Absolute Steering Position Calibration

What it does

• Calibrates the absolute steering wheel center position
• Provides accurate steering angle data to:
• EPS (Electric Power Steering)
• ESC / ABS
• Ensures correct steering assistance and stability control behavior

When it is required

• After replacing the steering angle sensor
• After EPS module replacement
• After wheel alignment
• After steering column or rack work
• When steering or ESC fault codes are present

Conditions that must be met

• Front wheels aligned straight ahead
• Steering wheel centered
• Vehicle on level ground
• Ignition ON, engine OFF (or as instructed)
• No active EPS or ESC fault codes
• Stable battery voltage

What happens during calibration

• Sensor zero (center) position is stored
• Steering angle plausibility is verified
• Data is synchronized between EPS and ESC modules

If calibration is not performed

• Steering warning light may remain active
• Incorrect steering assistance
• ESC intervention may be incorrect

After calibration

• Turn steering wheel lock-to-lock if requested
• Perform a short test drive
• Confirm stable steering behavior
• Verify no steering-related warnings remain
