ECA PWM Output frequency fault
â–¶ How to fix
Check the wiring and connectors on TMS (E5) and the clutch actuator (ECA). Replace the TMS (E5)
What you'll see
No driver-visible symptom recorded.
System reaction
No reaction
Diagnostic depth
Detection
An electrical PWM signal is sent from the TMS to the ECA for safety purposes. The TMS internal circuitry measures the PWM frequency output on the designated pin and compares it with the requested frequency. If the difference is bigger than a threshold value a fault code is set.
Possible cause
Possible short circuit or faulty ECU Hardware.
