What does it mean?
B1267 is a Body (airbags, seat belts, body electronics) fault code. It indicates: Left Rear Heated Seat Lo Indicator Control Circuit Low .
Symptoms
- The low setting indicator on the left rear seat heater switch does not light, or stays lit permanently
- The left rear seat heater may not work on the low setting
- Switch backlighting or other indicators on the same panel behave oddly
- The right rear seat heater usually still works normally
- The code returns as soon as it is cleared
Likely causes
- Indicator control wire shorted to ground between the module and the left rear seat heater switch
- Failed indicator lamp or its driver inside the switch assembly
- Corroded or wet connector under the rear seat cushion
- Harness pinched by the seat frame or crushed by cargo in the rear footwell
- Wiring damaged during rear seat removal or child seat installation
- Internal fault in the module output that drives the seat heater indicators
How to fix it
- Operate the left rear seat heater through all settings and observe which indicators respond
- Unplug the switch connector and see whether the code changes, which points to the switch assembly
- With the module connector released, measure the indicator control wire for a short to ground
- Inspect the harness and connector under the seat for moisture, corrosion, or crushing
- Repair the shorted wire, or replace the switch panel if its indicator driver has failed
- Clear the code, verify indicator operation, and confirm the seat actually heats up
