Volvo All Engines (2004 Emissions) Fault Code: PID 26 FMI 8 Fan Speed Fault Condition: High engine coolant temperature could occur and cause engine shutdown. If fault code PID 26 is set with FMI 3, fault code SID 211 may also be set. Possible repairs: Turn the ignition key OFF first. 1) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between electronic fan drive harness connector pin 5 and a good ground.If continuity exists, locate and repair the short circuit to ground in the supply voltage circuit between the electronic fan drive and...

Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 354 will set when the EMS Module senses that the Intake Air Temperature and Humidity (IATH) Sensor signal voltage is less than 0.4 volts or greater than 4.2 volts. If the Intake Air Temperature and Humidity (IATH) Sensor voltage returns to between 0.4 volts and 4.2 volts, the fault will become inactive. Note: To ensure that condensation on the sensor has been removed, diagnostics can only be performed after the engine has run for 5 minutes or more. Run the engine for 5 minutes or more and then...

Fault Condition: The Compressor Discharge Temperature code will set if the calculated discharge temperature has exceeded 446°F (230°C) for 25 seconds. The fault will become inactive if the calculated compressor discharge temperature is below 410°F (210°C). Engine power may be reduced when the calculated compressor discharge temperature exceeds 446°F (230°C). This temperature fault code can only be set while the vehicle is driven. Higher horsepower engines may generate excessive compressor discharge temperatures. Refer to message status information rather than fault codes for this situation. Possible repairs: 1) Verify that code PID 404 is set. If code PID 404 is not...
