* The values are subject to change according to vehicle model or condition

Is oil pressure value within specification?
YES : --> Repair AUTO TRANSAXLE (Clutch or Brake) as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

NO : --> Replace AUTO TRANSAXLE (BODY CONTROL VALVE faulty) as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
