Detailed guide for SPN 1067 FMI 7
Back to top ↑What SPN 1067 FMI 7 means
SPN 1067 FMI 7 is documented by Volvo Premium Tech Tool for Bendix systems as a brake switch calibration fault.
The code indicates that the brake switch or brake signal has not been calibrated correctly.
What to check first
Make sure the truck air system is fully charged.
With the ignition switched on, wait a few seconds. Press the brake pedal firmly and hold it for approximately five seconds, then release the pedal.
This procedure allows the Bendix system to learn or calibrate the brake switch signal on applicable vehicles.
If the fault remains
If SPN 1067 FMI 7 remains active after calibration, inspect the brake switch, wiring, connectors and related brake signal inputs.
Check for other ABS or brake-system faults that could prevent calibration from completing.
Important
This interpretation is specifically documented for Bendix-equipped Volvo/Mack applications. Other systems may use different diagnostic logic, so verify the brake-system manufacturer before applying the procedure.
