Brake Pressure Sensor D Missing Calibration
C059D concerns brake pressure sensor d missing calibration. Learn what this fault indicates and where to begin diagnosis.
What you may notice
Symptoms
- 01System warning may illuminate
- 02Affected feature may be unavailable
- 03Symptoms depend on the vehicle
Where to look first
Common causes
- 01Sensor or actuator fault, wiring or connector damage, or an underlying chassis system problem
- 02Module power, ground, or connector fault
- 03Vehicle-specific mechanical or control issue
A sensible sequence
Best diagnostic order
- 01Record all available module faults
- 02Identify the affected brake, stability, steering or suspension system. Compare module data with actual operation and test the named circuit using vehicle-specific service instructions.
- 03Compare results with vehicle-specific service information
- 04Verify the repair
Step by step
What to check and repair
- 01Identify the affected brake, stability, steering or suspension system. Compare module data with actual operation and test the named circuit using vehicle-specific service instructions.
- 02Repair the verified cause and rescan all affected modules

What C059D means
Brake Pressure Sensor D Missing Calibration. The code identifies a detected condition, not a confirmed failed part. Exact behavior depends on the vehicle and control module.
Diagnostic direction
Identify the affected brake, stability, steering or suspension system. Compare module data with actual operation and test the named circuit using vehicle-specific service instructions.
Before clearing the code
Save all module faults and freeze-frame data where supported. Use service information for the exact vehicle, repair the verified cause, then confirm the warning does not return.
