Controller is MIA for some time.
|
|
|
The vehicle controller detects the supply voltage from 1 or more components is outside of the expected range.
|
The vehicle controller detects the supply voltage from 1 or more components is < 7.31. Alert log signal data should provide more information on the specific condition(s) detected.

|
The pitch motor reads an unreasonably high or stall current of greater than absolute value of +/-15 amps for greater than 50 ms
|
The pitch motor will be disabled
|
|
|
Current below expected, free spinning. Seat could have pitched out from its screw.
|
Pitch motor senses low current of less than absolute value of +/- 1 amp for greater than 1 second
|

|
The pitch motor senses a failure in detecting movement
|
The pitch motor will be disabled
|
|
|
check occupancy sensor and harness, seat belt sensor and harness, damaged ECU.
|
2nd row center seat detects buckle switch is in the faulted or disconnected voltage range
|
Occupant safety is impacted
|
|
|
A large voltage drop is detected in the input power to the vehicle controller, indicating the resistance on the input power feed to the vehicle controller is higher than expected.
|
Estimated resistance on the input power feed to the vehicle controller is higher than expected.
|
The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.
|
|
|
A condition affecting switch functionality has been detected.
|
A condition is detected affecting switch functionality. Alert log signal data should provide more information on the switch affected and specific condition.
|
The switch may not function or may not function as expected.
|
|
|
Overtemp, overload, current limitation, under voltage.
|
The latch motor is running and the status output pin becomes high
|
The latch motor will be disabled
|
|
|
Latch motor encountered obstruction or end stop not handled by app.
|
The latch motor reads an unreasonably high or stall current of greater than 3.5 amps for greater than 250 ms
|
The latch motor will be disabled
|
|
|
Check for damamged motor.
|
The latch motor reads an unreasonably low current of less than 0.1 amps for greater than 250 ms
|
The latch motor will be disabled
|
|
|

|
|
Production vehicle should not have Debug Jumper in place. Remove jumper from ECU.
|
ECU Debug Jumper is set.
|
ECU Debug Jumper will disable SBC watchdog, preventing external watchdog reset protection.
