DIAGNOSIS CODE CHART


caution During diagnosis, a diagnosis code associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, confirm all systems for diagnosis code(s). If diagnosis code(s) are set, erase them all.
Follow the inspection chart that is appropriate for the diagnosis code.
Diagnosis code No.
