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 the EMS Module.
2) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Turn the ignition key ON. Measure the voltage between electronic fan drive harness connector pin 5 and a good ground.
If voltage is present, locate and repair the short circuit to voltage in the supply voltage circuit between the electronic fan drive and the EMS Module.
3) Disconnect the electronic fan drive harness connector. Check for continuity between the sensor side of electronic fan drive connector pin 5 and a good ground. If continuity exists, replace the electronic fan drive assembly.
4) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Turn the ignition key ON. Measure the voltage between electronic fan drive harness connector pin 1 and a good ground.
If voltage is present, locate and repair the short circuit to voltage in the sensor signal circuit between the electronic fan drive and the EMS Module.
5) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between electronic fan drive harness connector pin 1 and a good ground.
If continuity exists, locate and repair the short circuit in the electronic fan drive signal line.
6) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between EMS Module harness connector A pin 39 and electronic fan drive harness connector pin 2.
If there is NO continuity, locate and repair the open circuit in the electronic fan drive ground line.
7) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between the sensor side of electronic fan drive connector pin 1 and a good ground (see Figure 14).
If continuity exists, replace the electronic fan drive assembly.
8) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between EMS Module harness connector A pin 7 and electronic fan drive harness connector pin 5.
If there is NO continuity, locate and repair the open circuit in the electronic fan drive supply line.
9) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between EMS Module harness connector A pin 35 and electronic fan drive harness connector pin 1.
If there is NO continuity, locate and repair the open circuit in the electronic fan drive signal line.
10) Disconnect EMS Module connector A. Visually inspect the EMS Module and connector A for broken, damaged, or shorted pins. If any damage is found, repair or replace the damaged component.
11) Replace the electronic fan drive with a known good unit. Restore all electrical connections an retest the system. If blink code PID 26 is still active, install the original electronic fan drive and replace the EMS Module.
If blink code PID 26 is NOT active, replacing the electronic fan drive solved the problem. Check all connectors to ensure proper connections.
