After removing the 36V battery cables from the generator battery, remove both engine wiring harness connectors from the generator control module. Wait at least 5 minutes and then remove the generator control module cover. Verify voltage levels at all 36V, 12V, and 3-phase connections, are less than 3 volts using a DMM before proceeding.
- Perform the Hybrid Battery Service Disconnect/Connect .
- Inspect the connection of 3 phase cables for the proper torque. Refer to Fastener Tightening Specifications .
- If the 3 phase cables are within torque specifications, replace the MGU.
