|---|---|---|---|
|
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: 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.
|
|
|
Pedal Monitor Warning: CAN hardware error.
|
This condiiton is set when CAN peripheral hardware indicates an overrun or transmission error on the primary CAN bus.
|
No immediate impact, may lead to indicating an MIA condition for the specific CAN ID listed in alert payload.
|
|
|
Pedal Monitor Slave Warning: ESP CAN node is missing.
|
|

|
|
|
Pedal Monitor Warning: ESP CAN node is missing.
|
The safety monitor sets this condition when CAN communication from ESP is considered irrational or missing.
|
ESP is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor (PM) has detected iBooster (IBST) node is MIA on Controller Area Network (CAN) for one or multiple messages.
|
IBST node is MIA on CAN for one or multiple messages.
|
iBooster may not operate as expected.
|
|
|
Pedal Monitor Warning: PM Gear Mismatch.
|
The safety monitor sets this condition when gear stalk requests intepreted by the drive inverter are considered implausible.
|
The safety monitor may automatically shift gear to neutral or potentially escalate to inhibiting torque production when detected.
|
|
|
Pedal Monitor Warning: Torque Detected in non-torque producing gear.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Deceleration Torque.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Torque Reversal.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Accumulated Torque.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Absolute Torque.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
