If you notice the Engine Light ON, it could be a sign of u2602 fault code.

Here are the symptoms to look out for:

  • The U2602 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, issues with the transmission, problems with the ABS system, issues with the traction control system, and problems with the stability control system.
  • It can also cause issues with the cruise control system and the powertrain control module.
  • These symptoms can indicate a range of issues, including faulty sensors, damaged wiring, or problems with the control module.
  • It is important to have the issue diagnosed and repaired as soon as possible to prevent further damage to the vehicle.

The automobile fault code u2602 can be caused by various issues related to the HybridEV Powertrain Control Module 2.

  • The automobile fault code u2602 can be caused by a faulty Hybrid/EV Powertrain Control Module 2.
  • It can also be caused by an open or shorted Hybrid/EV Powertrain Control Module 2 harness.
  • Additionally, a poor electrical connection in the Hybrid/EV Powertrain Control Module 2 circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code u2602, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u2602, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 diagnosing and fixing the automobile fault code U2602 based on a repair time of 1.0 hour are: – The hourly rate charged by the auto repair shop, which can range from $75 to $150 per hour. – The complexity of the issue causing the fault code.

– The availability and cost of replacement parts, if needed.

– The experience and expertise of the mechanic performing the repair.

– The location of the auto repair shop, as labor rates can vary by region.

The u2602 fault code is related to the loss of communication between the Battery Energy Control Module and the HybridEV Powertrain Control Module 2. Devices connected to the serial data circuits monitor for serial data communications during normal vehicle operation. The Battery Energy Control Module supervises a periodic serial data message to check the communication status of the HybridEV Powertrain Control Module 2.

If the supervised periodic message is not received within 400 ms, the Battery Energy Control Module increases its fail count.

When the fail count is over X Cal Value (7) during Y Cal Value (10 samples), the diagnostic status of this code is set to Failed and transmitted over high voltage energy high-speed GMLAN bus to the HybridEV Powertrain Control Module 2.

The Diagnostic Trouble Code (DTC) will set when a supervised periodic message that includes the transmitter device availability has not been received within 400 ms.

What are the possible causes of the u2602 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u2602 fault code. This code is caused by a faulty Hybrid/EV Powertrain Control Module 2, an open or shorted harness, or poor electrical connection in the circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
