Trouble Diagnosis Procedure
INTERVIEW WITH CUSTOMER
Interview with the customer is important to detect the 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
Notes for checking error symptoms: • Check normal units as well as error symptoms.
• 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, multiple control units may malfunction or go into failsafe mode.
• Indication of the combination meter is important to detect the root cause because it is the most obvious to the customer, and it performs CAN communication with many units.
INSPECTION OF VEHICLE CONDITION
Check whether the symptom is reproduced or not.
NOTE
:
Do not turn the ignition switch OFF or disconnect the battery cable while
reproducing the error. The error may
temporarily correct itself, making it difficult to determine the root cause.
CHECK OF CAN SYSTEM TYPE (HOW TO USE CAN SYSTEM TYPE SPECIFICATION CHART)
Determine CAN system type based on vehicle equipment.
NOTE
:
• This chart is used if CONSULT-III does not automatically recognize CAN system
type.
• There are two styles for CAN system type specification charts. Depending on the number of available system types, either style A or style B may be used.
CAN System Type Specification Chart (Style A) NOTE
: CAN system type is easily checked with the vehicle equipment identification information shown in the chart.
CAN System Type Specification Chart (Style B)
NOTE
: CAN system type is easily checked with the vehicle equipment identification information shown in the chart.
