Hybrid/EV Battery Voltage Sense L Circuit High

Check these first

• An L tap reading above the surrounding cell voltages
• A short to voltage on the L sense lead
• A corroded L connector adding resistance
• An overcharged cell at the L tap
• A sense module input fault on L

What to do next

1. Read L circuit voltage on a scan tool
2. Compare the L reading to its paired tap
3. Inspect the L sense lead for a short to voltage
4. Measure the L tap directly at the pack
5. Replace the sense module if the L channel reads high
6. Clear the code and retest
