Parking Brake Switch #2 Circuit Failure
Diagnostic trouble code C1162 indicates a fault in the parking brake switch #2 circuit. This code is specific to Ford vehicles and is triggered when the circuit remains in a released state abnormally or fails to respond correctly to expected state changes. The control module (typically the ABS module or instrument cluster) monitors this switch to determine if the parking brake is applied or released. A persistent discrepancy in the #2 circuit sets this DTC.
1. Commonly Affected Makes
2. Most Common Causes
- Faulty or misadjusted parking brake switch #2
- Open, short-to-ground, or short-to-voltage in the switch #2 circuit wiring
- Corroded, loose, or damaged switch connector
- Faulty control module (ABS, IPC, or parking brake module)
- Mechanical issue in the parking brake mechanism affecting switch actuation
3. Symptoms You Will Notice
- Parking brake warning light illuminated on the dashboard
- Possible ABS or brake system warning light
- Parking brake may not engage or disengage properly
4. Step-by-Step Diagnosis
Scan for additional codes and verify C1162 is present
Inspect parking brake switch #2 and its connector for damage or corrosion
Test switch operation with a multimeter: check for continuity when applied and released
Check wiring for opens, shorts, or resistance between switch and control module
If wiring and switch are good, suspect a faulty control module
