Abnormal Charge of Capacitor Module (ECM)

What does E mean?

The Capacitor Modules are not charging as expected. This indicates a problem with the charging process or a fault within the capacitor modules preventing them from holding charge.

• Abnormalities detected during the charging process of the capacitor module.
• Faulty charging circuit or control logic within the ECM.
• Capacitor module has developed internal shorts or leakage.
• Inconsistent charging current or voltage readings from sensors.
• Parameters related to capacitor charging (e.g., P5-xx) are incorrectly configured.

Click steps to track your progress.

1. 1

   Check the power supply connections to the Capacitor Modules.

2. 2

   Verify the functionality of the charging circuit within the ECM control module.

3. 3

   Inspect the Capacitor Modules for physical damage or internal failure.
