Self-Diagnostic Function

Self-diagnostic Function-Code Cycle Break:

The self-diagnostic function integrated within the cruise control unit diagnoses the condition of the cruise control system.

Condition/operation codes, stored in the cruise control memory, are indicated by the cruise indicator in the instrument cluster. (Refer to condition code numbers). Stored codes are deleted when the ignition switch is turned to OFF. In addition, the memory will hold only a single code at any time. If multiple malfunctions are present, the first one displayed will have to be corrected before the next code can be displayed.
