== P2556 - Engine Coolant Level Sensor/Switch: Electrical Malfunction ==

==== Possible Symptoms ====

* MIL On
* Cooling system malfunctioning

==== Possible Causes ====

* Faulty Engine Coolant Level Sensor (G32)
* Faulty Engine Temperature Control Actuator (N493)
* Wiring or power/ground issues to those components

==== Possible Solutions ====

* Check Engine Coolant Level Sensor (G32), Engine Temperature Control Actuator (N493) in addition to the related wiring per the [[Official Factory Repair Information |repair manual]].

==== Special Notes ====

* At face value you would initially believe this DTC is for the Engine Coolant Level Sensor however in most cases that sensor is wired to the 17-Instrument Cluster or the 09-Central Electronics. The Coolant Level Sensor is not usually wired directly to the 01-Engine control module. In those cases the thermostat (N493) and the wiring to it should be checked as per post #8 in this thread: https://forums.ross-tech.com/index.php?threads/28967/
** The example vehicle would use this generation 09-Cent. Elect. module [[MLB based Cent. Elect. (J519) BCM1]] and measuring block group 028.1 can be used to check the Coolant Level (G32) status.
