Component Location
General Description

The EPB ECU checks the battery voltage and alternator output voltage to determine, as a safety issue,

whether this system can operate normally or not.

The normal battery voltage range is essential for controlling this system as intended

DTC Description

When hardwire ignition signal and CAN ignition signal are different, EPB ECU sets DTC
