Diagnostic Output Codes

Self-diagnosis checking is performed when there has been an automatic cancellation, without cancel switch operation. There are six diagnosis items, including the on for the normal condition.

As examples of the normal condition, code No. 16 is entered in the memory as cancel switch on signal input if the system is canceled by depressing the brake pedal, and code No. 13 or No. 14 is entered when there is an automatic cancellation because the vehicle speed drops when the vehicle is driven up a steep slope with the preset speed setting left set, etc.; when however, there is a cancellation not intentionally made by the driver, the cause might be damaged or disconnected stop light switch input wiring, a malfunction of the stop light switch on, etc., even though the same code No. 16 is displayed.

1. This method can be used for checking the diagnosis. Self-Diagnosis check connector is located under the driver's side of the instrument panel. See Fig 1 .

2. Connect a voltmeter between the ground terminal and the terminal for auto-cruise control of the diagnosis check connector. See Fig 2 . It is possible to discover which circuit is the cause of the cancellation by verifying the indication shown by the voltmeter with the display patterns shown.
3. When the diagnosis code No. 11, 12, 15 or 16 is displayed, check by referring to the check applicable number. See Fig 3 .
