If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u3501 fault code. Here are the symptoms to look out for:

  • The fault code U3501 is associated with several symptoms, including the engine light being on or the service engine soon warning light being illuminated.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or the transmission slipping.
  • Additionally, the vehicle may experience reduced power or acceleration, stalling or hesitation during acceleration, and decreased fuel efficiency.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

The automobile fault code u3501 can be caused by a faulty control module, open or shorted harness, or poor electrical connection.

  • The automobile fault code U3501 can be caused by a faulty control module that sets the code.
  • Another cause could be an open or shorted control module harness.
  • Additionally, a poor electrical connection in the control module circuit can also trigger this fault code.

To fix the u3501 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code u3501, 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 of the automobile fault code U3501 include the estimated repair time of 1.0 hour and the cost of repair, which is typically between $75 and $150 per hour at most auto repair shops. These factors can influence the overall cost of fixing the issue. It is important to consider both the repair time and cost when diagnosing and fixing the U3501 fault code.

The U3501 fault code is related to the control module supply circuit 1. This code is triggered when the vehicle’s control modules or sensors detect a system voltage of less than approximately 9 volts for about 5 seconds.

The purpose of monitoring the system voltage is to ensure that it is within the normal operating range. If it falls below this range, the U3501 code will be set. This fault code indicates that there is a problem with the control module supply circuit 1, which is causing the voltage to drop below the normal operating range.

It is important to address this issue promptly to prevent further damage to the vehicle’s electrical system.
