Battery voltage is monitored by the circuits within the Engine Control Module (ECM). Conditions for diagnostic trouble code (DTC):1) The voltage is more than 19?V Probable cause1) Battery charger connected2) Alternator3) Engine control module (ECM) Volvo All Engines (2010 Emissions) Fault Code: SPN 158 FMI 18 PID: PSID 124 Keyswitch Battery Potential – Moderately Severe Level Volvo All Engines (2010 Emissions) Fault Code: SPN 158 FMI 16 PID: PSID 124 Keyswitch Battery Potential – Moderately Severe Level Volvo All Engines (2010 Emissions) Fault Code: SPN 153 FMI 7 PID: PSID 23 Engine High Resolution Crankcase Pressure Volvo All Engines (2010...

Conditions for diagnostic trouble code (DTC):1) The component is stuck in opened position Observable symptoms1) Engine does not reach normal operating temperature Probable cause1) The thermostat may have seized in open position if the engine has been warmed up too slowly Detailed information1) By comparing calculated and measured coolant temperature on a hot engine, one can determine if engine warm-up occurred sufficiently fast Volvo All Engines (2010 Emissions) Fault Code: SPN 158 FMI 3 PID: PSID 124 Keyswitch Battery Potential Volvo All Engines (2010 Emissions) Fault Code: SPN 158 FMI 18 PID: PSID 124 Keyswitch Battery Potential – Moderately Severe...

Conditions for diagnostic trouble code (DTC):1) The component is stuck in closed position Observable symptoms1) High engine coolant temperature (ECT)2) Drive-abilty effected Probable cause1) If the thermostat is stuck in closed position the engine will not be cooled Detailed information1) The thermostat may have seized in closed position if the coolant temperature continued to rise at the same rate as the oil temperature Volvo All Engines (2010 Emissions) Fault Code: SPN 1659 FMI 12 PID: PSID 109 Engine Coolant System thermostat Volvo All Engines (2010 Emissions) Fault Code: SPN 158 FMI 3 PID: PSID 124 Keyswitch Battery Potential Volvo All...

The (VECU) Vehicle Electronic Control Unit supplies and monitors the cranking signal to the starter motor relay. Several types of starter cranking protection are provided so the starter cannot be engaged in unwanted conditions. The starter cranking protection will also limit the maximum cranking time to 18 seconds without cycling the key. Conditions for diagnostic trouble code (DTC):1) The starter motor has been activated for too long time2) Too many tries to start Observable symptoms1) Not possible to activate the starter motor during a certain time2) Text message on the display, Wait to start, and count down Probable cause1) Engine...
