About C1176

C1176 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 C1176 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; and 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.

C1176 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 ABS/EBCM reads the left rear wheel speed sensor to determine individual wheel speed for antilock braking, traction control, and stability control. This sensor is normally an active hall effect or magnetoresistive type that draws a small supply current and returns a square wave signal as the tone ring or encoder rotates past it. DTC C1176 sets specifically when the module detects an open circuit on the left rear wheel speed sensor, meaning there is a break in the supply or signal wiring, the connector has lost contact, or the sensor itself has gone open internally. When this code is set the...
