|
|
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.
|
No
|
|
|
Pedal Monitor Warning: Switch-off Path Test Failed.
|
This condition is set when the power electronics and DI-PM switch-off path test fails, most likely due to damaged inverter hardware.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
No
|
|
|
Pedal Monitor Warning: Peripheral Register Configuration Error.
