Bendix EC-60 UDS 70 / SPN 1067 FMI 2 — PS Supply Voltage Error

Code Details

Plain-English Meaning

The EC-60 detected a voltage error with the pressure sensor (PS) supply. The PS provides the EC-60 with brake application pressure data used in ATC and ESP strategies.

The Bendix EC-60 table maps UDS code 70, blink code 24-05, J1587 077-02, and J1939 SPN 1067 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
• ATC or ESP operating in a degraded mode
• ABS unaffected
• Code may correlate with sensor replacement or recent service
• Code present consistently or under specific operating conditions

Possible Causes

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

• PS supply voltage outside acceptable range — wiring fault, connector issue, or EC-60 supply output problem
• Corroded or damaged pressure sensor connector
• Damaged harness between pressure sensor and EC-60
• Air supply to the sensor out of range (for pneumatic pressure sensors)
• EC-60 internal supply circuit fault

First Checks

• Measure supply voltage at the PS connector and compare to specification.
• Inspect the PS connector for corrosion and secure connection.
• Check for related voltage supply codes that may point to a shared supply fault.
• Use ACOM live data to view PS output and confirm it reads within expected range.
• Clear and recheck after calibration or wiring repair.

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.
