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 A/C 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
