to clean if the high-mounted stop light is removed
first.
Be careful when removing the high-mounted
stop light to reduce the risk of damaging the
high-mounted stop light wires.
To remove the high-mounted stop light:

Manual shift mode
The transmission enters the manual shift mode by
moving the shift lever to the left side in the "D"
range. You can select the manual shift range
either by moving the shift lever up or down, or by
pulling the right-side or left-side paddle shifter (if
so equipped). To cancel the manual shift ...
