Conditions Which Generate This Code:
The ECM detects one of the following conditions:
• The “Soft Vehicle Speed Limit” parameter is programmed to “No” and the vehicle speed
exceeds the programmed “Vehicle Speed Limit” by more than 10 MPH for more than 20 seconds.
• The “Soft Vehicle Speed Limit” parameter is programmed to “Yes” and the vehicle speed exceeds the programmed “Vehicle Speed Limit” by more than 15 MPH for more than 20 seconds.
System Response:
The ECM will not energize the injector solenoids while the diagnostic code is active. “VEHICLE
SPEED LIMIT” will be displayed on the status screen when the vehicle speed limit is exceeded.
Customer passwords are required to clear this code.
Possible Performance Effect:
Injection is disabled until the vehicle speed falls below the programmed “Vehicle Speed Limit”.
Troubleshooting:
This diagnostic code does not necessarily indicate that there is an electronic problem. If the vehicle
speed calibration is wrong, perform the following procedure:
Perform the following diagnostic procedure: “Vehicle Speed Circuit – Calibrate”
Results:
• OK – STOP.
