• A short to ground on the L sense lead
• A damaged L circuit connector
• A failed cell tap on the L channel
• A sense module driver fault on L

What to do next

1. Read L circuit voltage on a scan tool
2. Test the L sense circuit for an open
3. Check the L connector pins for damage
4. Measure the L tap voltage at the pack
5. Replace the sense module if the L channel is dead
