Step 1: Perform visual inspection of steering column area for signs of previous collision damage, deployed mechanisms, or physical misalignment. Check for any loose or damaged components in the collapsible section of the steering column.

Step 2: Inspect all wiring harnesses and connectors associated with the steering column sensors and actuators. Look for corrosion, bent pins, water intrusion, or chafed wires, particularly at the base of the steering column where wiring flexes.

Step 3: Using a digital multimeter, test voltage supply and ground circuits to the steering column position sensor and deployment actuator according to manufacturer specifications (typically 5V reference and clean ground). Check for opens, shorts to ground, or shorts to power.

Step 4: Access live data through diagnostic software to monitor steering column sensor values and compare to known-good specifications. Check for erratic readings or values outside normal operating range.

Step 5: Perform resistance and continuity tests on the collapsible column actuator or sensor using a multimeter. Compare readings to factory specifications to identify internal component failures.

Step 6: If all circuits and components test normal, perform functional testing of the restraint control module or body control module, and verify proper software calibration. Consider module replacement or reprogramming if all other components pass testing.
