What Does C1167 Mean?
This code indicates the park brake actuator assembly switch released position circuit is shorted to ground. The released position switch confirms the parking brake is fully disengaged. A short to ground on this circuit falsely indicates the parking brake is in the released position at all times, or prevents the module from accurately reading the switch state.
Common Causes
35%
Chafed wiring from the actuator switch contacting a grounded metal surface near the parking brake mechanism
25%
Failed actuator switch with internal short to ground
25%
Corroded connector allowing moisture to bridge the signal pin to the grounded connector shell
15%
Pinched wire near the parking brake mechanism or underbody mounting point
Diagnostic Steps
1
Step 1: Disconnect the actuator switch and check if the code changes. If the short clears with the switch disconnected, the switch is internally shorted.
2
Step 2: With the switch disconnected, measure resistance from the released position signal wire to chassis ground at the module connector.
3
Step 3: Inspect the wiring harness along the parking brake mechanism and underbody for chafing or compression damage.
4
Step 4: Test the switch for proper operation and check for internal short to its housing ground.
5
Step 5: Repair or replace the faulty component, clear codes, and verify proper parking brake status indication.

The most common cause of C1167 (Park Brake Actuator Assembly Switch Released Circuit Short to Gnd) is: Chafed wiring from the actuator switch contacting a grounded metal surface near the parking brake mechanism
Typical repair costs for C1167 range from $80 to $300, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Parking brake status indication may be inaccurate. The brake warning lamp may not illuminate when the parking brake is applied. Repair within one week.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1167 to identify the root cause.
