### Circuit Description

DTC C1286 is an information only DTC. DTC C1286 reflects the status of the command the EBCM/EBTCM issues to illuminate the red BRAKE warning indicator. If another DTC issues a command to illuminate the red BRAKE warning indicator, the EEPROM will store DTC C1286 as a history DTC at the conclusion of the ignition cycle.

### Diagnostic Aids

The following ABS mechanical DTCs command the red BRAKE warning indicator to illuminate. The DTCs will also cause EEPROM to store DTC C1286 during shutdown:

• | C1238

• | C1241

• | C1242

• | C1246

• | C1251

If the motors are not in their home position the following electrical DTCs will also command the red BRAKE warning indicator on:

• | C1214

• | C1216

• | C1218

• | C1255

• | C1256
