Pedal Monitor Warning: DIS CAN node is missing.
|
The safety monitor sets this condition when CAN communication from DIS is considered irrational or missing.
|
DIS is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: Master/Slave Torque Sign is Inconsistent.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will disable innhibit torque production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Pre-watchdog expired.
|
This condition is set the watchdog GPIO pin is set, indicating an immediate watchdog reset is imminent. This alert is intended to collect diagnostic information only.
|
This alert provides an imminent warning of a likely watchdog reset event.
|
|
|
Pedal Monitor Warning: Peripheral Register Configuration Error.
|
This condition is set when a the GPIO register of the ECU reports a configuration error, intended to be a diagnostic alert only.
|
No immediate impact.

Pedal Monitor Warning: Inconsistent AEB state.
|
The safety monitor sets this condition when sensor or other ECU inputs into AEB are deemed implausible.
|
The safety monitor will disable automatic emergency braking (AEB) for the remainder of the drive cycle.
|
|
|
The pedal monitor (PM) electronic control unit (ECU) detects that the Etherloop Generalized Gateway Right (EGGRIGHT3) controller area network (CAN) node is missing (MIA).
|
The PM ECU is not receiving the expected CAN communication from the EGGRIGHT3, and considers it irrational or MIA.
|
The PM ECU is unable to monitor the state of the EGGRIGHT3.
|
|
|
Pedal Monitor Warning: DI Heartbeat is missing.
|
The safety monitor sets this condition when DI Heartbeat communication is too fast or too slow.
|
The safety monitor will initiate a unit limp condition for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Reset for unintended reason.
|
This condition is set when this ECU powers on and detects an abnormal reset condition from the previous power cycle (for example, from a watchdog timeout).
|
No immediate impact.
|
|
|
Pedal Monitor Warning: Brake Pedal Error.
|
This condition sets when BLS NO and NC circuits are considered implausible.
|
Diagnostic logging only.
|
|
|
Pedal Monitor Warning: Cruise remained on when commanded off.
|
The safety monitor sets this condition when cruise control operation intepreted by the drive inverter is considered implausible.
|
The safety monitor may automatically cancel cruise control operation or potentially escalate to inhibiting torque production when detected.
|
|
|
Pedal Monitor Warning: DIR CAN node MIA.
|
PM is not receiving required feedback CAN messages from DIR
|
Unable to monitor DIR state
|
|
|
Pedal Monitor Warning: DIF CAN node MIA.
|
PM is not receiving required feedback CAN messages from DIF
|
Unable to monitor DIF state
|
|
|
Pedal Monitor Warning: Crawl and Hill Descent modules inhibited.
|
The safety monitor sets this condition when torque production error is detected while Crawl or Hill Descent modules are active.
|
The safety monitor will disable crawl and hill descent modules until the vehicle has come to a stop and blended out torque (park/neutral, vehicle hold, or drive cycle).
|
|
|
Pedal Monitor Warning: Parking Brake CAN node is missing.
|
The safety monitor sets this condition when CAN communication from Parking Brake CAN node is considered irrational or missing.
|
Parking Brake CAN node is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: Excessive torque rate delta.
|
The safety monitor sets this condition when the torque changes too quickly on the brake pedal in an offroad speed control mode.
|
The safety monitor will disable offroad speed control modes for the remainder of the drive cycle.
|
|
|
One or more of the messages the Propulsion Monitor (PM) Electronic Control Unit (ECU) receives periodically from the Decoupled Brake Booster (BB) ECU is not received, indicating the BB ECU may be unavailable (MIA).
|
One or more of the expected messages from the BB ECU is not received.
|
Regenerative-friction brake torque blending functionality may be limited or unavailable.
|
|
|
Pedal Monitor Warning: Gear Shifter CAN node is missing.
|
The safety monitor sets this condition when CAN communication from Gear Shifter CAN node is considered irrational or missing.
|
Gear Shifter CAN node is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: Accelerator Pedal Error.
|
The safety monitor sets this condition when accelerator pedal sensor measurements are irrational or out of bounds.
|
The safety monitor will initiate a limp condition for the remainder of the drive cycle.
