A086
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 AO86 will be stored in EEPROM as a history DTC at 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 A086 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 A086 being stored in EEPROM during shut down. These DTCs are: A038, A041, A042, A045, A046, A047, A048 and A051. If the motors are not in their home position, certain electrical DTCs will also command the red brake warning lamp "ON." These DTCs are: A014, A018, A055, A056, A057, A0587, A061, A062, A063, A064, A065, A066, Ao67, A068, AO71 and A072.
If any of these DTCs are indicated along with DTC A086, they must be corrected prior to addressing a DTC A086 malfunction.
