[SOLVED] U019B Code: How To Fix Lost Communication With Battery Charger

The automobile fault code U019B indicates a problem with the Battery Charger Control Module (BCCM). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this issue could be a faulty BCCM, an open or shorted BCCM harness, or a poor electrical connection in the BCCM circuit. The importance of repairing this issue lies in the fact that it can affect the battery charging system, leading to battery failure and other electrical problems.

The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be around 1.0 hour. To interpret the fault code, one needs to use an OBD-II scanner or code reader.

If you notice the Engine Light ON, it could be a sign of u019b fault code. Here are the symptoms to look out for:

  • The U019B 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 fuel system, difficulty starting the engine, reduced fuel efficiency, and rough idling.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The u019b automobile fault code can be caused by a faulty BCCM, open or shorted harness, or poor electrical connection.

  • The automobile fault code u019b can be caused by a faulty Battery Charger Control Module (BCCM).
  • It can also be caused by an open or shorted Battery Charger Control Module harness.
  • Additionally, a poor electrical connection in the Battery Charger Control Module circuit can also trigger this fault code.

To fix the u019b automobile fault code, check the possible causes and inspect the related wiring harness, connectors, and components for damage.

  • To fix the automobile fault code u019b, you need to check the possible causes listed above.
  • 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 factors that influence the cost of diagnosing and fixing the u019b automobile fault code based on the estimated 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 U019B fault code is related to the Powertrain Control Module (PCM) in an automobile. The PCM is responsible for monitoring the Controller Area Network (CAN) for messages from the Battery Charger Control Module (BCCM).

If the PCM does not receive the BCCM message within the defined amount of time, the U019B Diagnostic Trouble Code (DTC) is set. This fault code indicates that there is a lost communication with the Battery Charger Control Module.

What are the possible causes of the u019b automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u019b fault code. This code is usually caused by a faulty Battery Charger Control Module (BCCM), an open or shorted BCCM harness, or poor electrical connection in the BCCM 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.

How can one visually inspect the related wiring harness and connectors to fix the u019b fault code?

If you’re experiencing the u019b fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few possible causes. One of them is a faulty Battery Charger Control Module (BCCM), an open or shorted BCCM harness, or a poor electrical connection in the BCCM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the signs of damaged components that one should look for when fixing the u019b fault code?

If you’re dealing with the u019b fault code, keep an eye out for the engine light turning on or the service engine soon warning light. These could be signs of a faulty Battery Charger Control Module (BCCM), an open or shorted BCCM harness, or poor electrical connection in the BCCM circuit. To fix the issue, inspect the wiring harness and connectors for any damage, such as broken, bent, pushed out, or corroded pins. Check the “Possible Causes” listed above for more information.
