PROCEDURE
| CAUTION | When performing diagnosis, observe the legal speed limit on the road. The cancel code will be also appear when cruise control is cancelled by the driver's operation. Do not confuse them. Be sure to get an assistant to support the diagnosis while driving, and have him/her operate the select monitor. |

| NOTE |
|---|
| Do not turn the ignition switch to OFF after the cruise control is deactivated. Do not operate the cruise control command switch after the cruise control is deactivated. If the above is performed, the cancel code will be cleared. |
CAUTION
Airbag system wiring harness is routed near the cruise control command switch.
| CAUTION | Do not use the electrical test equipment on the airbag system wiring harnesses and connector circuits. Be careful not to damage the airbag system wiring harness when servicing the cruise control command switch. Airbag system wiring harness is routed near the cruise control command switch. |
GENERAL TOOL
| TOOL NAME | REMARKS |
|---|---|
| Circuit tester | Used for measuring resistance, voltage and current. |
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 is 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 | Note |
|---|---|---|---|
| 11 | Main switch | CRUISE switch of cruise control command switch is turned to OFF, and then the cruise control is released. | This code is displayed without operating the CRUISE switch. Refer to 11 . |
