### Circuit Description

DTC C1286 is provided as an "information only" test and reflects the status of the command issued by the EBCM to illuminate the red BRAKE warning indicator.

### Conditions for Setting the DTC

When another diagnostic 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 DTC stores.

• | The ABS disables.

• | The ABS warning indicator turns on.

• | The red Brake warning indicator turns on.

### Conditions for Clearing the DTC

• | The condition responsible for setting the DTC no longer exists and the Scan Tool Clear DTCs function is used.

• | 100 drive cycles pass with no DTC(s) detected. A drive cycle consists of starting the vehicle, driving the vehicle over 16 km/h (10 mph), stopping and then turning the ignition off.

### Diagnostic Aids

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

• | 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

• | C1236

• | C1255

• | C1264

• | C1265

If any of the electrical DTCs are indicated along with DTC C1286, correct the electrical DTCs prior to addressing a DTC C1286 malfunction.
