Volvo All Engines (2004 Emissions) Fault Code: PID 85 FMI 9 Cruise Control Status

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 144 PID 84, 86, 91 or PSID 8, 9 first then retest the system.
If only MID 128 PID 85 is set, the Vehicle Electronic Control Unit (VECU) may be faulty, call MACK Reliability Engineering.
