VTM-4 Indicator

VTM-4 Indicator
The VTM-4 indicator comes on under certain conditions even if the 4WD system is working normally. Here are some examples:
- When you use high-powered wireless equipment such as a CB or Ham radio in the vehicle.
- When you keep spinning the rear wheels while the vehicle is stuck in sand, mud, snow, etc.
- When the battery voltage suddenly drops below 8 volts or rises above 16 volts.
After the VTM-4 indicator comes on, it stays on until you turn the ignition switch off.
