DIAGNOSIS CODE CHART


Follow the inspection chart that is appropriate for the diagnosis code.
caution During diagnosis, a diagnosis code associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. After the troubleshooting has been completed, check whether a diagnosis code is set. If a diagnosis code is set, erase it.
Diagnosis code No.
