Bendix EC-60 UDS 238 / SPN 615 FMI 14 — Maximum number of PCV cycles reached

Code Details

Plain-English Meaning

The EC-60 logged that the PCV (pressure control valve) has reached its maximum cycle count threshold. This is an informational/maintenance flag — the valve has operated enough times that Bendix recommends inspection or replacement before reliability is affected.

The Bendix EC-60 table maps UDS code 238, blink code 13-26, J1587 155-14, and J1939 SPN 615 FMI 14 to this ABS/ATC/ESP diagnostic entry. The Bendix source does not mark both warning-lamp columns as active for this entry, but ABS and stability concerns should still be treated conservatively. 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

• Code present; no immediate ABS or brake complaint
• ABS and ATC continue to operate normally
• Lamp status depends on EC-60 configuration — may or may not turn a warning lamp on
• Condition represents accumulated service life, not a current failure

Possible Causes

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

• Normal high-mileage or high-cycle usage of the valve
• Extended operation in severe ATC or ABS activation environments (off-highway, mountainous routes, repeated heavy stops)
• Cycle counter not reset after valve replacement

First Checks

• Inspect the indicated valve for any signs of leakage, slow operation, or mechanical wear.
• If the valve is replaced, reset the cycle counter in the EC-60 using Bendix ACOM.
• Review the vehicle's operating history — frequent ATC or ABS activation accelerates cycle count.
• Clear the code after inspection or replacement and verify no other active faults.

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.
