C1950 — Accelerometer Sensor Circuit Failure

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1950

C1950 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1950 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1950 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 accelerometer, or acceleration sensor, measures vehicle acceleration and deceleration forces and reports them to the control module, which uses the data for crash detection in the restraint system or for stability and rollover control. Unlike a specific open circuit code, DTC C1950 is a general accelerometer circuit failure, set when the module detects an electrical fault such as a short, an implausible or out of range signal, an internal sensor fault, or a loss of the expected sensor data. When this code is set the related safety or stability function is usually disabled and a warning lam...
