DTC A086 EBCM Turned On The Red Brake Warning Lamp:

Circuit Description:
This DTC is provided as an informational only DTC, and reflects the status of the command issued by the EBCM to illuminate the "BRAKE" indicator. If another DTC issues a command to illuminate the "BRAKE" indicator, DTC AO86 will be stored in EEPROM as a history of the conclusion of the ignition cycle.

Test Description:
Number(s) below refer to circled number(s) on the diagnostic chart.
1. This step serves to identify if a DTC other than DTC AO86 commanded the "BRAKE" indicator on.

Diagnostic Aids:
Any ABS mechanical DTC that issues a command to illuminate the "BRAKE" indicator will also result in DTC AO86 being stored in EEPROM during shut down.

These DTCs are: AO42, AO46 and AO51. If the motors are not in their home position, certain electrical DTCs will also command the "BRAKE" indicator on. These DTCs are: AO14, AO16, AO18, AO55, AO64, AO65 and AO66.

If any of these DTCs are indicated along with DTC AO86, they must be corrected prior to addressing a DTC AO86 malfunction.
