Volvo All Engines (2004 Emissions) Fault Code: SID 33 FMI 5 Cooling Fan Control
Fault Condition: When the Engine Management System (EMS) Module detects there is a short to voltage in the cooling fan control circuit. If there is an open circuit, FMI 5 will be set and the fan will operate continuously.
If a customer complains that the fan clutch does not disengage and code SID 33 has not been logged in the EMS Module, the problem may be due to a mechanical failure in the chassis air system.
Possible repairs:
Warning: The fan can engage without warning. Hands, arms and personal items can easily be entangled in the belts or fan blades. Keep arms, hair, clothing, jewelry, etc. clear from the fan and belts when the engine is running.
Turn the ignition key OFF first.
1) Disconnect connector from the Fan Clutch Solenoid connector and the Engine Management System (EMS) Module connector B. Measure the voltage between the Fan Clutch Solenoid harness connector pin 3 and a good ground. If voltage is present, the signal line circuit is shorted to voltage. Locate the short to voltage, repair the circuit and retest the system. If there is NO voltage present, replace the Fan Clutch Solenoid and retest the system. If the FMI 3 is still active after replacing the solenoid, verify the diagnostic code, the FMI and retest the system. If the FMI 3 is still active, replace the EMS Module and retest the system.
2) Disconnect connector from the Fan Clutch Solenoid. Turn the ignition key ON. Measure the voltage between Fan Clutch Solenoid connector pin 4 and a good ground. If 12 volts is not present, then there is an open or short in the voltage circuit to the solenoid. Locate and repair the open or short circuit.
3) Disconnect the connector from the Fan Clutch Solenoid. Check for continuity between the Fan Clutch Solenoid pins 3 and 4. If there is NO continuity, replace the Fan Clutch Solenoid and retest the system.
4) Disconnect connector from the Fan Clutch Solenoid connector and the Engine Management System (EMS) Module connector B. Check for continuity between the Fan Clutch Solenoid harness connector pin 3 and the
EMS Module harness connector B pin 49. If there is NO continuity, locate and repair the open in the circuit.
5) Disconnect EMS Module connector B. Visually inspect EMS Module connector B for dirt, loose pins or deformed contacts. If a repairable open is found or the terminal feels loose, repair the harness connector.
If the test lead is making good contact with the connector terminal, verify the diagnostic code, the FMI and retest the system. If the FMI 5 is still active, replace the EMS Module and retest the system.
