| == 18613/P2181/008577 - Performance Malfunction in Cooling System ==
| |
|
| |
| ==== Possible Causes ====
| |
|
| |
| * Faulty Coolant Sensor
| |
| * Faulty Coolant Thermostat
| |
| * Faulty Wiring, Connections
| |
|
| |
| ''Note'': This fault code sets when engine coolant temperature mapping is lower and out of expected range based on operating conditions of the engine.
| |
| * For example: Engine warms up, thermostat opens and stays open, coolant temperature drops below normal operating range. The ECM knows the coolant temperature should stay within 80.0...110.0 °C typically after warm up. Thus a drop in coolant temperature below normal operating temperature is not possible without a malfunction in cooling system.
| |
|
| |
| ==== Possible Solutions ====
| |
|
| |
| * Check G62 - Engine Coolant Temperature Sender <br>
| |
| ** Inspect wiring for G62 (Coolant Migration, damage, corrosion, etc)
| |
|
| |
| * Check (if applicable) G83 - Radiator Outlet, Coolant Temperature Sender <br>
| |
| ** Inspect wiring for G83 (Coolant Migration, damage, corrosion, etc)
| |
|
| |
| * Check Coolant Thermostat
| |
| ** Use Graph function in VCDS, Measuring Value Blocks - MVB
| |
| ** Start Engine cold, graph Coolant Temperature Sender (G62) Typically MVB Group-001
| |
| ** Hold RPM around 1,500rpm and watch coolant temp increase in Graph until thermostat opens, indicated by a slight drop in coolant temp
| |
| ** If coolant temp drops below minimum operating temperature (80°C) or never reaches operating temperature, (verified by external thermometer) suspect failed thermostat
| |
|
| |
| * Vehicles with both G62-Engine Outlet, Coolant Temperature Sensor and G83-Radiator Outlet, Coolant Temperature Sensor
| |
| ** Use Measuring Value Block group MVB-130 instead on MVB-001
| |
| ** G62 should increase in Temperature before G83 increase when engine coolant is cold
| |
| ** G83 will increase when the thermostat opens and after G62 reaches operating temperature (80°C)
| |
| ** If G62 and G83 both increase while engine warms up, suspect failed thermostat
| |
|
| |
|
| |
| ==== Special Notes ====
| |
|
| |
| * Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
| |
| ** Freeze Frame data stored at -40*C is generally an indication of a faulty ECT or wiring.
| |
| ** Freeze Frame data stored at +140*C is generally an indication of a faulty ECT or wiring.
| |
| ** Freeze Frame data stored with in the 68*C ~ 80*C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.
