What Does C1164 Mean?
This code indicates the control module has detected a general circuit failure in the park brake actuator assembly switch circuit. The actuator switch provides feedback about the parking brake position to the ABS/brake module. A circuit failure means the module cannot determine parking brake status, affecting ABS logic and warning lamp operation.
Common Causes
35%
Failed park brake actuator switch from mechanical wear or electrical contact degradation
25%
Corroded or damaged wiring between the actuator switch and control module
20%
Loose, corroded, or water-damaged connector at the actuator switch
15%
Parking brake mechanism not fully engaging or releasing, keeping the switch in an indeterminate position
5%
Control module input circuit failure
Diagnostic Steps
1
Step 1: Cycle the parking brake fully applied and released while monitoring the brake warning lamp. Note any abnormal behavior.
2
Step 2: Locate the actuator switch and disconnect it. Test continuity while manually actuating the switch mechanism through its full travel.
3
Step 3: Verify proper voltage supply at the switch connector from the module. Check for reference voltage presence (typically 5V or 12V).
4
Step 4: Check wiring continuity from the switch to the module connector. Test for opens, shorts to ground, and shorts to battery.
5
Step 5: Verify parking brake cable adjustment is correct, repair or replace the switch, clear codes, and confirm proper operation.

The most common cause of C1164 (Park Brake Actuator Assembly Switch Circuit Failure) is: Failed park brake actuator switch from mechanical wear or electrical contact degradation
Typical repair costs for C1164 range from $80 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Parking brake position cannot be confirmed electronically. Warning lamp may be unreliable. ABS calibration may be affected. 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 C1164 to identify the root cause.
