Details of the c1802 OBD Code
Code C1802 relates to the driver’s airbag circuit resistance being too high.
OBD code C1802 means Steering Angle Sensor Internal fault.
This code is triggered by the steering angle sensor module when it detects an internal fault within the sensor itself.
The steering angle sensor is a critical component of the vehicle’s stability control system, providing data on the steering wheel position and rate of turn to the electronic stability control system.
When the sensor malfunctions internally, it can lead to stability control system issues and potentially affect the vehicle’s handling and safety.
Mechanic’s Tech Notes
Code C1802 relates to the driver’s airbag deployment loop resistance being too high.
To diagnose and fix OBDII code C1802, 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 can help identify and resolve the issue causing the C1802 fault code.
