What Does C1162 Mean?
This code indicates the control module has detected a failure in the park brake switch #2 released position circuit. Park brake switch #2 monitors the parking brake in its released (disengaged) position. When this circuit fails, the module cannot confirm that the parking brake has been fully released, which may affect ABS operation and prevent the brake warning lamp from extinguishing.
Common Causes
35%
Failed park brake switch #2 due to internal contact wear from repeated cycling
25%
Misadjusted parking brake mechanism causing the switch to not reach the released detection point
20%
Corroded or damaged wiring at the switch from exposure to road spray and moisture
15%
Loose connector preventing reliable electrical contact at the switch
5%
Module internal fault on the switch input circuit
Diagnostic Steps
1
Step 1: Apply and fully release the parking brake. Observe whether the brake warning lamp on the dashboard properly turns off when released. A lamp that stays on suggests the switch is not detecting the released position.
2
Step 2: Locate park brake switch #2 and disconnect it. Measure continuity while manually actuating the switch. It should show continuity in one position and open in the other.
3
Step 3: With the switch connected, backprobe the signal wire and verify voltage changes when the parking brake is applied and released.
4
Step 4: Check for proper parking brake cable adjustment. If the cable is too loose, the switch may not travel to its released position.
5
Step 5: Repair, adjust, or replace the switch, clear codes, and verify proper park brake status in live data.

The most common cause of C1162 (Park Brake Switch # 2 Released Circuit Failure) is: Failed park brake switch #2 due to internal contact wear from repeated cycling
Typical repair costs for C1162 range from $50 to $200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The brake warning lamp may remain illuminated even with the parking brake released, potentially masking other brake system warnings. ABS operation 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 C1162 to identify the root cause.
