Bendix EC-60 UDS 214 / SPN 576 FMI 14 — ATC Disabled or Dynamometer Test Mode Active

Code Details

Plain-English Meaning

The EC-60 is in dyno (dynamometer) test mode, which disables ATC to allow all wheels to spin freely on a chassis dynamometer without triggering false traction control interventions. This is an intentional commanded state — no hardware has failed.

The Bendix EC-60 table maps UDS code 214, blink code 12-03, J1587 017-14, and J1939 SPN 576 FMI 14 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

• All wheels spin freely on a dynamometer without ATC intervention
• No traction control activation when wheels spin
• ABS continues to operate normally
• Condition intentional — set by driver switch or service parameter
• May persist after ignition cycle if set as a permanent EC-60 parameter

Possible Causes

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

• Dyno mode enabled via Bendix ACOM for chassis dynamometer testing
• Feature not reset after dyno test
• Post-service parameter set during an ACOM session not returned to normal

First Checks

• Disable dyno mode via Bendix ACOM after chassis dynamometer testing is complete.
• Connect Bendix ACOM and verify the ATC enable/disable parameter is set to the intended state.
• Confirm no other ATC-affecting faults are present after re-enabling.
• Clear any stored codes after restoring normal configuration.

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.
