About C1163

C1163 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 C1163 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

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.

C1163 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 park brake switch circuit, specifically the second switch or second pole used to confirm the applied (on) state of the parking brake. Many systems use a dual switch or dual contact arrangement so the control module can cross check that the park brake is applied or released, and switch 2 provides the redundant applied signal. DTC C1163 sets when the control module detects an electrical failure in the park brake switch 2 applied circuit, such as an open circuit, a short to ground, a short to voltage, or a signal that disagrees with the companion switch or with vehicle da...
