C1170 — PRNDL Switch Circuit Failure

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

About C1170

C1170 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 C1170 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

C1170 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

This code relates to the steering angle sensor circuit, the sensor mounted in the steering column that reports steering wheel angle and rate of turn to the stability control module. The electronic stability control and traction control systems use steering angle together with yaw rate, lateral acceleration, and wheel speeds to understand the driver's intended path and to apply individual brakes or reduce engine torque when the vehicle deviates from it. The sensor is usually an optical or magnetic device that communicates with the module by an analog signal or over a serial data link. DTC C1170...
