Low Coolant Indicator Is Always On
- Disconnect low coolant sensor. Using a jumper wire, connect low coolant sensor connector to ground. Place ignition switch in "RUN" position. Observe low coolant indicator.
- If low coolant indicator light is off, replace low coolant sensor. If low coolant indicator light is still on, check Yellow/Black wire for an open circuit. If wire is okay, replace low coolant module.
