Code P1E0D GMC Description
The Hybrid/EV Powertrain Control Module 2 performs active isolation testing to monitor the internal Hybrid/EV battery pack HV circuits for chassis isolation. The Hybrid/EV Powertrain Control Module 2 switches fixed resistors between the high voltage system and vehicle chassis. The difference between the switched-to-chassis state and the unswitched state is used to calculate a resistance-to-chassis value. The DTC will be set when the Isolation sensor voltage is greater than 333 V.
What are the Possible Causes of the DTC P1E0D GMC?
- Faulty Hybrid/EV Powertrain Control Module 2
- Hybrid/EV Powertrain Control Module 2 harness is open or shorted
- Hybrid/EV Powertrain Control Module 2 circuit poor electrical connection
