Present Diagnostic Test Mode

Present Diagnostic Test Mode
Immediately after starting the on-board diagnostic function, present failures in the control circuit, such as disconnections or short circuits, are detected and indicated on the SST (Control Unit) as diagnostic trouble codes. If a diagnostic trouble code is indicated, refer to the following diagnostic trouble code table and inspect the appropriate system. (The SST (Control Unit) will not, however, detect a short circuit in the (W) solar radiation sensor signal wire.)
