LIST
Note. The cancel code is registered even when cancel is performed intentionally by the driver. Cancel codes are cleared if the ignition switch is turned to OFF. If a different cancel code is input after a cancel code (latest code) has been input, the latest code is overwritten. If the cruise indicator light is flashing, a malfunction is occurring in the system or cruise control related switch. The cancel code at this time is saved even after ignition switch OFF as a memory code of a past malfunction. To display a cancel code, use the Subaru Select Monitor to read the code after the cruise control is deactivated during a driving test.
| Cancel code | Item | Contents of diagnosis | Reference |
|---|---|---|---|
| 11 | Main Switch | Main switch of cruise control command switch is turned to OFF, and then the cruise control is released. | This code is displayed without operating the main switch. Refer to DTC 11 , Diagnostic Procedure without Diagnostic Trouble Code (DTC). |
| 12 | Stop Light & Brake Switch | Stop light switch or brake switch is turned to ON, and then the cruise control is released. | This code is displayed without depressing the brake pedal. Refer to DTC 12 , Diagnostic Procedure without Diagnostic Trouble Code (DTC). |
| 13 | Clutch Switch | Clutch switch is turned to ON, and then the cruise control is released. | This code is displayed without depressing the clutch pedal. Refer to DTC 13 , Diagnostic Procedure without Diagnostic Trouble Code (DTC). |
| 14 | Neutral Position Switch | Neutral position switch is turned to ON, and then the cruise control is released. | This code is displayed without shifting to neutral position. Refer to DTC 14 , Diagnostic Procedure without Diagnostic Trouble Code (DTC). |
