  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The factors that influence the cost of fixing the automobile fault code P1EC1 are the estimated repair time and the hourly rate charged by the auto repair shop.

The estimated repair time for this fault code is 1.0 hour.

The cost of fixing the fault code will depend on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the availability of replacement parts.

The P1EC1 code is related to the battery energy control module.

It indicates that the high-voltage energy communication bus enable circuit is experiencing low voltage. This circuit is responsible for waking up the battery energy control module for serial data communication.

The hybrid powertrain control module 2 activates this circuit when the vehicle is on. The battery energy control module compares the high-voltage energy management communication enable hardwire signal with a hybrid powertrain control module 2 serial data message.

What are the possible causes of the P1EC1 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1EC1 fault code. This code is usually 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 visually inspect the related wiring harness and connectors, check for damaged components, and look for 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.
