The fault code U3505 is a diagnostic trouble code related to the ABS control module. The estimated repair time for this code is 1.0 hour.

The cost of fixing this code is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the fixing cost of U3505 can range from $75 to $150 depending on the repair time required.

The U3505 fault code is related to the control module supply circuit 2. 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 U3505 code will be set. This fault code indicates that there is a problem with the control module supply circuit 2, and it is important to address this issue promptly to avoid further damage to the vehicle.
