DIAGNOSIS AND REPAIR WORKFLOW
Trouble Diagnosis Flow Chart
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
NOTE:
- Example: Circuit between ECM and the combination meter is judged normal if the customer indicates tachometer functions normally.
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:
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.
