Alerts

DIF_torque is not received for longer than 100 milliseconds or DIF_torque is received with incorrect data length for longer than 100 milliseconds.

The Integrated Dynamic Brake (IDB) may not generate brake torque requested by DI_brakeTorqueCommandFull and instead generate brake torque requested by DI_brakeTorqueCommand. There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

RCU_actuation is received with incorrectly incrementing counter for longer than 200 milliseconds.

There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

RCU_actuation is received with incorrect CRC for longer than 200 milliseconds.

There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

RCU_actuation is not received for longer than 200 milliseconds or RCU_actuation is received with incorrect data length for longer than 200 milliseconds.

There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

RCU_status is received with incorrect CRC for longer than 100 milliseconds.

There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

RCU_status is not received for longer than 100 milliseconds or RCU_status is received with incorrect message length for longer than 100 milliseconds.

There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

The IDB detects a condition that precludes CDP function. This alert may be accompanied by causal hardware alerts (MCU, ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (IMU measurement, CDP interface signals).

The IDB may not generate brake pressure in response to a request to shift to park while the vehicle is in motion.

DI_systemStatus is not received for longer than 100 milliseconds or DI_systemStatus is received with incorrect data length for longer than 100 milliseconds.

There may be an issue with the transmitting Electronic Control Unit (ECU) or CAN bus.

The IDB detects a condition that precludes SCM function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (Intertial Measurement Unit [IMU] measurement, SCM interface signals).

The IDB may not automatically bring the vehicle to a stop in case a collision is detected by the Restraint Control Module (RCM).

BDW is requested within less than 10 seconds since the previous BDW application or the EPBL_brakeDiscWipeRequest CAN signal is received as EPB_BRAKEDISCWIPE_REQUEST_SNA for longer than 1 second.

The Integrated Dynamic Brake (IDB) may not automatically wipe the brake discs in wet or cold conditions.

The IDB detects a condition that precludes hydraulic fade compensation function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (Intertial Measurement Unit [IMU] measurement).

The IDB may not increase brake torque to mitigate brake fade. Heavy braking should be avoided. Increased braking effort may be necessary to achieve desired deceleration when brake temperatures are high. The vehicle should be driven with extreme caution.

The IDB detects a condition that precludes panic brake assist function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (Intertial Measurement Unit [IMU] measurement).

The IDB may not increase brake torque above the current request in response to fast brake pedal inputs. The brake pedal must be pressed firmly and continuously to stop during emergency braking. The vehicle should be driven with extreme caution.

The IDB detects a condition that precludes standstill skid detection function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, wheel speed sensor) or signal alerts (Intertial Measurement Unit [IMU] measurement).

The IDB may not be unable to monitor for vehicle motion while all four wheels are stationary. Vehicle hold may not automatically release if the vehicle skids.

The IDB has determined the brake torque request DI_brakeTorqueCommand to be invalid or has an internal issue that prevents it from generating brake torque in response to DI_brakeTorqueCommand. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (Intertial Measurement Unit [IMU] measurement, External Brake Request [EBR] interface signals).

The IDB may not respond to brake torque requested in DI_brakeTorqueCommand.

The IDB detects a condition that precludes VDC function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (VDC interface signals).

The IDB may not respond to DI commands to build brake torque to control vehicle dynamics or wheel spin. The vehicle should be driven with extreme caution.

The IDB detects a condition that precludes EBD function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, wheel speed sensor).

The IDB may not dynamically adjust brake distribution. The vehicle should be driven with extreme caution.

The IDB detects a condition that precludes ABS function. This alert may be accompanied by causal hardware alerts (MicroController Unit [MCU], ASIC, solenoid valve, pump, wheel speed sensor, hydraulics) or signal alerts (Intertial Measurement Unit [IMU] measurement).

The IDB may not modulate brake torque to mitigate wheel lock. The vehicle should be driven with extreme caution.

TThe IDB receives a valid CDP request via the EPBL_cdpRequest Controller Area Network (CAN) signal.

The IDB is generating brake pressure in response to a CDP request.
