Cruise Control System (Diagnostics): Other Subaru Outback BR

PROCEDURE

CAUTIONWhen performing diagnosis, observe the legal speed limit on the road. The cancel code will 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.

CAUTION

Airbag system wiring harness is routed near the cruise control command switch.

CAUTIONDo 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.

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.
