The preheat function is used to warm up the inlet air during cold conditions both before and after cranking to make the starting easier and better for the environment at very low temperatures. This diagnostic trouble code (DTC) detects a faulty preheat function. Conditions for diagnostic trouble code (DTC):1) Preheating requested2) The voltage at pin A14.EB:7 is less than 29?% of the battery voltage Observable symptoms1) Intake air heater (IAH) does not function2) White smoke at cold start3) Difficult to start in extreme cold Probable cause1) Wiring harness2) Connector3) Intake air heater (IAH) relay Volvo All Engines (2010 Emissions) Fault...

This signal is sent from the (VECU) Vehicle Electronic Control Unit to the Cluster to present the actual vehicle speed. It is also used by the maximum speed limitation. The maximum speed limit can vary depending on customer option. Conditions for diagnostic trouble code (DTC):1) No vehicle speed available to VECU Observable symptoms1) None Probable cause1) Vehicle speed sensor2) Vehicle Control Unit (VECU) Volvo All Engines (2010 Emissions) Fault Code: SPN 730 FMI 5 PID: SID 71 Intake Air Heater (IAH) 2 Volvo All Engines (2010 Emissions) Fault Code: SPN 730 FMI 4 PID: SID 71 Intake Air Heater (IAH)...
