[SOLVED] U1516 Code: Fixing Body Control Module Communication With Battery Sensor

The automobile fault code U1516 indicates a problem with the Battery Sensor Module or its related components. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty Battery Sensor Module, an open or shorted harness, poor electrical connection, or a faulty Body Control Module (BCM).

The repair importance is high as it can affect the performance of the vehicle.

The difficulty level of the repair is moderate, and it takes approximately 1.0 hour to fix.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of u1516 fault code.

Here are the symptoms to look out for:

  • The U1516 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or the transmission slipping.
  • The vehicle may also experience problems with the speedometer, such as it not working or displaying incorrect readings.
  • Additionally, the vehicle’s ABS system may not function properly, and the traction control system may be disabled.
  • Finally, the vehicle may experience issues with the power steering, such as difficulty turning or a loss of power steering altogether.

The automobile fault code u1516 can be caused by a faulty battery sensor module, open or shorted harness, poor electrical connection, or a faulty body control module (BCM).

  • The automobile fault code U1516 can be caused by a faulty Battery Sensor Module.
  • It can also be caused by an open or shorted Battery Sensor Module harness.
  • Poor electrical connection in the Battery Sensor Module circuit can also trigger this fault code.
  • Lastly, a faulty Body Control Module (BCM) can also be a cause of the U1516 fault code.

Below are some possible fixes for the automobile fault code u1516, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1516, 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 U1516 indicates a communication error between the vehicle’s electronic control module and the keyless entry system.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code is dependent 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 of fixing this fault code include the severity of the issue, the type of vehicle, and the availability of replacement parts.

The U1516 code is related to the Local Interconnect Network (LIN) Bus.

LIN Bus is a single wire with a transmission rate of 10.417 Kbits. The U1516 code is set when the Body Control Module (BCM) loses communication with the Battery Sensor Module on the LIN Bus. This code indicates that the supervised periodic message from the Battery Sensor Module to the BCM has not been received.

If the serial data communication is lost between any of the LIN devices on the LIN bus network, the master control module will set a no communication code against the non-communicating LIN device.

What are the possible causes of the u1516 automobile fault code that triggers the engine light or service engine soon warning light?

If you’re experiencing the u1516 fault code, your engine light or service engine soon warning light may turn on. This could be due to a faulty Battery Sensor Module, an open or shorted Battery Sensor Module harness, a poor electrical connection in the Battery Sensor Module circuit, or a faulty Body Control Module (BCM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.

How can one fix the u1516 automobile fault code, and what steps should be taken to ensure that the issue is resolved?

If you’re experiencing the u1516 fault code, which is indicated by the engine light being on, it’s likely due to a faulty battery sensor module, an open or shorted harness, poor electrical connection, or a faulty body control module. To fix the issue, start by visually inspecting the wiring harness and connectors, checking for any damaged components or broken, bent, pushed out, or corroded connector pins.

Is it necessary to visually inspect the related wiring harness and connectors when fixing the u1516 automobile fault code, and what should one look for during the inspection?

When fixing the u1516 automobile fault code, it is important to 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 is necessary because a faulty Battery Sensor Module, open or shorted harness, poor electrical connection, or a faulty Body Control Module (BCM) can cause the engine light to turn on. Check the “Possible Causes” listed above and inspect the wiring harness and connectors to fix the issue.
