Details of the b118d OBD Code
Code B118D relates to a fault in the climate control temperature sensor circuit.
OBD code B118D means Solar Load Sensor Circuit Low.
This code is triggered by the Body Control Module (BCM) when it detects a low voltage signal from the solar load sensor circuit.
The solar load sensor is part of the HVAC system and helps regulate the interior temperature of the vehicle based on sunlight intensity.
When the BCM receives a low voltage signal from the sensor circuit, it sets code B118D to indicate a potential issue with the solar load sensor or its circuit.
Mechanic’s Tech Notes
Code B118D relates to a fault in the driver’s side impact sensor circuit.
OBDII code B118D indicates a problem with the transmission control module (TCM) power circuit.
To diagnose, use a multimeter to check TCM power and ground connections for proper voltage and continuity.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
Visually inspect wiring harnesses and connectors for damage, and ensure connector pins are not broken, bent, or corroded.
If everything looks good, consider reprogramming or replacing the TCM.
