Bendix EC-60 UDS 37 / SPN 627 FMI 4 Explained

Code Details

Plain-English Meaning

In plain English, this Bendix EC-60 record points to abs power supply diagnostic context. The source-backed label is Battery Voltage Too Low During ABS. That label is a starting point for diagnosis, not proof that a specific part has failed. Symptoms may vary by vehicle configuration, whether the code is active, and whether related ABS, ATC, ESP, power, or J1939 communication codes are present.

The Bendix EC-60 table maps UDS code 37, blink code 06-03, J1587 251-04, and J1939 SPN 627 FMI 4 to this ABS/ATC/ESP diagnostic entry. The Bendix source indicates an ABS and/or ATC/ESP lamp can be on for this entry.

Common Symptoms

• ABS warning lamp or stability-control indicator may be on
• ATC/ESP lamp may be on when equipped and when the fault affects stability or traction functions
• A Bendix-compatible diagnostic tool may show the UDS, blink, J1587, or SPN/FMI code
• Brake and stability behavior may be different from normal depending on the active fault and vehicle configuration
• Symptoms may vary and some codes may be noticed only during a scan

Possible Causes

Possible causes may include the items below. The list is not a parts diagnosis.

• ABS power supply wiring, connector, signal, calibration, or monitored-circuit concerns may be involved
• Power supply, ground, sensor signal, valve circuit, or module communication issues can be related depending on the exact code label
• Moisture, corrosion, damaged harness routing, or intermittent connections can contribute to ABS and stability-system faults
• Configuration, calibration, or vehicle setup issues can be involved for entries marked as configuration, plausibility, or calibration related
• Related J1939, power, wheel speed, brake demand, or modulator codes should be reviewed before drawing conclusions

First Checks

• Treat ABS, ATC, ESP, and brake-related warnings as safety-related.
• Record the Bendix UDS code, blink code, SPN/FMI, J1587 code, active status, warning lamps, and vehicle configuration.
• Check whether related wheel speed, modulator valve, voltage, ECU, J1939, or sensor codes are active.
• Look for obvious harness damage, loose connectors, corrosion, or recent service in the affected area without bypassing safety systems.
• Verify the final diagnostic path with Bendix service information, Bendix-compatible diagnostic software, or a qualified brake-system technician.

Can I Keep Driving?

ABS, ATC, ESP, and brake-system codes should be handled conservatively. If a brake warning, red stop lamp, loss of braking performance, steering concern, oil pressure warning, high coolant temperature warning, or severe derate appears, stop safely and follow OEM or fleet guidance.
