Bendix EC-60 UDS 64 / SPN 1059 FMI 2 — Open or Shorted Load Sensor

Code Details

Plain-English Meaning

The EC-60 detected a fault in the brake demand or load sensor circuit — Open or Shorted Load Sensor. These sensors inform the EC-60 about brake pedal application force or vehicle load, data used to optimize ATC and ESP brake force strategies.

The Bendix EC-60 table maps UDS code 64, blink code 24-03, J1587 069-02, and J1939 SPN 1059 FMI 2 to this ABS/ATC/ESP diagnostic entry. The Bendix source indicates an ABS and/or ATC/ESP warning lamp can be on for this entry. The EC-60 continuously monitors wheel speed sensor circuits, pressure modulation valve output drivers, supply voltage quality, J1939 network data from the engine and transmission controllers, and internal self-diagnostic routines. When any monitored value falls outside its acceptable range — or a circuit does not respond as the module expects — the EC-60 logs a diagnostic trouble code and may disable the affected ABS, ATC, or ESP function. Bendix ACOM Pro or a compatible diagnostic interface is the required tool for reading live sensor data, running actuator tests, performing calibrations, clearing latched codes, and adjusting EC-60 configuration parameters. Generic J1939 scan tools can read the SPN/FMI but cannot access EC-60-specific live data screens or configuration settings.

Common Symptoms

• ATC/ESP lamp on
• Stability and traction functions may operate in a degraded mode
• ABS continues to operate normally
• No change to normal brake pedal feel
• Code may correlate with sensor replacement or suspension service

Possible Causes

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

• Brake demand or load sensor circuit fault
• Corroded or loose sensor connector
• Sensor physically damaged or mounting disturbed
• Air pressure supply to a pneumatic load sensor out of range
• Harness damage between sensor and EC-60

First Checks

• Inspect the sensor connector and mounting for damage or loose hardware.
• Check sensor supply voltage and ground at the connector.
• Use Bendix ACOM live data to view sensor output — compare primary and secondary readings if both are present.
• Confirm the reading is stable and within the expected range for current brake conditions.
• Clear and recheck after repairs; if a plausibility fault immediately returns, check both sensor harnesses against the wiring diagram.

Can I Keep Driving?

ABS, ATC, and ESP brake-system codes should be handled conservatively. Normal base braking continues when ABS or stability functions are disabled, but the safety benefit of anti-lock and stability intervention is not available. If a brake warning lamp, red stop indicator, loss of braking performance, steering concern, or uncharacteristic vehicle behavior appears alongside this code, stop safely and follow OEM or fleet guidance before continuing.
