Do not driveMinutes
J1939 code SPN 575. Below — how the fault is worded at the factory by Renault Trucks, and what the second half of the code (FMI) means in the standard.
| FMI 31 | Inter-axle or inter-wheel lock engaged. Repair: This is not a fault. |
| SPN 575 FMI 31575/31 · 575.31 | condition exists (see manufacturer description) |
Do not drive. Stop as soon as it’s safe to do so — don’t keep going.
Part of the brake circuit or ABS/EBS is out of service. The pedal may still feel normal — until the first emergency stop or descent.
Next comes longer stopping distance, a skid on a slick surface, failure on a long downgrade. This is the case where "I will take it slow" does not work.
Let the air system build to working pressure and listen for leaks. Don’t drive with faulty brakes.
