Do not driveTo the nearest safe stop
SPN 524272 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by Meritor (ex-WABCO), and what the second half of the code (FMI) means.
| FMI 0 | Checksum Error of Parameter group 'ECU Supply Voltage' |
| FMI 1 | Checksum Error of Parameter group 'Hardware Configuration Axle Modulator' |
| FMI 2 | Checksum Error of Parameter group 'Parameter Plausibility Storage' |
| FMI 3 | Checksum Error of Parameter group 'Pressure Increase Assist' |
| FMI 4 | Checksum Error of Parameter group 'System Bus Configuration' |
| FMI 5 | Checksum Error of Parameter group 'Brake Pedal Storage' |
| FMI 6 | group 'Modulator Identification' |
| FMI 7 | of Parameter group 'Parameter Plausibility' |
Do not drive. Stop as soon as it’s safe to do so — don’t keep going.
The code is flagged critical: the manufacturer considers it unsafe to keep driving without checking.
This code alone cannot say what will fail next, so stop at the first safe opportunity and look at it on the spot.
That said, the manufacturer flags this code as critical — if in doubt, it is safer to stop and check on the spot.
