About C1167

C1167 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 C1167 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.

C1167 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 second stop lamp switch circuit, the redundant brake pedal switch monitored by the chassis control module, typically the ABS or stability control unit. Many modern systems use two stop lamp switch contacts, one normally open and one normally closed, so the module can cross check the brake applied state for safety critical functions. DTC C1167 sets when the module detects an electrical failure in the stop lamp switch 2 circuit, such as an open circuit, a short to ground, a short to voltage, or a signal that disagrees with stop lamp switch 1. Switch 2 is usually part of ...
