Low-voltage of Capacitor Module (ECM)

What does 8 mean?

The voltage across the Capacitor Module of the ECM has dropped below its minimum operating voltage. This can indicate an insufficient charge or a problem with the charge circuit.

1. 1

   Measure the voltage across the Capacitor Modules.

2. 2

   Check the ECM control module's charging circuit and its input power supply.

3. 3

   Ensure continuous power supply to the ECM is stable.
