Trouble Diagnosis Procedure INFOID:0000000004306695
INTERVIEW WITH CUSTOMER Interview with the customer is important to detect t he root cause of CAN communication system errors and to
understand vehicle condition and symptoms for proper trouble diagnosis.
Points in interview
• What: Parts name, system name
• When: Date, Frequency
• Where: Road condition, Place
• In what condition: Driving condition/environment
• Result: Symptom
NOTE:
• Check normal units as well as error symptoms.
- Example: Circuit between ECM and the combination meter is judged normal if the customer indicates tachometer functions normally.
• When a CAN communication system error is present, mult iple control units may malfunction or go into fail-
safe mode.
