About C1174

C1174 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 C1174 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.

C1174 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 park brake switch applied circuit tells the chassis control module, commonly the ABS/EBCM, instrument cluster, or body control module, that the parking brake has been applied. This status drives the park brake warning lamp, hill hold and auto vehicle hold strategies, and driveaway alerts. DTC C1174 sets when the module detects a circuit failure on the applied side of park brake switch number 2, typically an open circuit, an out of range condition, or a signal that does not change state when the park brake is operated. When this code is set the park brake warning lamp may not illuminate whe...
