DTC 86

Fig. 388 Code 86: EBCM Has Illuminated Red "Brake" Warning Lamp:

DTC 86 EBCM Turned "ON" The Red "Brake" Warning Lamp:

Circuit Description:
This DTC is provided as an "information only" test and reflects the status of the command issued by the ABS EBCM to illuminate the red "BRAKE" warning lamp. If another diagnostic DTC issues a command to illuminate the red "BRAKE" warning lamp, DTC 86 will be stored in EEPROM as a history DTC at the conclusion of the ignition cycle.

DTC Chart 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 86 commanded the red "BRAKE" warning lamp "ON."

Diagnostic Aids:
Any ABS mechanical DTC that issues a command to illuminate the red "BRAKE" warning lamp will also result in DTC 86 being stored in EEPROM during shut down. These DTC's are: 38, 41, 42, 45, 46, 47, 48 and 51. If the motors are not in their home position, certain electrical DTC's will also command the red "BRAKE" warning lamp "ON." These DTC's are: 14, 18, 55, 56, 57, 58, 61, 62, 63, 64, 65, 66, 67, 68, 71 and 72.

If any of these DTC's are indicated along with DTC 86, they must be corrected prior to addressing a DTC 86 malfunction.
