Minimum Signal

Electric Thermostat Output Drive - Short To Ground

P1614 - Electric thermostat output drive signal fault.: Last occurrence - minimum signal

Possible causes:
1. Engine Compartment Fusebox - Fuse 1.
2. Short circuit C0606/31 (NW) - ground.
3. Connectors C0606, C0422, C0570.
4. Harness integrity.
5. Thermostat heater element short circuit to ground.
6. Engine coolant temperature sensor.
7. Radiator outlet temperature sensor.

1. Engine Compartment Fusebox - Fuse 1.
POWER_DISTRIBUTION
- Check for fuse not correctly inserted, fuse blown, fuse connections loose, damaged or corroded.
- Certain diagnostics may also perform further checks to try and narrow down the fault. Eg Check if other circuits fed by the same fuse are also experiencing problems

2. Short circuit C0606/31 (NW) - ground.
SHORT_CIRCUIT
Check resistance < 5.0 Ohms.

3. Connectors C0606, C0422, C0570.
CONNECTOR
Check for connector not correctly latched, backed out pins, damaged pins, corroded pins

4. Harness integrity.
CIRCUIT_INTEGRITY
Check for open circuit, short circuit to ground, supply or other circuit, damaged or unlatched connector, intermediate connectors or headers

5. Thermostat heater element short circuit to ground.
