Details of the b1124 OBD Code
B1124 indicates a fault with the airbag crash sensor 1 circuit.
OBD code B1124 means Sunload Sensor 1 Circuit Short to Ground.
This code is triggered by the Body Control Module (BCM) when it detects a short to ground in the circuit of the sunload sensor 1. The sunload sensor measures the intensity of sunlight entering the vehicle and helps the HVAC system adjust the temperature and airflow accordingly.
When a short to ground is detected in this circuit, it can affect the accuracy of the sensor readings and impact the HVAC system’s performance.
Mechanic’s Tech Notes
Code B1124 indicates a fault with the airbag crash sensor 1 circuit.
To diagnose and fix OBDII code B1124, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.
This thorough inspection will help identify and address any issues causing the B1124 fault code.
