DETAILS OF TROUBLE DIAGNOSIS FLOWCHART
- OBTAIN INFORMATION ABOUT SYMPTOM Interview the customer to obtain as much information as possible about the conditions and environment under which the malfunction occurs. GO TO 2.
- CHECK SYMPTOM Check the symptom based on the information obtained from the customer. Check if any other malfunctions are present. GO TO 3.
- CONSULT SELF-DIAGNOSIS Perform "MULTI DISPLAY" "self diagnosis" by connecting CONSULT. When DTC is detected, follow the instructions below: Record DTC and Freeze Frame Data. NOTE: If "CAN COM CIRC [U1000]" is displayed, start the diagnosis from the CAN communication system. Refer to " «DIAGNOSIS PROCEDURE»(ref-516457-S37357724952012120600000) ". Is any DTC No. displayed? YES: GO TO 4. NO: GO TO 5 .
