Introduction-How to Troubleshoot the Vehicle
Symptoms chart
A symptoms chart is used to show possible causes (e.g. circuits or parts) of each symptom (as
shown in the table below). If the malfunction persists when a hand-held diagnostic tester indicates
normal system, you can perform trouble diagnosis and troubleshooting using the symptoms chart.
The SNs in the table represents check sequence of circuits or parts.
Tip:
If a symptom really exists when no malfunction is detected by the vehicle diagnostic system, it
indicates that the existing malfunction is beyond the detection range of the system.
