Porsche Axial Acceleration Sensor Calibration

Supported coding features by PoCOM diagnostic tool https://www.obdtester.com/pocom

Axial Acceleration Sensor Calibration

What it does

• Calibrates the longitudinal (axial) acceleration sensor
• Provides correct acceleration and deceleration reference values
• Supports ABS, PSM, and traction control systems

When it is required

• After axial acceleration sensor replacement
• After ABS or PSM control unit replacement
• After suspension or chassis repairs
• When stability control fault codes are present

Conditions that must be met

• Vehicle stationary on level ground
• Ignition ON
• Stable battery voltage
• Diagnostic tool connected
• No active critical ABS/PSM faults

What happens during calibration

• Sensor zero point is detected and stored
• Control unit updates longitudinal dynamics calculations
• System verifies plausibility of sensor signals

If calibration is not performed

• Incorrect stability or traction control intervention
• Fault codes or warning lights may remain
• Reduced driving stability and safety

After calibration

• Verify sensor values in live data
• Clear fault codes if present
• Perform a short test drive
• Confirm proper ABS/PSM operation
