Diagnostic trouble code (DTC) information
Condition
Diagnostic trouble code (DTC) ECM-6110 is stored if the engine control module (ECM) registers a fault in the signal cable from the engine cooling fan (FC) relay.
NOTE:
The electric cooling fan may have a post-running time of up to approx. 6 minutes after the engine has been shut off. The time for the electric cooling fan's post-running depends on the engine's temperature, temperature in the engine compartment as well as the pressure level in the AC system.
Substitute Value
- None.
Possible Source
Signal too high:
- Short-circuit to supply voltage in the signal cable.
- Damaged electric cooling fan relay.
Signal too low:
- Short-circuit to ground in the signal cable.
- Short-circuit to ground in the power supply cable.
- Damaged electric cooling fan relay.
Signal missing:
- Open-circuit in the signal cable.
- Damaged electric cooling fan relay.
Fault symptom[s]
- Electric cooling fan does not operate
