Fault Condition: Code PID 412 will set with FMI 0 if the EGR ECU detects the exhaust gas temperature exceeds 365°F (185°C) for 30 minutes, 410°F (210°C) for 25 seconds or 455°F (235°C) for 3 seconds. Code PID 412 will set with FMI 3 if the EGR ECU detects a short circuit to voltage in the exhaust gas temperature probe circuit. Code PID 412 will set with FMI 4 if the EGR ECU detects a short circuit to ground in the exhaust gas temperature probe circuit. Code PID 412 will set with FMI 5 if the EGR ECU detects an...

Volvo All Engines (2004 Emissions) Fault Code: PID 49 FMI 9 ABS Status Fault Condition: The ABS Status code will set when the EMS Module has lost the ABS Status Signal from the ABS ECU. Possible repairs: 1)Verify that code PID 49 is set. If code PID 49 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the ABS connectors and wires for poor connections.2) Turn the ignition key off and connect a diagnostic computer. Turn the ignition key ON. Use the diagnostic computer to attempt to communicate with the ABS ECU.If communication...

Fault Condition: The AC System Status code will set when the Engine Management System (EMS) Module has lost the AC Status ON/OFF Signal from the Vehicle Electronic Control Unit (VECU). Possible repairs: 1) Verify that code PID 50 is set. If code PID 50 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...

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...

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...
