Step 1: Visually inspect the right side restraints sensor 5 location (typically B-pillar, door, or seat-mounted) for physical damage, water intrusion, or impact damage. Check connector for corrosion, bent pins, or moisture contamination.

Step 2: Using a digital multimeter, measure resistance and continuity of the wiring harness between the sensor connector and RCM connector following manufacturer wiring diagrams. Verify proper ground integrity and check for short circuits to power or ground (typically should read 0.5-5 ohms continuity, infinite resistance to ground when disconnected).

Step 3: With ignition off and sensor disconnected, measure sensor internal resistance across its terminals. Compare readings to manufacturer specifications (typically 1-10K ohms depending on sensor type). Check for open circuits or short circuits within the sensor itself.

Step 4: Using the diagnostic scan tool, perform RCM self-test and monitor live data for right side sensor 5 output values while gently manipulating wiring harness and connector. Look for intermittent signal dropout or voltage fluctuations indicating loose connections.

Step 5: If all wiring and sensor resistance tests pass, substitute a known-good right side restraints sensor 5 to verify sensor failure. Clear codes and perform drive cycle to confirm repair.

Step 6: If fault persists after sensor and wiring verification, suspect RCM internal fault. Verify RCM software is up-to-date through manufacturer technical service bulletins and consider RCM replacement if all other components test normal.
