The automobile fault code U1550 indicates a problem with the driver seat heating and cooling switch or its related components. The most common symptom is the illumination of the engine light or service engine soon warning light. The cause could be a faulty switch, an open or shorted harness, poor electrical connection, or a faulty body control module.

The repair importance is moderate, as it affects the comfort of the driver, but it does not pose a safety risk. The repair difficulty is low, and it takes approximately 1.0 hour to fix. To interpret the fault code, one should check the possible causes listed above and visually inspect the related wiring harness and connectors.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u1550 fault code. Here are the symptoms to look out for:

  • The U1550 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, issues with the transmission, problems with the ABS system, issues with the speedometer, problems with the cruise control, and issues with the stability control system.
  • It is important to get this fault code diagnosed and fixed as soon as possible to avoid further damage to the vehicle.

The automobile fault code u1550 can be caused by a range of issues, including a faulty driver seat heating and cooling switch, open or shorted harness, poor electrical connection, and a faulty body control module (BCM).

  • The automobile fault code U1550 can be caused by a faulty driver seat heating and cooling switch.
  • It can also be caused by an open or shorted driver seat heating and cooling switch harness.
  • Another cause can be a poor electrical connection in the driver seat heating and cooling switch circuit.
  • Lastly, a faulty body control module (BCM) can also trigger the U1550 fault code.

To fix the u1550 fault code, check the possible causes and inspect the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code u1550, 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 automobile fault code U1550 has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of U1550 will range between $75 and $150, depending on the repair time required.

It is important to consider the repair time when estimating the fixing cost of this fault code.

The u1550 fault code is related to the Local Interconnect Network (LIN) Bus.

It occurs when the Body Control Module (BCM) loses communication with the Driver Seat Heating and Cooling Switch on the LIN Bus. This happens when the supervised periodic message from the switch to the BCM is not received. The LIN Bus is a single wire with a transmission rate of 10.417 Kbits used for serial data communication between a master control module and other LIN devices within a subsystem.

When the BCM sets the no communication code against the non-communicating LIN device, the u1550 code is triggered.

What are the possible causes of the u1550 automobile fault code?

If you’re experiencing the u1550 fault code in your automobile, it could be due to a faulty driver seat heating and cooling switch, an open or shorted switch harness, a poor electrical connection in the switch circuit, or a faulty body control module. To fix the 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.
