Code B113E Description
The B113E diagnostic trouble code indicates that the external boot/trunk release switch signal is stuck low. This means that the signal from the switch that activates the boot or trunk release mechanism is not being received properly by the vehicle's control module. This can prevent the boot or trunk from opening when the switch is pressed, causing inconvenience to the driver and potentially limiting access to the storage area.
Common Causes of B113E
- Faulty external boot/trunk release switch.
- Wiring or connection issues between the switch and control module.
- Faulty control module.
- Corrosion or damage to the wiring harness.
- Electrical issues within the vehicle's system.
Symptoms of B113E
- Inability to open the boot or trunk using the external release switch.
- Unresponsive trunk release button on the key fob.
- Warning light on the dashboard indicating a trunk/boot release system fault.
- Audible clicking noise from the trunk latch when attempting to open it.
How to Fix B113E
- Begin by inspecting the external boot/trunk release switch for any visible damage or signs of wear. Replace the switch if necessary.
- Check the wiring and connections between the switch and control module for any breaks or corrosion. Repair or replace as needed.
- Use a diagnostic scan tool to check for any fault codes in the control module related to the trunk release system. Clear any stored codes and test the system.
- If the issue persists, consider replacing the control module responsible for receiving the signal from the switch and activating the trunk release mechanism.
- Test the system thoroughly after repairs to ensure that the trunk/boot release is functioning correctly.
Cost to Fix B113E
