Fault-Tracing Information

Fault-tracing information

Condition

Note! The condenser fan does not start. The compressor runs (starts).




To activate the condenser fan:
- engine running
- generator D+ functioning
- blower fan switch not in position 0
- A/C switch ON.
- evaporator temperature ≤ +1°C (gasoline) ≤ +3°C (diesel).
The above requirements can be checked in the scrolling list using the Volvo Scan Tool (ST).
When all conditions are met the ECC control module sends approximately 12 V to the condenser fan relay in the integrated relay/fusebox in the engine compartment, which activates the condenser fan (and to the FENIX control module, as a request to start the compressor).

Possible source
- Fault in fuse 15 (30A) in the integrated relay / fusebox (11/A) in the engine compartment.
- Fault in condenser fan relay in the integrated relay / fusebox (11/A) in the engine compartment.
- Fault in the condenser fan.
- Open-circuit in the cable between the pressure switch and condenser fan relay.
- Open-circuit in the cable between the condenser fan relay and the condenser fan.
- Open-circuit between ground and the condenser fan relay.

Fault symptom[s]
- The condenser fan does not start.
