Toyota Land Cruiser Prado DTC B126A

Parts:

No specific parts number is required for this DTC code.

Description:

The B126A code is a manufacturer-specific body code related to the body control module (BCM) in your Toyota Land Cruiser Prado. This code is generated when there is an issue with the keyless entry system and the door lock control circuit. The BCM is responsible for controlling the functions of the door locks and keyless entry system, so when it detects a problem, it generates the B126A code.

Symptoms:

When the B126A code is generated, you may experience the following symptoms:

– The malfunction indicator lamp (MIL) on the dashboard may become illuminated.
– The keyless entry system may not work properly, making it difficult to unlock or lock the doors.
– The door locks may not operate correctly, making it difficult to lock or unlock the doors.

Cause:

There are several potential causes of the B126A code, including:

– A faulty door lock actuator. The door lock actuator is responsible for physically locking and unlocking the doors. If it is damaged or malfunctioning, it may cause the B126A code to be generated.
– Wiring issues in the door lock control circuit. If there is a break in the wiring or a loose connection, it may cause the B126A code to be generated.
– A faulty BCM. If the BCM is damaged or malfunctioning, it may not be able to properly control the door locks and keyless entry system, causing the B126A code to be generated.

Possible Location:

The B126A code can be located in the BCM of your Toyota Land Cruiser Prado.

How to Fix the Problem:

To fix the problem, you may try the following steps:

– Check the wiring in the door lock control circuit for any damage or loose connections. Use a digital multimeter to test the continuity of the wiring.
– Check the door lock actuator for any signs of damage or malfunction. If it is damaged or not functioning correctly, replace it.
– If the above steps do not solve the issue, replace the BCM. A faulty BCM may be the root cause of the B126A code.

How Difficult to Fix:

The difficulty level of fixing the problem depends on the root cause of the issue. If it is a simple wiring issue, it can be relatively easy to fix. However, if it is a faulty BCM, it may require more advanced diagnostic skills and specialized tools.

Can You DriveWith This Code:

You can drive with this code, but it is recommended to get it fixed as soon as possible to prevent any further issues with the keyless entry system or door locks. Driving with a faulty keyless entry system or door locks can pose a safety risk, as you may not be able to properly secure your vehicle.

How to Clear the Code:

To clear the code, you can disconnect the battery, but note that this will also reset the relearn of the ECU. This means that the vehicle’s computer will have to relearn certain parameters, such as idle speed and fuel trim, after the battery is reconnected.
It is recommended to use an OBD-II scanner to clear the code. An OBD-II scanner allows you to clear the code without resetting the relearn of the ECU. It also provides a more precise method of clearing codes, as it can identify the exact code that needs to be cleared.

Tools Need to Use:

To diagnose and fix the issue, you may need the following tools:
– Digital multimeter: to test the continuity of the wiring in the door lock control circuit.
– Wiring diagram for the door lock control circuit: to help identify the wiring and connections involved in the circuit.
– OBD-II scanner: to read the code and clear it.

Step-by-Step Diagnostic Procedure:

1. Use an OBD-II scanner to read the code and determine its cause.
2. Check the wiring in the door lock control circuit for any damage or loose connections.
3. Check the door lock actuator for any signs of damage or malfunction.
4. If the above steps do not solve the issue, replace the BCM.
5. Clear the code with an OBD-II scanner to ensure the issue is resolved.

It is important to follow these steps in order to accurately diagnose and fix the issue with the B126A code in your Toyota Land Cruiser Prado. If you are not comfortable working on your vehicle, it is recommended to seek the help of a professional mechanic.
