Component Function Check
Symptom
INSPECTION FLOW
1. CONFIRM SYMPTOM BY PERFORMING OPERATION CHECK - TEMPERATURE DECREASE
2. CHECK FOR ANY SYMPTOMS
Perform a complete operational check and check for any symptoms.
3. CHECK FOR SERVICE BULLETINS
Check for any service bulletins.
4. CHECK DRIVE BELTS
Check compressor belt tension.
5.CHECK SETTING OF TEMPERATURE SETTING TRIMMER
Using CONSULT, check the setting of "TEMP SET CORRECT" on "WORK SUPPORT" of HVAC.
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 WITH ACTIVE TEST OF CONSULT
8. CHECK AIR MIX DOOR MOTOR OPERATION
Check and verify air mix door mechanism for smooth operation.
9. CHECK COOLING FAN MOTOR OPERATION
Check and verify cooling fan motor for smooth operation.
10. CHECK RECOVERY/RECYCLING EQUIPMENT BEFORE USAGE
Check recovery/recycling equipment before connecting to vehicle. Verify there is no pressure in the recovery/ recycling equipment by checking the gauges. If pressure exists, recover refrigerant from equipment lines.
11. CHECK REFRIGERANT PURITY
12. CHECK REFRIGERANT PRESSURE
Check refrigerant pressure with manifold gauge connected.
13. CHECK FOR EVAPORATOR FREEZE-UP
Start engine and run A/C. Check for evaporator freeze-up.
NOTE: Evaporator freeze up usually occurs at sustained highway speeds in hot, humid conditions with blend door at full cold and blower on low speed, after 1-3 hours of continuous driving.
14. CHECK AIR DUCTS
Check ducts for air leaks.

Road wheel tire assembly
Adjustment
BALANCING WHEELS (ADHESIVE WEIGHT TYPE)
Preparation Before Adjustment Remove inner and outer balance weights from
the road wheel. Using releasing agent, remove double-faced adhesive tape from
the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal ...
Precautions
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT
PRE-TENSIONER"
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT
PRE-TENSIONER", used along
with a front seat belt, helps to reduce the risk or severity of injury to the
driver ...
Tilt sensor
Description
The tilt sensor is installed to the steering column assembly.
The pulse signal is input to the driver seat control unit when the tilt
is operated.
The driver seat control unit counts the pulse and calculates the
tilt amount of the steering column.
