  • The automobile fault code U1885 can be caused by a faulty Hybrid/EV Powertrain Control Module.
  • It can also be caused by an open or shorted Hybrid/EV Powertrain Control Module harness.
  • Another cause can be a poor electrical connection in the Hybrid/EV Powertrain Control Module circuit.
  • Lastly, a faulty Battery Energy Control Module can also trigger this fault code.

Below are the possible fixes for the automobile fault code u1885.

  • To fix the automobile fault code u1885, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • 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 automobile fault code U1885 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the U1885 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The U1885 code is related to the loss of communication with HybridEV Powertrain Control Module 1 on high-speed General Motor Local Area Network (GMLAN) bus. The Battery Energy Control Module supervises a periodic serial data message to check the communication status of the HybridEV Powertrain Control Module 1.

If this message is not received within 3 s, then this Diagnostic Trouble Code (DTC) is set. Devices connected to the serial data circuits monitor for serial data communications during normal vehicle operation. Each message contains the identification number of the transmitter device.

What are the possible causes of the u1885 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u1885 fault code. This code is caused by a faulty Hybrid/EV Powertrain Control Module, an open or shorted Hybrid/EV Powertrain Control Module harness, a poor electrical connection in the Hybrid/EV Powertrain Control Module circuit, or a faulty Battery Energy Control Module. 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 one visually inspect the related wiring harness and connectors to fix the u1885 fault code?

If you’re experiencing the u1885 fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few possible causes. These include a faulty Hybrid/EV Powertrain Control Module, an open or shorted Hybrid/EV Powertrain Control Module harness, a poor electrical connection in the Hybrid/EV Powertrain Control Module circuit, or a faulty Battery Energy Control Module.
