B1972 code definition

The B1972 trouble code detects a passenger rear seat up switch circuit failure.

What the B1972 code means

The B1972 code is a generic OBD-II trouble code that notes a circuit error in the passenger rear seat up switch system. This switch is used to control the height of the rear section of the front passenger seat cushion. The switch is usually located on the outboard side of the front passenger seat, and pressing the switch will move the back part of the seat cushion up. If a circuit error for the passenger rear seat up switch is detected by the body control module or powertrain control module (PCM), then the B1972 trouble code could be stored.

What causes the B1972 code?

The B1972 trouble code has two common causes. The first common cause is damaged electrical parts, such as wires, fuses, and connectors, either in the passenger rear seat up switch, or in the power seat system. The second common cause is a defective passenger rear seat up switch. The code can also be triggered by a faulty body control module, though this is very rare.

What are the symptoms of the B1972 code?

If the B1972 code is detected, then it is likely that the front passenger seat cushion will not be able to be adjusted vertically. The seat up switch will almost surely not work, but the seat down switch will likely fail as well. The code may also be accompanied by an illuminated check engine soon warning light on the gauge cluster.

How does a mechanic diagnose the B1972 code?

The B1972 trouble code will be diagnosed with the help of a standard OBD-II trouble code scanner. A certified mechanic will view the freeze frame data from the scanner to gather information about the code, and also to see if any other trouble codes are present. If there are numerous codes detected, then they should be inspected in the order that they appear in. Next, the trouble codes should be reset and the vehicle restarted, so the mechanic can check to see if the B1972 code remains detected. If not, then it was likely inaccurately detected, or is the result of an intermittent issue.

If the code is still present, then all of the electrical components in the power seat and passenger rear seat up switch systems should be visually inspected. If there are any shorted wires, open or corroded connectors, or blown fuses, then they will need to be replaced. If the electrical system is functioning properly, then the issue is most likely a failed rear seat up switch.

After the mechanic makes any replacements or repairs, the codes should again be reset, the vehicle restarted, and the B1972 code searched for again. This will allow the mechanic to know as soon as the issue is completely resolved.

Common mistakes when diagnosing the B1972 code

The most commonly made error when diagnosing this code comes from mechanics not sticking to the OBD-II diagnosis protocol. It is very important to abide by the protocol at all times, as it greatly increases the chances of an accurate and efficient repair.

Fully functional passenger rear seat up switches are often unnecessarily replaced when damaged electrical components are not first inspected.

How serious is the B1972 code?

The B1972 trouble code will not keep a car form being drivable, or present drivability issues. However, it will likely limit the extent to which the front passenger seat can be adjusted, which can impact passenger comfort. When this code is detected, an inspection should be scheduled, though it is not urgent.

What repairs can fix the B1972 code?
