Red Parking Brake Warning Indicator

When the parking brake is applied, the red parking brake warning indicator is continuously illuminated while the ignition is on and for 3 minutes after the ignition is switched off. If the system is unable to comply with an apply or release request, due to a system fault, the indicator flashes.

When the ignition is on and the indicator is not flashing, operation is controlled by a HS CAN bus signal. When the ignition is off or when the indicator is flashing, operation is controlled by a hardwired signal from the EPBCM to the IC.
