About B1567

B1567 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1567 is stored, the module has detected a signal or supply voltage higher than the expected operating range.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1567 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The B1567 fault code indicates that the Body Control Module (BCM) has detected an electrical failure in the high beam headlamp supply circuit. The BCM monitors current draw and voltage on the high beam output to verify normal operation of both high beam bulbs whenever they are commanded on. The code is set when the module sees an open circuit, a short to ground, a short to power, or excessive current draw on the high beam circuit. When this code is active the driver may notice that the high beams do not illuminate, that one or both high beams flicker, that they remain on continuously, or that ...
