Volvo All Engines (2004 Emissions) Fault Code: PID 84 FMI 9 Vehicle Speed Status
Posted by PerDiezel Solutions on
Fault Condition: The Vehicle Speed Status code will set when the Engine Management System (EMS) Module has lost the Vehicle Speed Message (J1708) that is sent from the Vehicle Electronic Control Unit (VECU). Engine power will be reduced. Possible repairs: 1) Verify that code PID 84 FMI 9 is set. If code PID 84 FMI 9 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VECU connectors and wires for poor connections.2) If code MID 144 PID 84 is set, repair code MID 144 PID 84 and retest the system. If only...
Volvo All Engines (2004 Emissions) Fault Code: PID 85 FMI 9 Cruise Control Status
Posted by PerDiezel Solutions on
Fault Condition: The Cruise Control Status code will set when the Engine Management System (EMS) Module has lost the Vehicle Speed Status Signal from the Vehicle Electronic Control Unit (VECU). Possible repairs: 1) Verify that code PID 85 is set. If code PID 85 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VECU connectors and wires for poor connections.2) Is code MID 144 PID 84, 86, 91 or PSID 8, 9 is set?If other code(s) MID 144 PID 84, 86, 91 or PSID 8, 9 is set, repair the code(s) MID...
Volvo All Engines (2004 Emissions) Fault Code: PID 91 FMI 9 Pedal Message
Posted by PerDiezel Solutions on
Fault Condition: The Pedal Message code will set when the Engine Management System (EMS) Module has lost the Accelerator Pedal Sensor Signal from the Vehicle Electronic Control Unit (VECU). Possible repairs: 1) Verify that code PID 91 is set. If code PID 91 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VECU connectors and wires for poor connections.2) If code MID 144 PID 91 is set, repair code MID 144 PID 91 and retest the system. If only MID 128 PID 91 is set, the Vehicle Electronic Control Unit (VECU) may...
Volvo All Engines (2004 Emissions) Fault Code: PID 94 FMI 3 Fuel Pressure (FP) Sensor
Posted by PerDiezel Solutions on
Fault Condition: The Electronic Malfunction Lamp (EML) will illuminate when the Fuel Pressure (FP) Sensor signal line voltage is less than 0.3 volts or greater than 4.75 volts. Ifthe signal line voltage returns to between 0.3 volts and 4.75 volts the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Disconnect Engine Management System (EMS) Module connectors B. Check for continuity between Fuel Pressure (FP) Sensor harness connector pin 2 (signal line) and a good ground. If continuity exists, locate and repair the short circuit to ground.2) Disconnect Engine Management System (EMS) Module connector B. Check...
