CIRCUIT DESCRIPTION
Diagnostic Trouble Code (DTC) C1286 is provided as an "information only" test and reflects the status of the command issued by the Electronic Brake Control Module (EBCM) to illuminate the red BRAKE warning indicator.

CONDITIONS FOR SETTING THE DTC
When another diagnostic Diagnostic Trouble Code (DTC) issues a command to illuminate the red BRAKE warning indicator, DTC C1286 will be stored in memory as a history DTC at the conclusion of the ignition cycle.

ACTION TAKEN WHEN THE DTC SETS
^ A malfunction Diagnostic Trouble Code (DTC) stores.
^ The ABS disables.

^ The red Brake warning indicator turns ON.

CONDITIONS FOR CLEARING THE DTC
^ The condition responsible for setting the Diagnostic Trouble Code (DTC) no longer exists and the Scan Tool Clear DTCs function is used.
