If the calculated output torque is lower than a limit of tolerance, it sets P1830 and lets a warning lamp turn on.

•
Comparing a target torque to a real torque | 1. Poor connection 2. Internal error in the coupling 3. 4WD ECU |
Enable conditions |

Engine ON | |
Threshold value |
•
The torque of coupling is too high rather than a target torque. | |
