B1335 code definition

The B1335 trouble code detects an issue with the right rear door ajar circuit.

What the B1335 code means

The B1335 code is a generic OBD-II trouble code that signals a malfunction with the door ajar circuit for the right (passenger side) rear door. When the rear right door is not securely latched, the door ajar Warning Light will illuminate, and possibly show that specific door that is not closed. If the reading from the door ajar right rear circuit is abnormal, then the B1335 trouble code may be triggered.

What causes the B1335 code?

Causes of the B1335 trouble code include:

What are the symptoms of the B1335 code?

When the B1335 trouble code is detected, it’s likely that the door ajar Warning Light will be constantly illuminated on the gauge cluster, because the system will sense that the right rear door is not closed. This warning light will usually stay illuminated even when the vehicle is turned off, and in many cars that means that the cabin lights will remain turned on around the clock. This will drain the battery, and usually leave the battery dead after a few hours of the vehicle being off. If this happens, the vehicle will not be able to start.

How does a mechanic diagnose the B1335 code?

The B1335 code will be diagnosed using a standard OBD-II trouble code scanner. A reputable technician will look at the freeze frame data from the scanner to gather information about the B1335 code, and to see if any other trouble codes have been detected. In the event that numerous codes are present, the mechanic should diagnose them in the order in which the scanner displays them. The codes will then be reset, and the vehicle restarted, so the technician can check to see if the B1335 code is still present. If it is not, then it was likely triggered inaccurately, or represents an intermittent error.

If the code remains detected, then the technician will begin by visually inspecting the electrical components in the system, including all wires, connectors, fuses, and circuits. Any damaged components will need to be replaced.

Next, the mechanic will check the right rear door latch, which may require lubrication if it is jammed. If the latch is in working order, then the right rear door ajar switch should be inspected. If none of these inspections fix the problem, then the door ajar Warning Light dimmer will need to be adjusted.

Any time a component is replaced or repaired, the mechanic will need to check to see if the code is still detected, or the door ajar Warning Light is still illuminated. This will allow the mechanic to know as soon as the issue has been resolved.

Common mistakes when diagnosing the B1335 code

The most common error when diagnosing this code comes from failing to properly follow the OBD-II diagnosis protocol. The diagnosis protocol should always be adhered to by mechanics, as it helps ensure an efficient inspection, and a repair that is free of inaccurate replacements.

Fully operational right rear door ajar switches are frequently replaced when basic electrical malfunctions are overlooked.

How serious is the B1335 code?

It is very possible that the B1335 trouble code will keep a car from turning on, because the interior lights (which often stay on as long as the door ajar Warning Light is illuminated) may have drained the battery. As soon as the B1335 code is detected, an inspection should be scheduled.

What repairs can fix the B1335 code?

Repairs for the B1335 trouble code are:

  • Replacing the right rear door ajar switch
  • Fixing or replacing the right rear door latch
  • Adjusting the door ajar Warning Light dimmer
  • Replacing the fuses, wires, connectors, and/or circuits

Additional comments for consideration regarding the B1335 code

It is sometimes possible for the right rear door ajar switch to be repaired, but it will usually require replacement if at all damaged.
