DTC 86
CIRCUIT DIAGRAM
INSPECTION PROCEDURE
CIRCUIT DESCRIPTION:
This DTC is provided as an informational only DTC, and reflects the status of the command issued by the Electronic Brake Control Module (EBCM) to illuminate the "BRAKE" warning light. If another DTC issues a command to illuminate the " BRAKE" warning light, DTC 86 will be stored in EEPROM as a history DTC at the conclusion of the ignition cycle.
DIAGNOSTIC AIDS:
Any Antilock Brake System (ABS) mechanical DTC that issues a command to illuminate the "BRAKE" warning light will also result in DTC 86 being stored in EEPROM during shut down. These DTCs are: 42,46 and 51. If the motors are not in their home position, certain electrical DTCs will also command the "BRAKE" warning light on. These DTCs are: 14,16,18,36,55,64,65 and 66.
If any of these DTCs are indicated along with DTC 86, they must be corrected prior to addressing a DTC 86 malfunction.
