The P1EC2 code refers to a problem with the high-voltage energy management communication enable circuit in the battery energy control module of a hybrid vehicle. This circuit is responsible for waking up the battery energy control module for serial data communication when the vehicle is turned on.

The code indicates that there is an issue with the comparison between the high-voltage energy management communication enable hardwire signal and the hybrid powertrain control module 2 serial data message, which should both indicate that the high-voltage energy management communication enable signal is active.

What are the possible causes of the P1EC2 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1EC2 fault code. This code is caused by a faulty Hybrid Powertrain Control Module 2, an open or shorted Hybrid Powertrain Control Module 2 harness, or a poor electrical connection in the Hybrid Powertrain Control Module 2 circuit. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Hybrid Powertrain Control Module 2?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Hybrid Powertrain Control Module 2. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Hybrid Powertrain Control Module 2 harness is open or shorted, or if there is a poor electrical connection in the circuit.
