DIAGNOSTICS
There are diagnostic codes built into the TankVisionPro. These diagnostic codes
can help in the troubleshooting process.
If there is no input on pin 2 of the remote light driver, the remote lights remain off.
The following FAULTS are displayed as long as the fault exists.
Figure 8. Diagnostics - Faults
